Well this rang the ol’ memory bells and brought me to Daniel’s Nim drivers for our Pico based products (1). He’s probably the guy to talk to. Not needing a Python wrapper would definitely help slim down FrameOS into something you could stuff into a fast-loading initrd I guess? I did something similar with Keybow, static binaries and a custom build system (2) to make a sort-of Pi (Zero) based appliance. 1. https://github.com/daniel-j/nim-pimoroni-pico/tree/master 2. https://github.com/ali1234/rpi-ramdisk

I have written drivers for Pimoroni's Inky Frames (based on Raspberry Pi Pico W) in Nim, but I don't own an Inky Impression. The code should be pretty similar once it hits the SPI bus. https://github.com/daniel-j/nim-pimoroni-pico/blob/master/sr... I have planned to write GPIO/SPI/I2C "drivers" in Nim that interfaces with the Linux drivers. So far I have made a wrapper for libgpiod. https://github.com/daniel-j/nim-gpiod
