Function Documentation

status_t I2C_RTOS_Init ( i2c_rtos_handle_t *  handle,
I2C_Type *  base,
const i2c_master_config_t masterConfig,
uint32_t  srcClock_Hz 
)

This function initializes the I2C module and the related RTOS context.

Parameters
handleThe RTOS I2C handle, the pointer to an allocated space for RTOS context.
baseThe pointer base address of the I2C instance to initialize.
masterConfigThe configuration structure to set-up I2C in master mode.
srcClock_HzThe frequency of an input clock of the I2C module.
Returns
status of the operation.
status_t I2C_RTOS_Deinit ( i2c_rtos_handle_t *  handle)

This function deinitializes the I2C module and the related RTOS context.

Parameters
handleThe RTOS I2C handle.
status_t I2C_RTOS_Transfer ( i2c_rtos_handle_t *  handle,
i2c_master_transfer_t transfer 
)

This function performs the I2C transfer according to the data given in the transfer structure.

Parameters
handleThe RTOS I2C handle.
transferA structure specifying the transfer parameters.
Returns
status of the operation.
