Whisker supports touchscreens via the Universal Pointing Device Driver (UPDD) from TouchBase (http://www.touch-base.com). It does not support the use of touchscreens with the drivers from touchscreen manufacturers.
Therefore, the installation sequences is:
| 1. | Set any hardware switches on the touchscreen and plug it into your computer. |
| 2. | If your touchscreen is plugged into a serial port, ensure that the port has the correct settings. For example, here's how to configure ports for XON/OFF handshaking. |
| 3. | Configure, enable and calibrate the touchscreen via the UPDD configuration utility |
Tip
Note that the touchscreen must be enabled and controlled via UPDD before you configure Whisker.
Do not install drivers that come with the touchscreen - let UPDD control it for you. The touchscreen drivers will usually turn your touchscreen into a mouse as far as Windows (and therefore Whisker) is concerned.
At this stage, you should see all of the touchscreens from the UPDD control panel.
| 4. | Once UPDD communicates successfully with the touchscreen, Whisker will detect it. To check this, choose Configure hardware → Touchscreens. All touchscreens that UPDD has detected should be listed; if not, check the server event log for errors. Assign touchscreens to display devices. |
| 5. | Test display devices: Display → Show test pattern on all displays. Now touch the touchscreens! |
