This function initializes the converter configuration structure with available settings. The default values are:

config->enableAsynchronousClockOutput = true;
config->enableOverWrite =               false;

Parameters:

config – Pointer to the configuration structure.

void ADC_SetChannelConfig(ADC_Type *base, uint32_t channelGroup, const adc_channel_config_t *config)

Configures the conversion channel.

This operation triggers the conversion when in software trigger mode. When in hardware trigger mode, this API configures the channel while the external trigger source helps to trigger the conversion.

Note that the “Channel Group” has a detailed description. To allow sequential conversions of the ADC to be triggered by internal peripherals, the ADC has more than one group of status and control registers, one for each conversion. The channel group parameter indicates which group of registers are used, for example channel group 0 is for Group A registers and channel group 1 is for Group B registers. The channel groups are used in a “ping-pong” approach to control the ADC operation. At any point, only one of the channel groups is actively controlling ADC conversions. The channel group 0 is used for both software and hardware trigger modes. Channel groups 1 and greater indicate potentially multiple channel group registers for use only in hardware trigger mode. See the chip configuration information in the appropriate MCU reference manual about the number of SC1n registers (channel groups) specific to this device. None of the channel groups 1 or greater are used for software trigger operation. Therefore, writing to these channel groups does not initiate a new conversion. Updating the channel group 0 while a different channel group is actively controlling a conversion is allowed and vice versa. Writing any of the channel group registers while that specific channel group is actively controlling a conversion aborts the current conversion.

Parameters:

base – ADC peripheral base address.
channelGroup – Channel group index.
config – Pointer to the “adc_channel_config_t” structure for the conversion channel.

static inline uint32_t ADC_GetChannelConversionValue(ADC_Type *base, uint32_t channelGroup)

Gets the conversion value.

Parameters:

base – ADC peripheral base address.
channelGroup – Channel group index.

Returns:

Conversion value.

static inline uint32_t ADC_GetChannelStatusFlags(ADC_Type *base, uint32_t channelGroup)

Gets the status flags of channel.

A conversion is completed when the result of the conversion is transferred into the data result registers. (provided the compare function & hardware averaging is disabled), this is indicated by the setting of COCOn. If hardware averaging is enabled, COCOn sets only, if the last of the selected number of conversions is complete. If the compare function is enabled, COCOn sets and conversion result data is transferred only if the compare condition is true. If both hardware averaging and compare functions are enabled, then COCOn sets only if the last of the selected number of conversions is complete and the compare condition is true.

Parameters:

base – ADC peripheral base address.
channelGroup – Channel group index.

Returns:

Status flags of channel.return 0 means COCO flag is 0,return 1 means COCOflag is 1.

status_t ADC_DoAutoCalibration(ADC_Type *base)

Automates the hardware calibration.

This auto calibration helps to adjust the plus/minus side gain automatically. Execute the calibration before using the converter. Note that the software trigger should be used during calibration.

Note

1. This function can only be used to get unfinished major loop count of transfer without the next TCD, or it might be inaccuracy.

The unfinished/remaining transfer bytes cannot be obtained directly from registers while the channel is running. Because to calculate the remaining bytes, the initial NBYTES configured in DMA_TCDn_NBYTES_MLNO register is needed while the eDMA IP does not support getting it while a channel is active. In another word, the NBYTES value reading is always the actual (decrementing) NBYTES value the dma_engine is working with while a channel is running. Consequently, to get the remaining transfer bytes, a software-saved initial value of NBYTES (for example copied before enabling the channel) is needed. The formula to calculate it is shown below: RemainingBytes = RemainingMajorLoopCount * NBYTES(initially configured)

Parameters:

base – eDMA peripheral base address.
channel – eDMA channel number.

Returns:

Major loop count which has not been transferred yet for the current TCD.

static inline uint32_t EDMA_GetErrorStatusFlags(DMA_Type *base)

void EDMA_HandleIRQ(edma_handle_t *handle)

eDMA IRQ handler for the current major loop transfer completion.

This function clears the channel major interrupt flag and calls the callback function if it is not NULL.

Note: For the case using TCD queue, when the major iteration count is exhausted, additional operations are performed. These include the final address adjustments and reloading of the BITER field into the CITER. Assertion of an optional interrupt request also occurs at this time, as does a possible fetch of a new TCD from memory using the scatter/gather address pointer included in the descriptor (if scatter/gather is enabled).

For instance, when the time interrupt of TCD[0] happens, the TCD[1] has already been loaded into the eDMA engine. As sga and sga_index are calculated based on the DLAST_SGA bitfield lies in the TCD_CSR register, the sga_index in this case should be 2 (DLAST_SGA of TCD[1] stores the address of TCD[2]). Thus, the “tcdUsed” updated should be (tcdUsed - 2U) which indicates the number of TCDs can be loaded in the memory pool (because TCD[0] and TCD[1] have been loaded into the eDMA engine at this point already.).

