Using all the work from @hfellner and others, add FreeRTOS SMP support. Allow idling cores through the FreeRTOS FIFO queue to allow for file system and EEPROM support. Make delay a weak function so FreeRTOS can override. Add cycle count support under FreeRTOS using a PIO SM. Use a task-based approach for handling the USB periodic work instead of the IRQ-based one in the main core. Set 8 prio levels so it fits in 3 bits nicely (0..7).

============
|
|
|
|
This is the documentation for the Raspberry Pi Pico Arduino core,
|
|
Arduino-Pico. Arduino-Pico is a community port of the RP2040
|
|
(Raspberry Pi Pico processor) to the Arduino ecosystem, intended
|
|
to make it easier and more fun to use and program the Raspberry Pi
|
|
Pico / RP2040 based boards.
|
|
|
|
This Arduino core uses a custom toolset with GCC 10.2 and Newlib 4.0.0
|
|
and doesn't require any system-installed prerequisites.
