i2c_sn3218_reset()

bool i2c_sn3218_reset

(

i2c_sn3218_update()

bool i2c_sn3218_update	(	const int	busHandle,
		const i2c_sn3218_state *	state
	)

Configure SN3218 chip to match state object.

Sends configuration commands followed by an update command to a connected SN3218 device.

As we cannot read state from the chip, all LEDs must be configured on each request.

Parameters

busHandle	Handle for I2C bus opened with i2c_openConnection()
state	Pointer to i2c_sn3218_state object

Returns

true on successful write of all commands, false otherwise
