Touch Controllers Reference Guide26
AutoBaud Disable
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>AD<CR>
Description: Turns off the automatic baud rate detection feature.
When you disable AutoBaud, the controller maintains the
communication rate currently set in non-volatile RAM (NOVRAM).
The controller continues to use this communication rate until you
change it with either the Parameter Set command or the AutoBaud
Enable command.
AutoBaud Enable is the factory default for some touchscreen
controllers. However, because this automatic feature is limited to the
communication rate, MicroTouch recommends that you issue an
AutoBaud Disable command to turn off the AutoBaud feature. After
you disable AutoBaud, send a Parameter Set command to change the
communication parameters (parity, number of data bits, number of
stop bits, and baud rate).
Response: <SOH>0<CR> Positive response.
