Functions
void	setup1 (void) __attribute__((weak))
	Written by the sketch (optional): runs once on core 1, at the same time as setup() on core 0.
void	loop1 (void) __attribute__((weak))
	Written by the sketch (optional): runs over and over on core 1 after setup1().

Detailed Description

rp2040: the second core (setup1()/loop1()), the inter-core FIFO and chip information.

Same names as the arduino-pico core (Earle Philhower), so multicore sketches written for it also build here. Included by Arduino.h.

A sketch uses the second core by defining setup1() and loop1(); they run on core 1 at the same time as setup() and loop() on core 0. With Tools > Operating System > FreeRTOS they run as FreeRTOS tasks instead (setup()/loop() pinned to core 0, setup1()/loop1() to core 1). Design: docs/decisions/009-multicore-freertos.html
