XIAO RP2040, RP2040 SDK and APIs

New release of Earle F. Philhower Arduino “core” for RP2040 … version 2.0.0 and … :smiley:

Version 2.0.0 adds FreeRTOS SMP support thanks to @hfellner.

Normal applications will still use the default, non-RTOS setup/loop and setup1/loop1, but for users who need preemptive multitasking and multiple threads, FreeRTOS SMP can be used with
a simple #include <FreeRTOS.h>
