Troubleshooting • Re: No touch on Adafruit 2.8" PiTFT Capacitive Touch screen

Ensure you are looking at the capacitive version of the display. Compare the bottom image on https://thepihut.com/products/adafruit- ... ouchscreen and https://thepihut.com/products/adafruit- ... ouchscreen, noting the chip built into the orange flexi cable going into the screen in each case.

Thanks for revisiting this and apologies for confusion on my end. It turns out that what I have is the resistive touch screen, see attached image, but a not-sufficiently-responsive one:

The touch screen now responds but not in any meaningful manner because 1) there is way too much latency (~1 sec) for it to be used with the pointer, 2) the touched position is is off by 180° relative to its displayed position anyway.

That is when set up with their script:
That's fine at this point as the four buttons are quite ok to use instead. The four buttons also give nice soft clicking tactile feedback when pressed.

Again thanks for revisiting this and clearing it up. Should I change the title of the thread to reflect the correct hardware?
