eGalax touchscreen calibration

[TobyM]

Cheers everybody,

a sleepless night brought me some new results on xbian in combination with my Acer T230H Touch Screen:

1. The actual XBian Alpha 5 is working best, but the click_confines value is too small so you have to tap two times precisely on the same spot to make it work.

2. The actual xbmc-nightly gives me much trouble, the cursor is jumping wildly I think related to eGalaxpatch:

Code:

+ {
+ m_mouseX = g_graphicsContext.GetWidth() + 1;
+ m_mouseY = g_graphicsContext.GetHeight() + 1;
+ } */

which brings me to

3. The actual nightly does not, to any extend, use the /usr/share/eGalaxCalibration/touchscreen_axes_calib file when working with that touchscreen. The reason might be

4. The Acer T230H Screen is named: "Acer T230H" and, as far as I understand the code of the eGalaxPatch:

Code:

if(strstr(m_deviceName, "eGalax") || strstr(m_deviceName, "Touch"))
+ {
+   ...
+ }

is looking straight for the eGalax or a device named "touch".

So could someone add the Acer T230H to the nightly and to the eGalaxpatch, to be propper recognized? And perhaps, rename the patch - Touchscreen-patch?

I'll attach some info (all gained from a running xbian Alpha 5), if you need something else please let me know.

The evtest shows touchscreen working properly; the coordinates make sense, BTN_TOUCH code 330 is working too.


Thanks everyone

PPS: Perhaps it might be better in terms of readability if we split off the Acer T230H discussion into a new thread. I didn't want to capture this thread, sorry if I did so. But if no one is offended by it - I'd like to stay
