3.5-inch display hardware.

We want to use the 3.5-inch display for something other than its intended purpose. We want to display QR-codes for payment. Can we program the display hardware ourselves to do this? What kind of microcontroller is used? Is the schematic available publicly?

Yes. Tedd.TuringScreen (https://github.com/tedd/Tedd.TuringScreen) or you can find other lib for python or nodejs on github.

Thank you. After your reply, I ordered one on AliExpress. I'll try using it for other purposes.
