5.10 Touch screen macros
You can use the touch screen macros to determine the position of the pointing device.
RC200TouchScreenReadRaw() determines the position in raw coordinates.
RC200TouchScreenReadScaled() determines the position scaled to 640 x 480 resolution.
You need to run these macros in parallel with
RC200TouchScreenRun().
