Hi all, I inserted this cheap TFT Touch screen into the Due R3 and so far all graphics samples that I ran from MCUFriend_kbv work fine, except for the touch.
The diagnose touch pins sample does not report the pins, the output is:
Making all control and bus pins INPUT_PULLUP
Typical 30k Analog pullup with corresponding pin
would read low when digital is written LOW
e.g. reads ~25 for 300R X direction
e.g. reads ~30 for 500R Y direction
The way I inserted the display on the Arduino was by lining up the 3v3, 5v and Gnd pins with the arduino corresponding pins thus the graphics samples run just fine, but can't figure out what kind of mapping needs to be done and how to map it to get the touch working, any help is appreciated.