For the last two continuous ISRs in a scatter/gather process, they both load the last TCD (The last ISR does not load a new TCD) from the memory pool to the eDMA engine when major loop completes. Therefore, ensure that the header and tcdUsed updated are identical for them. tcdUsed are both 0 in this case as no TCD to be loaded.

See the “eDMA basic data flow” in the eDMA Functional description section of the Reference Manual for further details.

Parameters:

handle – eDMA handle pointer.

In scatter gather mode, this parameter shows is the current transfer block in EDMA register is done. As the load of core is different, it will be different if the new tcd loaded into EDMA registers while this callback called. If true, it always means new tcd still not loaded into registers, while false means new tcd already loaded into registers.

}

Parameters:

base – ENET peripheral base address.
handle – The ENET handler structure. This is the same handler pointer used in the ENET_Init.
data – The data buffer provided by user to store the frame which memory size should be at least “length”.
length – The size of the data buffer which is still the length of the received frame.
ringId – The ring index or ring number.
ts – The timestamp address to store received timestamp.

Returns:

Transmits an ENET frame for specified ring.

Note

The CRC is automatically appended to the data. Input the data to send without the CRC. This API uses memcpy to copy data from DMA buffer to application buffer, 4 bytes aligned data buffer in 32 bits platforms provided by user may let compiler use optimization instruction to reduce time consumption.

Parameters:

base – ENET peripheral base address.
handle – The ENET handler pointer. This is the same handler pointer used in the ENET_Init.
data – The data buffer provided by user to send.
length – The length of the data to send.
ringId – The ring index or ring number.
tsFlag – Timestamp enable flag.
context – Used by user to handle some events after transmit over.

Return values:

kStatus_Success – Send frame succeed.
kStatus_ENET_TxFrameBusy – Transmit buffer descriptor is busy under transmission. The transmit busy happens when the data send rate is over the MAC capacity. The waiting mechanism is recommended to be added after each call return with kStatus_ENET_TxFrameBusy.

status_t ENET_SetTxReclaim(enet_handle_t *handle, bool isEnable, uint8_t ringId)

Enable or disable tx descriptors reclaim mechanism.

Note

This function must be called when no pending send frame action. Set enable if you want to reclaim context or timestamp in interrupt.

Parameters:

handle – The ENET handler pointer. This is the same handler pointer used in the ENET_Init.
isEnable – Enable or disable flag.
ringId – The ring index or ring number.

Return values:

handle – The ENET handler pointer. This is the same handler pointer used in the ENET_Init.
ringId – The ring index or ring number.

status_t ENET_GetRxFrame(ENET_Type *base, enet_handle_t *handle, enet_rx_frame_struct_t *rxFrame, uint8_t ringId)

Receives one frame in specified BD ring with zero copy.

This function uses the user-defined allocation and free callbacks. Every time application gets one frame through this function, driver stores the buffer address(es) in enet_buffer_struct_t and allocate new buffer(s) for the BD(s). If there’s no memory buffer in the pool, this function drops current one frame to keep the Rx frame in BD ring is as fresh as possible.

Note

Application must provide a memory pool including at least BD number + n buffers in order for this function to work properly, because each BD must always take one buffer while driver is running, then other extra n buffer(s) can be taken by application. Here n is the ceil(max_frame_length(set by RCR) / bd_rx_size(set by MRBR)). Application must also provide an array structure in rxFrame->rxBuffArray with n index to receive one complete frame in any case.

Parameters:

base – ENET peripheral base address.
handle – The ENET handler pointer. This is the same handler pointer used in the ENET_Init.
rxFrame – The received frame information structure provided by user.
ringId – The ring index or ring number.

Return values:

kStatus_Success – Succeed to get one frame and allocate new memory for Rx buffer.
kStatus_ENET_RxFrameEmpty – There’s no Rx frame in the BD.
kStatus_ENET_RxFrameError – There’s issue in this receiving.
kStatus_ENET_RxFrameDrop – There’s no new buffer memory for BD, drop this frame.

status_t ENET_StartTxFrame(ENET_Type *base, enet_handle_t *handle, enet_tx_frame_struct_t *txFrame, uint8_t ringId)

Sends one frame in specified BD ring with zero copy.

This function supports scattered buffer transmit, user needs to provide the buffer array.

Note

Tx reclaim should be enabled to ensure the Tx buffer ownership can be given back to application after Tx is over.

Parameters:

base – ENET peripheral base address.
handle – The ENET handler pointer. This is the same handler pointer used in the ENET_Init.
txFrame – The Tx frame structure.
ringId – The ring index or ring number.

typedef struct _enet_config enet_config_t

Defines the basic configuration structure for the ENET device.

