Function Documentation

bool HTACreadAllAxes	(	tSensors	link,
		int &	x,
		int &	y,
		int &	z
	)

Read the value of all the axes registers return by reference

Parameters:

link	the HTAC port number
x	x axis
y	y axis
z	z axis

Returns:

true if no error occured, false if it did

Examples:

hitechnic-accelerometer-SMUX-test1.c, and hitechnic-accelerometer-test1.c.
