Phat Beat - Buttons and Lights not working

I’ve recently tried out the pirate radio project which turned out to be a bit of a faff, as the current versions of raspberry pi lite are not supported.

I eventually got it (sort of) working with a legacy version of Raspberry Pi OS Lite ( * Kernel version: 5.10

  • Debian version: 10 (buster)…but although it boots straight into radio and starts playing, none of the lights, nor the buttons work at all.

Is this fixable at all?
or should I start by running an older // more specific version of Raspbian Lite (e.g. I have a version of Raspbian Stretch Lite from April 2019).
