Issue: Calibration of Touchscreen under Raspbian

A great Link collection for touch calibration tools: http://tias.ulyssis.org/calibration/ and a great overview of the whole USB-HID and USB-non-hid touch issue: http://tias.ulyssis.org/calibration/device_support.html

Raspberry Pi Touchscreen

All informations about my raspberry pi touchscreen.

This is my 7" touchscreen, which i bought from an ebay seller called chinatobby2011 . It was an auction and i won it with a 45 EUR bid (free shipping).


An overview of the whole stuff linked together you can find in this video:



Its a 7" resistive touchscreen and called AT070TN92 V.5. This Touchpanel is linked to a controller board called VS-TY2662-V1 or PCB800099. I have made a screenshot from the ebay auction: goo.gl/hd9Nt  The auction title is: "HDMI+VGA+2AV Driver board+7inch 800*480 AT070TN92 V.5 Lcd with touch panel".
The direct link to the auction is: www.ebay.com/itm/170937641798

There are several issues:

The drivers, which are shipped with the board do not support ARM chipsets. (And the raspberry pi is based onARM architecture).
But i have found out, that rasbian delivers a driver:

egalax driver for raspberry pi
You just have to recompile the kernel.
(Howto will be created soon)
 

New Blog!

After my old blog crashed with a not known database issue, i will start over here on googles blogspot. So no database problems and hosting issues. Just naked hardware & software hacking stuff in your face ! ;-)
In the last few weeks the raspberry pi catched my attention and i am going to post several videos and howto stuff here. Furthermore, i have a lot of other hardware stuff to publish and archive here for interested geeks.

You can find my older videos on youtube:
