README.md

A quick guide on how to install a (3.5) waveshare(/clone) LCD on a Raspberry Pi running 64bit OS (namely Raspbian). Guide is written for 3.5 inch screen but could be adapted for any screen.

Installation

git clone https://github.com/tux1c/wavesharelcd-64bit-rpi.git

cd wavesharelcd-64bit-rpi

chmod +x install.sh

sudo bash install.sh

Troubleshooting

White screen on boot (raspberry pi boots)

make sure dtoverlay=vc4-fkms-v3d is NOT present / commented out in /boot/config.txt

Adapting for other LCDs

  1. clone https://github.com/swkim01/waveshare-dtoverlays
  2. compile on the raspberry pi running 64bit OS the desired overlay: dtc -I dts -O dtb -f waveshareXYZ.dts -o waveshareXYZ.dtbo
  3. copy the output file to /boot/overlays
  4. grab calibration file (99-calibration...) from https://github.com/goodtft/LCD-show and place in /etc/X11/xorg.conf.d/99-calibration.conf