Note:

macSpecialConfig is used for a special control configuration, A logical OR of “enet_special_control_flag_t”. For a special configuration for MAC, set this parameter to 0.
txWatermark is used for a cut-through operation. It is in steps of 64 bytes: 0/1 - 64 bytes written to TX FIFO before transmission of a frame begins. 2 - 128 bytes written to TX FIFO …. 3 - 192 bytes written to TX FIFO …. The maximum of txWatermark is 0x2F - 4032 bytes written to TX FIFO …. txWatermark allows minimizing the transmit latency to set the txWatermark to 0 or 1 or for larger bus access latency 3 or larger due to contention for the system bus.
rxFifoFullThreshold is similar to the txWatermark for cut-through operation in RX. It is in 64-bit words. The minimum is ENET_FIFO_MIN_RX_FULL and the maximum is 0xFF. If the end of the frame is stored in FIFO and the frame size if smaller than the txWatermark, the frame is still transmitted. The rule is the same for rxFifoFullThreshold in the receive direction.
When “kENET_ControlFlowControlEnable” is set in the macSpecialConfig, ensure that the pauseDuration, rxFifoEmptyThreshold, and rxFifoStatEmptyThreshold are set for flow control enabled case.
When “kENET_ControlStoreAndFwdDisabled” is set in the macSpecialConfig, ensure that the rxFifoFullThreshold and txFifoWatermark are set for store and forward disable.
The rxAccelerConfig and txAccelerConfig default setting with 0 - accelerator are disabled. The “enet_tx_accelerator_t” and “enet_rx_accelerator_t” are recommended to be used to enable the transmit and receive accelerator. After the accelerators are enabled, the store and forward feature should be enabled. As a result, kENET_ControlStoreAndFwdDisabled should not be set.
The intCoalesceCfg can be used in the rx or tx enabled cases to decrese the CPU loading.

The aligned transmit and receive buffer descriptor start address must be at least 64 bit aligned. However, it’s recommended to be evenly divisible by ENET_BUFF_ALIGNMENT. buffer descriptors should be put in non-cacheable region when cache is enabled.
The aligned transmit and receive data buffer start address must be evenly divisible by ENET_BUFF_ALIGNMENT. Receive buffers should be continuous with the total size equal to “rxBdNumber * rxBuffSizeAlign”. Transmit buffers should be continuous with the total size equal to “txBdNumber * txBuffSizeAlign”. when the data buffers are in cacheable region when cache is enabled, all those size should be aligned to the maximum value of “ENET_BUFF_ALIGNMENT” and the cache line size.

struct _enet_config

#include <fsl_enet.h>

Defines the basic configuration structure for the ENET device.

Note:

macSpecialConfig is used for a special control configuration, A logical OR of “enet_special_control_flag_t”. For a special configuration for MAC, set this parameter to 0.
txWatermark is used for a cut-through operation. It is in steps of 64 bytes: 0/1 - 64 bytes written to TX FIFO before transmission of a frame begins. 2 - 128 bytes written to TX FIFO …. 3 - 192 bytes written to TX FIFO …. The maximum of txWatermark is 0x2F - 4032 bytes written to TX FIFO …. txWatermark allows minimizing the transmit latency to set the txWatermark to 0 or 1 or for larger bus access latency 3 or larger due to contention for the system bus.
rxFifoFullThreshold is similar to the txWatermark for cut-through operation in RX. It is in 64-bit words. The minimum is ENET_FIFO_MIN_RX_FULL and the maximum is 0xFF. If the end of the frame is stored in FIFO and the frame size if smaller than the txWatermark, the frame is still transmitted. The rule is the same for rxFifoFullThreshold in the receive direction.
When “kENET_ControlFlowControlEnable” is set in the macSpecialConfig, ensure that the pauseDuration, rxFifoEmptyThreshold, and rxFifoStatEmptyThreshold are set for flow control enabled case.
When “kENET_ControlStoreAndFwdDisabled” is set in the macSpecialConfig, ensure that the rxFifoFullThreshold and txFifoWatermark are set for store and forward disable.
The rxAccelerConfig and txAccelerConfig default setting with 0 - accelerator are disabled. The “enet_tx_accelerator_t” and “enet_rx_accelerator_t” are recommended to be used to enable the transmit and receive accelerator. After the accelerators are enabled, the store and forward feature should be enabled. As a result, kENET_ControlStoreAndFwdDisabled should not be set.
The intCoalesceCfg can be used in the rx or tx enabled cases to decrese the CPU loading.

FlexIO SPI Driver

void FLEXIO_SPI_MasterInit(FLEXIO_SPI_Type *base, flexio_spi_master_config_t *masterConfig, uint32_t srcClock_Hz)

Ungates the FlexIO clock, resets the FlexIO module, configures the FlexIO SPI master hardware, and configures the FlexIO SPI with FlexIO SPI master configuration. The configuration structure can be filled by the user, or be set with default values by the FLEXIO_SPI_MasterGetDefaultConfig().

