Configuration Utility

A calibration program, called touchcal, is provided to calibrate the touch screen, manage tickets, setup serial I/O, and provide menu customization.

Main Menu

Select 1 to perform the touch screen calibration. This will place a target at each corner of the display and wait for a touch. Best accuracy will be obtained using a stylus. When complete a calibration file touchcal.dat is written. Apps may call the fuction ReadTouchCal in the lib825 touch.cpp module to read the calibration information. The function ReadTouch in touch.cpp will then adjust the values obtained by the driver /dev/cardtouch to appropriate pixel coordinates X = 0 – 639 Y = 0 – 479 based on the calibration.

Select 2 to display a tracking screen to verify the correct operation of the touch screen. Press “ESC” to exit from this screen.

Select 3 to select color mode.

Select 4 to configure the weight server.

Select 5 for ticket settings.

Select 6 to configure the application menu.
