eGalax touchscreen calibration

[stevePIman]

Hi,

I've PMd brantje, but just in case anyone else can help, here's what was said:

How does uimapper work? Does it sit on the screen event (from the kernel?) and create another event for use by XBMC with scaled coordinates? I've done more tests and cannot see any proof that a new event is created if that is the case:

Quote:pi@raspbmc:/scripts/uinput-mapper$ sudo start uimapper
uimapper start/running, process 15186
pi@raspbmc:/scripts/uinput-mapper$ ps aux|grep input-
root 15403 0.7 1.3 8332 5084 ? S< 13:30 0:00 python ./input-read.py /dev/input/event2 -v
root 15404 0.5 1.3 8416 5076 ? S< 13:30 0:00 python ./input-create.py configs/touchscreen.py

pi@raspbmc:/scripts/uinput-mapper$ evtest
