RP2040 and RP2350

Modules with a the same API for both RPs.

Overview

The modules’ API may be implemented in a different module for each MCU.

Repository:
+ libv2
  + mcu
    + rpi
      + any     <= common API, common implementation
      + rp2040  <= common API, RP2040-specific implementation
      + rp2350  <= common API, RP2350-specific implementation

Modules tagged with libv2 have been ported to using the Oberon RTK framework v2.
