Function Documentation

◆ fxls8471q_isr()

void fxls8471q_isr ( void * pUserData )

This is the Sensor Data Ready ISR implementation.

This function sets the flag which indicates if a new sample(s) is available for reading.

Parameters

[in] pUserData This is a void pointer to the instance of the user specific data structure for the ISR.

Returns: void There is no return value.

Constraints:: None
Yes

Set flag to indicate Sensor has signalled data ready.

Here is the caller graph for this function:

◆ main()

int main ( void )

This is the The main function implementation.

This function invokes board initializes routines, then then brings up the sensor and finally enters an endless loop to continuously read available samples.

Parameters

[in] void This is no input parameter.

Returns: void There is no return value.

Constraints:: None
No

Initialize the MCU hardware.

Initialize INT1_FXLS8471Q pin used by board

Initialize RGB LED pin used by board

Initialize the SPI driver.

Set the SPI Power mode.

Set the SPI Slave speed.

Initialize the FXLS8471Q sensor driver.

Set the task to be executed while waiting for SPI transactions to complete.

Configure the FXLS8471Q sensor driver.

Clear the data ready flag, it will be set again by the ISR.

Read the raw sensor data from the FXLS8471Q.

Convert the raw sensor data to signed 16-bit container for display to the debug port.
