uint8_t read_i2c_device	(	uint8_t	address,
		uint8_t	bytes,
		uint8_t *	data
	)

Read 1 or more bytes from an I2C device to memory.

Parameters:

	address	Address if I2C device. The bottom bit is set to enfoce an I2C read.
	bytes	Number of bytes to be returned.
	*data	Pointer to location to store values returned.

Returns:

returns error code generated from I2C transaction. Currently always returns 0.

uint8_t write_i2c_device	(	uint8_t	address,
		uint8_t	bytes,
		uint8_t *	data
	)

Write 1 or more bytes to an I2C device from memory.

Parameters:

	address	Address if I2C device. The bottom bit is cleared to enforce an I2C write.
	bytes	Number of bytes to be sent.
	*data	Pointer to location in memory of first byte of set of data.

Returns:

returns error code generated from I2C transaction. Currently always returns 0.