Example

FLEXIO_SPI_Type spiDev = {
.flexioBase = FLEXIO,
.SDOPinIndex = 0,
.SDIPinIndex = 1,
.SCKPinIndex = 2,
.CSnPinIndex = 3,
.shifterIndex = {0,1},
.timerIndex = {0,1}
};
flexio_spi_master_config_t config = {
.enableMaster = true,
.enableInDoze = false,
.enableInDebug = true,
.enableFastAccess = false,
.baudRate_Bps = 500000,
.phase = kFLEXIO_SPI_ClockPhaseFirstEdge,
.direction = kFLEXIO_SPI_MsbFirst,
.dataMode = kFLEXIO_SPI_8BitMode
};
FLEXIO_SPI_MasterInit(&spiDev, &config, srcClock_Hz);

Note

1.FlexIO SPI master only support CPOL = 0, which means clock inactive low. 2.For FlexIO SPI master, the input valid time is 1.5 clock cycles, for slave the output valid time is 2.5 clock cycles. So if FlexIO SPI master communicates with other spi IPs, the maximum baud rate is FlexIO clock frequency divided by 2*2=4. If FlexIO SPI master communicates with FlexIO SPI slave, the maximum baud rate is FlexIO clock frequency divided by (1.5+2.5)*2=8.

Parameters:

base – Pointer to the FLEXIO_SPI_Type structure.
masterConfig – Pointer to the flexio_spi_master_config_t structure.
srcClock_Hz – FlexIO source clock in Hz.

void FLEXIO_SPI_MasterDeinit(FLEXIO_SPI_Type *base)

Parameters:

base – Pointer to the FLEXIO_SPI_Type.

void FLEXIO_SPI_MasterGetDefaultConfig(flexio_spi_master_config_t *masterConfig)

flexio_spi_master_config_t masterConfig;
FLEXIO_SPI_MasterGetDefaultConfig(&masterConfig);

Parameters:

masterConfig – Pointer to the flexio_spi_master_config_t structure.

void FLEXIO_SPI_SlaveInit(FLEXIO_SPI_Type *base, flexio_spi_slave_config_t *slaveConfig)

Ungates the FlexIO clock, resets the FlexIO module, configures the FlexIO SPI slave hardware configuration, and configures the FlexIO SPI with FlexIO SPI slave configuration. The configuration structure can be filled by the user, or be set with default values by the FLEXIO_SPI_SlaveGetDefaultConfig().

Note

1.Only one timer is needed in the FlexIO SPI slave. As a result, the second timer index is ignored. 2.FlexIO SPI slave only support CPOL = 0, which means clock inactive low. 3.For FlexIO SPI master, the input valid time is 1.5 clock cycles, for slave the output valid time is 2.5 clock cycles. So if FlexIO SPI slave communicates with other spi IPs, the maximum baud rate is FlexIO clock frequency divided by 3*2=6. If FlexIO SPI slave communicates with FlexIO SPI master, the maximum baud rate is FlexIO clock frequency divided by (1.5+2.5)*2=8. Example

FLEXIO_SPI_Type spiDev = {
.flexioBase = FLEXIO,
.SDOPinIndex = 0,
.SDIPinIndex = 1,
.SCKPinIndex = 2,
.CSnPinIndex = 3,

Initializes the UART handle.

This function initializes the FlexIO UART handle, which can be used for other FlexIO UART transactional APIs. Call this API once to get the initialized handle.

The UART driver supports the “background” receiving, which means that users can set up a RX ring buffer optionally. Data received is stored into the ring buffer even when the user doesn’t call the FLEXIO_UART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, users can get the received data from the ring buffer directly. The ring buffer is disabled if passing NULL as ringBuffer.

Parameters:

base – to FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
callback – The callback function.

When the RX ring buffer is used, data received is stored into the ring buffer even when the user doesn’t call the UART_ReceiveNonBlocking() API. If there is already data received in the ring buffer, users can get the received data from the ring buffer directly.

Note

When using the RX ring buffer, one byte is reserved for internal use. In other words, if ringBufferSize is 32, only 31 bytes are used for saving data.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
ringBuffer – Start address of ring buffer for background receiving. Pass NULL to disable the ring buffer.

This function sends data using an interrupt method. This is a non-blocking function, which returns directly without waiting for all data to be written to the TX register. When all data is written to the TX register in ISR, the FlexIO UART driver calls the callback function and passes the kStatus_FLEXIO_UART_TxIdle as status parameter.

Note

The kStatus_FLEXIO_UART_TxIdle is passed to the upper layer when all data is written to the TX register. However, it does not ensure that all data is sent out.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
xfer – FlexIO UART transfer structure. See flexio_uart_transfer_t.

