Kivy touch events not working on Raspberry PI with Adafruit PiTFT

Hi!

I have an Adafruit 2.8in LCD with a resistive touchscreen [1], connected to a Raspberry Pi and working with Kivy. I have had to use fbcp [2] to get this setup to work with Kivy, but that is fine. While I have seen issues with idle apps using 30-40% CPU (as per htop), the primary blocker in my setup is that the touchscreen errors out with Kivy.

I can create a Button in a Kivy App and press it, Kivy does see the touch, but errors out:

[INFO              ] [HIDMotionEvent] using <stmpe-ts>
 Exception in thread Thread-1:
 Traceback (most recent call last):
   File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
     self.run()
   File "/usr/lib/python2.7/threading.py", line 505, in run
     self.__target(*self.__args, **self.__kwargs)
   File "/home/pi/kivy/kivy/input/providers/hidinput.py", line 580, in _thread_run
     process_as_mouse_or_keyboard(*infos)
   File "/home/pi/kivy/kivy/input/providers/hidinput.py", line 456, in process_as_mouse_or_keyboard
   l = keyboard_keys[ev_code][-1 if 'shift' in Window._modifiers else 0]
 KeyError: 330

Here are a few additional notes:

• After this, I am unable to get another button press to register in the log, but the app is still running and updating the screen.
• The above errors were seen with kKivy installed from git master from a few days ago, I will update to latest master and retry.
• I can debug, build, etc, specific branches, patches, etc… anything to help this move along.

It finally works for @illumin-us-r3v0lution. As he said on irc:

<luminous> param=rotation=270,param=invert_y=1 <luminous> ,param=rotation=90,param=invert_x=1

Both works. Let’s merge into master!

@tito I am facing issue even displaying anything on the touchscreen. The screen is calibrated (I don’t use X either). Event test works (ts_test & evtest). Please let me know how to display the UI on touch display instead of HDMI. (I have tried the usual methods FRAMEBUFFER variable & DISPLAY variable)
