If you go this route, I would recommend starting off with the rp2040-hal crate and once you hit a pain point of managing multiple tasks, look into embassy or RTIC.

Rust and Cargo take the pain out of building and flashing to the RP2040 (or STM32, for that matter) - it's the most pleasant embedded setup I've ever used.