Return values:

kStatus_Success – Successfully starts the data transmission.
kStatus_UART_TxBusy – Previous transmission still not finished, data not written to the TX register.

void FLEXIO_UART_TransferAbortSend(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle)

Aborts the interrupt-driven data transmit.

This function aborts the interrupt-driven data sending. Get the remainBytes to find out how many bytes are still not sent out.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.

status_t FLEXIO_UART_TransferGetSendCount(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, size_t *count)

Gets the number of bytes sent.

This function gets the number of bytes sent driven by interrupt.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
count – Number of bytes sent so far by the non-blocking transaction.

Return values:

kStatus_NoTransferInProgress – transfer has finished or no transfer in progress.
kStatus_Success – Successfully return the count.

status_t FLEXIO_UART_TransferReceiveNonBlocking(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, flexio_uart_transfer_t *xfer, size_t *receivedBytes)

Receives a buffer of data using the interrupt method.

This function receives data using the interrupt method. This is a non-blocking function, which returns without waiting for all data to be received. If the RX ring buffer is used and not empty, the data in ring buffer is copied and the parameter receivedBytes shows how many bytes are copied from the ring buffer. After copying, if the data in ring buffer is not enough to read, the receive request is saved by the UART driver. When new data arrives, the receive request is serviced first. When all data is received, the UART driver notifies the upper layer through a callback function and passes the status parameter kStatus_UART_RxIdle. For example, if the upper layer needs 10 bytes but there are only 5 bytes in the ring buffer, the 5 bytes are copied to xfer->data. This function returns with the parameter receivedBytes set to 5. For the last 5 bytes, newly arrived data is saved from the xfer->data[5]. When 5 bytes are received, the UART driver notifies upper layer. If the RX ring buffer is not enabled, this function enables the RX and RX interrupt to receive data to xfer->data. When all data is received, the upper layer is notified.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
xfer – UART transfer structure. See flexio_uart_transfer_t.
receivedBytes – Bytes received from the ring buffer directly.

Return values:

kStatus_Success – Successfully queue the transfer into the transmit queue.
kStatus_FLEXIO_UART_RxBusy – Previous receive request is not finished.

void FLEXIO_UART_TransferAbortReceive(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle)

Aborts the receive data which was using IRQ.

This function aborts the receive data which was using IRQ.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.

status_t FLEXIO_UART_TransferGetReceiveCount(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, size_t *count)

Note

The function also enables the NVIC IRQ for the input LPI2C. Need to notice that on some SoCs the LPI2C IRQ is connected to INTMUX, in this case user needs to enable the associated INTMUX IRQ in application.

Parameters:

handle – [out] Pointer to the LPI2C slave driver handle.
callback – User provided pointer to the asynchronous callback function.
userData – User provided pointer to the application callback data.

status_t LPI2C_SlaveTransferNonBlocking(LPI2C_Type *base, lpi2c_slave_handle_t *handle, uint32_t eventMask)

Starts accepting slave transfers.

Call this API after calling I2C_SlaveInit() and LPI2C_SlaveTransferCreateHandle() to start processing transactions driven by an I2C master. The slave monitors the I2C bus and pass events to the callback that was passed into the call to LPI2C_SlaveTransferCreateHandle(). The callback is always invoked from the interrupt context.

The set of events received by the callback is customizable. To do so, set the eventMask parameter to the OR’d combination of lpi2c_slave_transfer_event_t enumerators for the events you wish to receive. The kLPI2C_SlaveTransmitEvent and kLPI2C_SlaveReceiveEvent events are always enabled and do not need to be included in the mask. Alternatively, you can pass 0 to get a default set of only the transmit and receive events that are always enabled. In addition, the kLPI2C_SlaveAllEvents constant is provided as a convenient way to enable all events.

Parameters:

base – The LPI2C peripheral base address.
handle – Pointer to lpi2c_slave_handle_t structure which stores the transfer state.
eventMask – Bit mask formed by OR’ing together lpi2c_slave_transfer_event_t enumerators to specify which events to send to the callback. Other accepted values are 0 to get a default set of only the transmit and receive events, and kLPI2C_SlaveAllEvents to enable all events.

Return values:

kStatus_Success – Slave transfers were successfully started.
kStatus_LPI2C_Busy – Slave transfers have already been started on this handle.

status_t LPI2C_SlaveTransferGetCount(LPI2C_Type *base, lpi2c_slave_handle_t *handle, size_t *count)

Gets the slave transfer status during a non-blocking transfer.

Parameters:

base – The LPI2C peripheral base address.
handle – Pointer to i2c_slave_handle_t structure.
count – [out] Pointer to a value to hold the number of bytes transferred. May be NULL if the count is not required.

Return values:

flushRxFifo – Flushes (true) the Rx FIFO, else do not flush (false) the Rx FIFO.

static inline void LPSPI_SetFifoWatermarks(LPSPI_Type *base, uint32_t txWater, uint32_t rxWater)

Sets the transmit and receive FIFO watermark values.

