Waveshare support for Raspberry Pi Operating Systems

A guide to adding touchscreen support for any Waveshare touchscreen display to various OSes.

This apparently works on any OS with a /boot/firmware/config.txt, or if the OS is very old, /boot/config.txt, but I have yet to check every single OS, for obvious reasons.

Options:

• Add dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900 to your /boot/firmware/config.txt file. credit

OR

• Use the below repository that will enable touchscreen and gestures on your RPi via terminal:
  • https://github.com/tobykurien/rpi_tablet_os

Tested OSes for adding to the /boot/config.txt:

• Ubuntu Touch
  • requires dtoverlay=disableoverscan
  • requires screen calibration
• Raspberry Pi OS
  • requires screen calibration
• Android 10 (Lineage 17.1) by KonstaKANG
  • no need to add, just uncomment line below #Waveshare touchscreen
  • requires screen calibration
• Android 9 (Lineage 16.0) by KonstaKANG
  • no need to add, just uncomment line below #Waveshare touchscreen
  • requires screen calibration
• RISC OS Pi

Tested OSes for the repo:

• Ubuntu

Theoretically Supported OSes:

• POP OS
• Ubuntu MATE
• Ultramarine Linux
• LibreELEC
• OpenELEC
• OSMC
• Recalbox
• RetroPie
• Kali Linux
