Please fix LCD35C-show. Has not been updated in 4 years and doesn't work.

goodtft/LCD-show does work but unfortunately they don't have the LCD3.5C variant and the touch doesn't work. The official driver doesn't work at all. Please fix products which you sell. no point selling it if you are not going to actually support it and maintain it.

LCD35-show of goodtft/LCD-show does work for my 3.5C, both for display and touch. (RPi4, bullseye 64bit)

[JimJ92120]

got it running on Pi 4B with kernel 6.1 on bullseye and bookworm (Raspberry PI OS 64-bit version) following [waveshare wiki instructions] (https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(C)#Install_the_touch_driver)
(example for C version)

also assuming x-org is used (and not wayland on bookworm)

following must be run with root privilege:

./LCD35C-show

# now
sudo  ./LCD35C-show

then updating (or creating) /usr/share/X11/xorg.conf.d/99-fbdev.conf as mentioned here:

  # output to LCD screen
  Option "fbdev" "/dev/fb1"

  # or replace with this to output to HDMI instead
  Option "fbdev" "/dev/fb0"
