bool8_t I2CWrite	(	TpDeviceHandle_t	hDevice,
		uint16_t	wAddress,
		void *	pBuffer,
		uint32_t	dwSize,
		bool8_t	bStop
	)

Write data to the I2C bus.

Parameters

hDevice	A device handle.
wAddress	An I2C device address.
pBuffer	Pointer to write buffer.
dwSize	Length of write buffer in bytes.
bStop	If BOOL8_TRUE an I2C stop is generated after the transaction, if BOOL8_FALSE no I2C stop is generated after the transaction.

Returns

BOOL8_TRUE if successful, BOOL8_FALSE otherwise.
