Touchscreen - Eurotech Apollo Quick Start Manual

APOLLO Windows XP Embedded Quickstart

Touchscreen

The flat panel version of the Development Kit is supplied with a touchscreen. A driver
for the touchscreen is included, but is not enabled by default as it utilises a COM port.
A shortcut is provided on the desktop to make it straightforward to start the
touchscreen driver.
To use the touchscreen on your flat panel, follow these steps:
1 Ensure the APOLLO 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 TSC1, using the 8-wire connector.
5 Connect the output of the TSC1 to serial port COM3 (J22) on the APOLLO board.
6 Make sure that jumpers LK2, LK3, LK4 and LK6 are fitted on the TSC1, so that it
is operating in 10-bit mode.
7 Switch the APOLLO on and allow it to boot into Windows XP.
8 Using a mouse, double-click the Touchscreen Driver icon on the desktop.
The touchscreen and TSC1 are configured and calibrated as part of Eurotech Ltd's
production process, so are ready to use. If the touchscreen needs to be recalibrated,
launch the calibration process by selecting Run from the Start menu and typing
"arctouch –c".
If you download a new XP image to the APOLLO, the calibration routine is carried out
the first time the touchscreen driver is run.
To make the touchscreen driver start automatically every time Windows XP Embedded
starts, copy the shortcut on the desktop to the Startup folder on the Start menu.
For more details, refer to the document Touchscreen.html. This is on the DVD that
accompanies this Development Kit, in the folder Documentation\Datasheets\TSC1.

Make sure that the touchscreen data wires are kept away from the
power wires for the LCD backlight and inverter, as this can cause
interference and erratic behaviour from the touchscreen.
Pin 1 is marked on the touchscreen with an arrow. The 8-wire ribbon
cable must be orientated so the red wire is connected to pin 1.
