I looked at it and dismissed it as too hacky for production. I don't remember the real reason why. I would have to look through my notes. The main question is whether the RP2350 will change that. As in it actually possible to do bug free without weird hacks.

Agreed. I re-wrote the Rx PIO routine to do a proper interrupt at EOF, and added a DMA driven ring buffer, which eliminated a lot of the hackiness...
