Hi Netzman,

Wow, i had a look at your wiki and the code, and it looks like a great piece of work.
You included rotation too. It is well documented on the wiki too.
I hope you can add some video demo when possible.
Thanks for sharing !

Hi Netzman

I have tried to download and open the Zip Folder of the touch screen but, when i try to extract the files it says that the Zip file is corrupt.
Can you please let me know how I can open these files?

Regards

Craig

Hi,

very strange, that's the second time there are problems with my zip archives... this time I can track the error, i suspect the Windows 7x64 Explorer Zip function to be faulty... I have repacked the archive using 7zip and uploaded it, please try again.

Best regards

Hi,

just a small update, V. 1.1:
- Increased max. delta to 5000 pixels/sec to match handwriting speed
- Fixed a little bug in calculating the rotated coordinates

also added a demo video.