This function allows the user to set the receive and transmit FIFO watermarks. The function does not compare the watermark settings to the FIFO size. The FIFO watermark should not be equal to or greater than the FIFO size. It is up to the higher level driver to make this check.

Parameters:

base – LPSPI peripheral address.
txWater – The TX FIFO watermark value. Writing a value equal or greater than the FIFO size is truncated.
rxWater – The RX FIFO watermark value. Writing a value equal or greater than the FIFO size is truncated.

static inline void LPSPI_SetAllPcsPolarity(LPSPI_Type *base, uint32_t mask)

Configures all LPSPI peripheral chip select polarities simultaneously.

Note that the CFGR1 should only be written when the LPSPI is disabled (LPSPIx_CR_MEN = 0).

This is an example: PCS0 and PCS1 set to active low and other PCSs set to active high. Note that the number of PCS is device-specific.

LPSPI_SetAllPcsPolarity(base, kLPSPI_Pcs0ActiveLow | kLPSPI_Pcs1ActiveLow);

Parameters:

base – LPSPI peripheral address.
mask – The PCS polarity mask; Use the enum _lpspi_pcs_polarity.

static inline void LPSPI_SetFrameSize(LPSPI_Type *base, uint32_t frameSize)

Configures the frame size.

The minimum frame size is 8-bits and the maximum frame size is 4096-bits. If the frame size is less than or equal to 32-bits, the word size and frame size are identical. If the frame size is greater than 32-bits, the word size is 32-bits for each word except the last (the last word contains the remainder bits if the frame size is not divisible by 32). The minimum word size is 2-bits. A frame size of 33-bits (or similar) is not supported.

Note 1: The transmit command register should be initialized before enabling the LPSPI in slave mode, although the command register does not update until after the LPSPI is enabled. After it is enabled, the transmit command register should only be changed if the LPSPI is idle.

Note 2: The transmit and command FIFO is a combined FIFO that includes both transmit data and command words. That means the TCR register should be written to when the Tx FIFO is not full.

Parameters:

base – LPSPI peripheral address.
frameSize – The frame size in number of bits.

uint32_t LPSPI_MasterSetBaudRate(LPSPI_Type *base, uint32_t baudRate_Bps, uint32_t srcClock_Hz, uint32_t *tcrPrescaleValue)

Sets the LPSPI baud rate in bits per second.

This function takes in the desired bitsPerSec (baud rate) and calculates the nearest possible baud rate without exceeding the desired baud rate and returns the calculated baud rate in bits-per-second. It requires the caller to provide the frequency of the module source clock (in Hertz). Note that the baud rate does not go into effect until the Transmit Control Register (TCR) is programmed with the prescale value. Hence, this function returns the prescale tcrPrescaleValue parameter for later programming in the TCR. The higher level peripheral driver should alert the user of an out of range baud rate input.

Note that the LPSPI module must first be disabled before configuring this. Note that the LPSPI module must be configured for master mode before configuring this.

Parameters:

base – LPSPI peripheral address.
baudRate_Bps – The desired baud rate in bits per second.
srcClock_Hz – Module source input clock in Hertz.
tcrPrescaleValue – The TCR prescale value needed to program the TCR.

Returns:

The actual calculated baud rate. This function may also return a “0” if the LPSPI is not configured for master mode or if the LPSPI module is not disabled.

void LPSPI_MasterSetDelayScaler(LPSPI_Type *base, uint32_t scaler, lpspi_delay_type_t whichDelay)

Manually configures a specific LPSPI delay parameter (module must be disabled to change the delay values).

This function configures the following: SCK to PCS delay, or PCS to SCK delay, or The configurations must occur between the transfer delay.

The delay names are available in type lpspi_delay_type_t.

The user passes the desired delay along with the delay value. This allows the user to directly set the delay values if they have pre-calculated them or if they simply wish to manually increment the value.

Note that the LPSPI module must first be disabled before configuring this. Note that the LPSPI module must be configured for master mode before configuring this.

Parameters:

base – LPSPI peripheral address.
scaler – The 8-bit delay value 0x00 to 0xFF (255).
whichDelay – The desired delay to configure, must be of type lpspi_delay_type_t.

uint32_t LPSPI_MasterSetDelayTimes(LPSPI_Type *base, uint32_t delayTimeInNanoSec, lpspi_delay_type_t whichDelay, uint32_t srcClock_Hz)

Calculates the delay based on the desired delay input in nanoseconds (module must be disabled to change the delay values).

This function calculates the values for the following: SCK to PCS delay, or PCS to SCK delay, or The configurations must occur between the transfer delay.

The delay names are available in type lpspi_delay_type_t.

