Vi,

I just added a 3.5” display with touch to my Rpi 2B+, runs smoothly with 59 fps

One instrument is indeed no problem for the Pi :)

Nice. I was thinking of doing something similar a while back but headed in a different direction. Can you post the display details and confirm that the touch is working as expected?

Hi,

The display is Adafruit 3.5” with resistive touch, its the older version with 2x13 pins.

The installation was really easy, started with AirManager image and then followed the instruktions on adafruit.

The touch funktion is a bit erreanous now, I will try to do a calibration as I rotated the image 180 degrees, the touch funktion is working but the precision is not that accurate.
