Moving to a RTOS on the RP2040

As projects get more complicated the tooling has to improve. Outgrowing the arduino-ide is easy on the Pi Pico with the excelent pico-sdk but what if things get even more complicated...

The FreeRTOS also doesn't seem to provide any hardware abstraction at all which means all the code I wrote to communicate with the various chips is not easily re-used. After a few days I created a new clean FreeRTOS project and started porting the various functionalities from the previous version over to try to get a cleaner and more manageable codebase but ended up giving up because blind debugging because there's no serial output is quite annoying. Yeah no thanks, I have already several perfectly fine ARM toolchains and I don't really want to either build or fetch precompiled compilers for every architecture Zephyr supports, lets see if I can get away with not installing this.
