Hi people!
I've added my own touchscreen driver to the mou_touchscreen driver, and
even written my own kernel driver (since all touch data comes from a
slave processor via I2C).
It does work, but a single touch is not triggering the touch event in
Nano-X! I have to move around on the screen to make it trigger.
My driver does not "spit" data all the time or anything. Only when the
touchscreen is touched, it delivers X and Y and a touch event.
When moving your finger, it delivers the new X and Y data and a move
event.
And finally it delivers a untouch even when the finger has left.
All this comes from my /dev/touchscreen with a read of 3*32bits (x+y
+event).
When using a debug application which just read /dev/touchscreen and
print out all events + coords, it works perfectly and is fast.
But when using Nano-X it does not react on a touch until i move my
finger around.
It seems like it's dropping the first events!
Even when adding debug prints within the PD_Read, it all works great,
but it still doesn't make an GR_EVENT_TYPE_BUTTON_DOWN event!
I'm really lost here, so please help me get in the right direction to
fix this.
Best regards
Daniel
