initAccelerometer()

void initAccelerometer	(	Accelerometer *	accel,
		int	channel,
		int	hz,
		int	muxChannel
	)

Initializes the accelerometer with the given channel, frequency, and multiplexer channel.

Parameters

accel	Pointer to the Accelerometer structure to initialize.
channel	The analog channel the accelerometer is connected to.
hz	The frequency in Hertz at which the accelerometer operates.
muxChannel	The multiplexer channel for the accelerometer.