The user passes the desired delay and the desired delay value in nano-seconds. The function calculates the value needed for the desired delay parameter and returns the actual calculated delay because an exact delay match may not be possible. In this case, the closest match is calculated without going below the desired delay value input. It is possible to input a very large delay value that exceeds the capability of the part, in which case the maximum supported delay is returned. It is up to the higher level peripheral driver to alert the user of an out of range delay input.

Note that the LPSPI module must be configured for master mode before configuring this. And note that the delayTime = LPSPI_clockSource / (PRESCALE * Delay_scaler).

Parameters:

base – LPSPI peripheral address.
delayTimeInNanoSec – The desired delay value in nano-seconds.
whichDelay – The desired delay to configuration, which must be of type lpspi_delay_type_t.
srcClock_Hz – Module source input clock in Hertz.

Returns:

actual Calculated delay value in nano-seconds.

static inline void LPSPI_WriteData(LPSPI_Type *base, uint32_t data)

Writes data into the transmit data buffer.

If the frame size exceeds 32-bits, the user has to manage sending the data one 32-bit word at a time. Any writes to the TDR result in an immediate push to the transmit FIFO. This function can be used for either master or slave modes.

Parameters:

base – LPSPI peripheral address.
data – The data word to be sent.

void LPUART_TransferCreateHandle(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_callback_t callback, void *userData)

Initializes the LPUART handle.

This function initializes the LPUART handle, which can be used for other LPUART transactional APIs. Usually, for a specified LPUART instance, call this API once to get the initialized handle.

The LPUART driver supports the “background” receiving, which means that user can set up an RX ring buffer optionally. Data received is stored into the ring buffer even when the user doesn’t call the LPUART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, the user can get the received data from the ring buffer directly. The ring buffer is disabled if passing NULL as ringBuffer.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.
callback – Callback function.
userData – User data.

status_t LPUART_TransferSendNonBlocking(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_t *xfer)

Transmits a buffer of data using the interrupt method.

This function send data using an interrupt method. This is a non-blocking function, which returns directly without waiting for all data written to the transmitter register. When all data is written to the TX register in the ISR, the LPUART driver calls the callback function and passes the kStatus_LPUART_TxIdle as status parameter.

Note

The kStatus_LPUART_TxIdle is passed to the upper layer when all data are written to the TX register. However, there is no check to ensure that all the data sent out. Before disabling the TX, check the kLPUART_TransmissionCompleteFlag to ensure that the transmit is finished.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.
xfer – LPUART transfer structure, see lpuart_transfer_t.

Return values:

kStatus_Success – Successfully start the data transmission.
kStatus_LPUART_TxBusy – Previous transmission still not finished, data not all written to the TX register.
kStatus_InvalidArgument – Invalid argument.

void LPUART_TransferStartRingBuffer(LPUART_Type *base, lpuart_handle_t *handle, uint8_t *ringBuffer, size_t ringBufferSize)

Sets up the RX ring buffer.

This function sets up the RX ring buffer to a specific UART handle.

When the RX ring buffer is used, data received is stored into the ring buffer even when the user doesn’t call the UART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, the user can get the received data from the ring buffer directly.

Note

When using RX ring buffer, one byte is reserved for internal use. In other words, if ringBufferSize is 32, then only 31 bytes are used for saving data.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.
ringBuffer – Start address of ring buffer for background receiving. Pass NULL to disable the ring buffer.
ringBufferSize – size of the ring buffer.

void LPUART_TransferStopRingBuffer(LPUART_Type *base, lpuart_handle_t *handle)

Aborts the background transfer and uninstalls the ring buffer.

This function aborts the background transfer and uninstalls the ring buffer.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.

size_t LPUART_TransferGetRxRingBufferLength(LPUART_Type *base, lpuart_handle_t *handle)

Get the length of received data in RX ring buffer.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.

Returns:

Length of received data in RX ring buffer.

void LPUART_TransferAbortSend(LPUART_Type *base, lpuart_handle_t *handle)

Aborts the interrupt-driven data transmit.

This function aborts the interrupt driven data sending. The user can get the remainBtyes to find out how many bytes are not sent out.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.

status_t LPUART_TransferGetSendCount(LPUART_Type *base, lpuart_handle_t *handle, uint32_t *count)

Gets the number of bytes that have been sent out to bus.

This function gets the number of bytes that have been sent out to bus by an interrupt method.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.
count – Send bytes count.

Return values:

kStatus_NoTransferInProgress – No send in progress.
kStatus_InvalidArgument – Parameter is invalid.
kStatus_Success – Get successfully through the parameter count;

status_t LPUART_TransferReceiveNonBlocking(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_t *xfer, size_t *receivedBytes)

Receives a buffer of data using the interrupt method.

