Noobs Touchscreen Support #187

Closed derFrickler closed 10 years ago

derFrickler commented 10 years ago

I have a small 7" TFT with an USB Touchscreen on my Raspberry. http://www.pollin.de/shop/dt/NTMwOTc4OTk-/Bauelemente_Bauteile/Aktive_Bauelemente/Displays/7_17_78_cm_Display_Set_mit_Touchscreen_LS_7T_HDMI_DVI_VGA_CVBS.html

The touchscreen works out of the Box in Raspbian and even in Noobs. The only problem is that in Noobs i have no way of calibrating the touch or at least specifying calibration values. Is there any way to do this?

You can find a tutorial on how to alibrate the touch in FB or X11 at: http://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi/touchscreen-install-and-calibrate

Interesting suggestion, but IMHO this is outside the scope of NOOBS. Closing as WontFix.

Unless you're able to provide your own patch that adds this...

Yeah looks like you need to integrate the calibration routines into the NOOBS GUI. You should be able to do this by detecting the touchscreen and running the calibration routine before running NOOBS...

Nice. If it works out-of-the-box that probably means that you have a more fancy controller that is emulating an USB input device.

Depending on which controller it is exactly, you may be able to teach it to return corrected values for you. E.g. for the AR1100 chip there is a calibration utility you can run under Windows and saves the results to the flash storage on the chip. The settings then apply for everything you use it with.
