Raspberry Pi Zero 2 On PicoCalc

PicoCalc
, ,
160

I think I may followed the wrong GitHub? https://github.com/wasdwasd0105/picocalc-pi-zero-2?tab=readme-ov-file#guide-for-setup-pi-zero-2-on-picocalc

After installing the driver using

cd ./picocalc-pi-zero-2
chmod +x ./setup_display.sh
sudo ./setup_display.sh

I got this

After/during keyboard driver installation using

cd ./picocalc-pi-zero-2
chmod +x ./setup_keyboard.sh
sudo ./setup_keyboard.sh

I got this:

And when trying to do the last step: Edit /boot/config.txt (with sudo) and add:

I got this

dtparam=i2c_arm=on
dtoverlay=picocalc_kbd
DO NOT EDIT THIS FILE

The file you are looking for has moved to /boot/firmware/config.txt

(which I then modified the /boot/firmware/config.txt)

But I don’t see anything on the screen
