I picked up one of these
and following these instructions gets both the screen and touch input working on raspbian
I tried following those same instructions on Balena OS to no avail. The LCD works fine but not the touch controller.
1.) copying the goodix-7-acme.dtbo file into the boot/overlays folder
2.) Adding these lines to config.txt
# Activates the I2C 1 port on GPIO44 and 45 to talk with the # touch screen controller end camera crypto-chip dtoverlay=i2c1-bcm2708,sda1_pin=44,scl1_pin=45,pin_func=6 dtoverlay=goodix-7-acme
…but the touch input isn’t working. Even looking in /dev/input shows nothing other than “mouse” and lsmod doesn’t show anything relating to the Goodix touch input driver. Any ideas on what I should do to get this working?
