Chapter 2 Firmware Commands 57
Mode Down/Up
Note:
MicroTouch provides this command for compatibility with older touchscreen
controllers. To ensure compatibility with all existing and future MicroTouch controllers,
do not use this command when developing your touch drivers and applications.
Syntax: <SOH>MDU<CR>
Description: Send one X, Y coordinate for each touchdown and each liftoff on the
touchscreen.
In Mode Down/Up, the controller sends the first X, Y coordinate
when the screen is touched, sends no data while the touch is held, and
sends a second X, Y coordinate at touch liftoff. The format of the
coordinate data depends on the last format command received by the
controller.
Response: <SOH>0<CR> Positive response.
