Rainbow HAT

Hi, my Pi3 recently died so I bought a Pi4. I’m trying to run my Rainbow HAT HD but its not working properly. Some of the Pimoroni examples work, others dont. The library is installed correctly.

For some reason I’m getting various errors and the ‘C’ Touch button doesn’t work. Is there any reason a Pi4 GPIO is set up differently to a Pi3?

Thanks

As far as I know no. The Pi 5 has a fancy new GPIO controller but as far as I know the Pi 4 is same old, same old.
If you haven’t already, I would remove the hat and reinstall / reseat it on the Pi 4. And have another go.
The pinout is here,

I haven’t found a schematic though?
