SBC-GX1 Windows XP Embedded Quickstart Touchscreen
Touchscreen
The LCD version of the development kit is supplied with a touchscreen. A driver for the
touchscreen is included, but is disabled by default as it takes over a COM port. The
TSC1 touchscreen drivers include the following programs:
Main driver: Touchscreen.exe •
•
•
Calibration program: Touchcal.exe.
Diagnostic program: Touchraw.exe.
To use the touchscreen on your flat panel, follow these steps:
1 Ensure the SBC-GX1 is powered off and the touchscreen is fixed securely to the
flat panel.
2 Ensure that all electrical connections for the touchscreen and touchscreen
controller are made.
3 Connect a +5V supply to the touchscreen controller, using the supplied cable.
4 Connect the touchscreen to the touchscreen controller, using the 4-wire
connector.
Make sure that pin 1 of the TSC1 goes to pin 1 of the touchscreen.
5 Connect the output of the touchscreen controller to serial port COM3 (PL27) on
the SBC-GX1 board.
6 Start the SBC-GX1.
7 Create a shortcut to touchscreen.exe and place the shortcut in the Startup folder
of Windows XP Embedded.
8 Restart the system.
The touchscreen and TSC1 are configured and calibrated as part of the production
process, so are ready to use.
The touchscreen driver includes an automatic detection routine. This determines which
COM port and baud rate to use. This is not normally required, but can be initiated by
deleting the following two registry values in the key:
HKEY_LOCAL_MACHINE\Software\Arcom Control Systems\Touchscreen
"Calibrated"=dword:00000001
"TSC1Detected"=dword:00000001
