Touch Controllers Reference Guide76
Note the serial communication settings restored by this command.
Application programs operating at other communication settings that
issue this command must change to the default settings to receive the
command response and re-establish communication with the
controller.
Note:
After you issue a Restore Defaults command, calibrate your
touchscreen using the Calibrate Extended command.
The Restore Defaults command requires approximately 75 to 100
milliseconds, plus the execution time of the Reset command (225 to
800 milliseconds). Therefore, the application program should wait and
be sure it receives the command response before issuing another
command to the controller.
