rp2040-pico
Firmware development for the Raspberry Pi Pico (original, RP2040 — dual Cortex-M0+ @ 133 MHz, 264 KB SRAM, 2 MB QSPI flash) — its 26 exposed GPIO, 4-channel 12-bit ADC, 16-channel PWM, 2× UART/I2C/SPI, PIO state machines, USB 1.1 CDC, VSYS/VBUS/SMPS power wiring, and the PlatformIO + arduino-pico (earlephilhower) setup around them. Use when working on this board, any Pico H or Pico clone, or a bare RP2040: project setup, platformio.ini, the earlephilhower-vs-Mbed core choice, pin mapping, USB CDC serial, analogRead/analogWrite behaviour, Wire/SPI defaults, battery power, EEPROM emulation, BOOTSEL/UF2 flashing, or debugging why something on the board does not work.

# Raspberry Pi Pico (RP2040)
Board-specific firmware knowledge. The Pico's failure modes are quiet: a
wrong `platformio.ini` line silently links a different Arduino core, `Serial`
goes to a port that does not exist yet, and an ADC pin doubles as a power
rail — so read the reference files rather than guessing.
- `reference/board-hardware.md` — the complete board reference: 40-pin map
with alt functions, the four hidden GPIOs, power tree, clocks, memory map,
relevant errata **plus** a development guide (Part II: §7 toolchain and
the core-choice table, §8 peripheral cookbook, §9 flashing, §10
symptom → cause → fix table).
- `reference/recipes.md` — copy-paste code: `platformio.ini`, `board.h`
excerpts, USB CDC + Serial1, ADC with the VSYS ×3 math, PWM and the slice
