Downloadable macro reference

	SampleSensor
Reads the touch controller and returns true if there is currently a touch in progress. The touch coordinates can be read using the ReadCoord macro. Return 0 = No Touch, 1 = Touch in progress
- BYTE	Return

	ReadCoord
Reads a coordinate returned from the Sample Sensor macro. Coordinate is scaled to the X/Y Pixel bounds specified.
- BYTE	Coordinate
0 = X, 1 = Y, 2 = Pressure
- UINT	Return

	Initialise
Activates the SPI peripheral and claims control over the I/O pins.
