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

handle	The RTOS I2C handle, the pointer to an allocated space for RTOS context.
base	The pointer base address of the I2C instance to initialize.
masterConfig	The configuration structure to set-up I2C in master mode.
srcClock_Hz	The frequency of an input clock of the I2C module.

Returns

status of the operation.
