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

handle	The RTOS LPI2C handle, the pointer to an allocated space for RTOS context.
base	The pointer base address of the LPI2C instance to initialize.
masterConfig	Configuration structure to set-up LPI2C in master mode.
srcClock_Hz	Frequency of input clock of the LPI2C module.

Returns

status of the operation.

status_t LPI2C_RTOS_Deinit

(

lpi2c_rtos_handle_t *

handle

)