This function receives data using an interrupt method. This is a non-blocking function which returns without waiting to ensure that all data are received. If the RX ring buffer is used and not empty, the data in the ring buffer is copied and the parameter receivedBytes shows how many bytes are copied from the ring buffer. After copying, if the data in the ring buffer is not enough for read, the receive request is saved by the LPUART driver. When the new data arrives, the receive request is serviced first. When all data is received, the LPUART driver notifies the upper layer through a callback function and passes a status parameter kStatus_UART_RxIdle. For example, the upper layer needs 10 bytes but there are only 5 bytes in ring buffer. The 5 bytes are copied to xfer->data, which returns with the parameter receivedBytes set to 5. For the remaining 5 bytes, the newly arrived data is saved from xfer->data[5]. When 5 bytes are received, the LPUART driver notifies the upper layer. If the RX ring buffer is not enabled, this function enables the RX and RX interrupt to receive data to xfer->data. When all data is received, the upper layer is notified.

Parameters:

base – LPUART peripheral base address.
handle – LPUART handle pointer.
xfer – LPUART transfer structure, see uart_transfer_t.
receivedBytes – Bytes received from the ring buffer directly.

Return values:

kStatus_Success – Successfully queue the transfer into the transmit queue.
kStatus_LPUART_RxBusy – Previous receive request is not finished.
kStatus_InvalidArgument – Invalid argument.

void LPUART_TransferAbortReceive(LPUART_Type *base, lpuart_handle_t *handle)

PWM: Pulse Width Modulator

status_t PWM_Init(PWM_Type *base, pwm_submodule_t subModule, const pwm_config_t *config)

Ungates the PWM submodule clock and configures the peripheral for basic operation.

This API should be called at the beginning of the application using the PWM driver. When user select PWMX, user must choose edge aligned output, becasue there are some limitation on center aligned PWMX output. When output PWMX in center aligned mode, VAL1 register controls both PWM period and PWMX duty cycle, PWMA and PWMB output will be corrupted. But edge aligned PWMX output do not have such limit. In master reload counter initialization mode, PWM period is depended by period of set LDOK in submodule 0 because this operation will reload register. Submodule 0 counter initialization cannot be master sync or master reload.

Parameters:

base – PWM peripheral base address
subModule – PWM submodule to configure
config – Pointer to user’s PWM config structure.

Returns:

kStatus_Success means success; else failed.

void PWM_Deinit(PWM_Type *base, pwm_submodule_t subModule)

Gate the PWM submodule clock.

Parameters:

base – PWM peripheral base address
subModule – PWM submodule to deinitialize

void PWM_GetDefaultConfig(pwm_config_t *config)

Fill in the PWM config struct with the default settings.

The default values are:

config->reloadSelect = kPWM_LocalReload;
config->clockSource = kPWM_BusClock;
config->prescale = kPWM_Prescale_Divide_1;
config->initializationControl = kPWM_Initialize_LocalSync;
config->forceTrigger = kPWM_Force_Local;
config->reloadFrequency = kPWM_LoadEveryOportunity;
config->reloadLogic = kPWM_ReloadImmediate;
config->pairOperation = kPWM_Independent;

Parameters:

config – Pointer to user’s PWM config structure.

status_t PWM_SetupPwm(PWM_Type *base, pwm_submodule_t subModule, const pwm_signal_param_t *chnlParams, uint8_t numOfChnls, pwm_mode_t mode, uint32_t pwmFreq_Hz, uint32_t srcClock_Hz)

Sets up the PWM signals for a PWM submodule.

The function initializes the submodule according to the parameters passed in by the user. The function also sets up the value compare registers to match the PWM signal requirements. If the dead time insertion logic is enabled, the pulse period is reduced by the dead time period specified by the user. When user select PWMX, user must choose edge aligned output, becasue there are some limitation on center aligned PWMX output. Due to edge aligned PWMX is negative true signal, need to configure PWMX active low true level to get correct duty cycle. The half cycle point will not be exactly in the middle of the PWM cycle when PWMX enabled.

Parameters:

base – PWM peripheral base address
subModule – PWM submodule to configure
chnlParams – Array of PWM channel parameters to configure the channel(s).
numOfChnls – Number of channels to configure, this should be the size of the array passed in. Array size should not be more than 3 as each submodule has 3 pins to output PWM.
mode – PWM operation mode, options available in enumeration pwm_mode_t
pwmFreq_Hz – PWM signal frequency in Hz
srcClock_Hz – PWM source clock of correspond submodule in Hz. If source clock of submodule1,2,3 is from submodule0 AUX_CLK, its source clock is submodule0 source clock divided with submodule0 prescaler value instead of submodule0 source clock.

Returns:

Returns kStatus_Fail if there was error setting up the signal; kStatus_Success otherwise

status_t PWM_SetupPwmPhaseShift(PWM_Type *base, pwm_submodule_t subModule, pwm_channels_t pwmChannel, uint32_t pwmFreq_Hz, uint32_t srcClock_Hz, uint8_t shiftvalue, bool doSync)
