Function Documentation

status_t LPI2C_RTOS_Init ( lpi2c_rtos_handle_t *  handle,
LPI2C_Type *  base,
const lpi2c_master_config_t masterConfig,
uint32_t  srcClock_Hz 
)

This function initializes the LPI2C module and related RTOS context.

Parameters
handleThe RTOS LPI2C handle, the pointer to an allocated space for RTOS context.
baseThe pointer base address of the LPI2C instance to initialize.
masterConfigConfiguration structure to set-up LPI2C in master mode.
srcClock_HzFrequency of input clock of the LPI2C module.
Returns
status of the operation.
status_t LPI2C_RTOS_Deinit ( lpi2c_rtos_handle_t *  handle)

This function deinitializes the LPI2C module and related RTOS context.

Parameters
handleThe RTOS LPI2C handle.
status_t LPI2C_RTOS_Transfer ( lpi2c_rtos_handle_t *  handle,
lpi2c_master_transfer_t *  transfer 
)

This function performs an I2C transfer using LPI2C module according to data given in the transfer structure.

Parameters
handleThe RTOS LPI2C handle.
transferStructure specifying the transfer parameters.
Returns
status of the operation.
