Configuration Utility

A calibration program “touchcal” is provided to calibrate the touch screen and to manage tickets, serial i/o, and menu customization.

Select “1” to perform the 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 read_touch_cal in the library “touch.cpp” module to read the calibration information. The function read_touch 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.

Select “1” to enable or disable menu items.

With the “Application” prompt selected press “SPACE” to cycle through the standard applications: “Truck Storage”, “DFC”, “Checkweigher”, “788 Compatibility”, “None”, and “All”. Select the desired standard application or “All” to appear on the application menu.

With the “Custom Acitivity” prompt selected press “SPACE” to cycle through any custom activities to show on the application menu, or select “All” or “None”.

At the “File manager” prompt select “Yes” to show the file manager on the application menu.

At the “Slide show” prompt select “Yes” to show the slide show option on the application menu.

At the “Reboot” prompt select “Yes” to show the “Return to Startup” option on the application menu.

The “Auto run” prompt may be used to specify a menu item to automatically start. When specified the “Auto run secs” prompt will appear to set the number of seconds before the item starts. This feature automatically reads the appmenu.cfg file and writes changes to the appmenu.cfg file.

Select “2” to configure custom menu items.

At the “Custom” prompt press “SPACE” to cycle through existing custom menu items to edit, or select “Add” to create a new custom menu item.

Use the “Name” prompt to specify the name to appear on the menu.

Use the “1:” though “8:” prompts to specify the actions to be performed. Press “ENTER” when finished. This will write a script file such as: cust01.sh

#!/bin/sh

# Special

cd /mnt/nand/apps/spec

./spec_app

cd /mnt/nand/bin

The “Configure Custom Activity” screen will appear again. Additional custom activities may be created or edited. Press “ESC” when finished.

The “Configure Menu” screen will then appear to allow the item to be enabled.

Press “ENTER” when finished with the configuration. The “appmenu.cfg” file will then be updated. Press “ESC” twice to return to the “Application Menu”. The new custom activity will now show.
