Raspberry Pi Pico SDK

What Raspberry Pi Pico SDK is

Raspberry Pi Pico SDK provides the headers, libraries, and build system for writing C, C++, or assembly software for RP-series microcontrollers. Its C-level APIs expose hardware features including Programmable I/O, while higher-level libraries cover timers, synchronization, Wi-Fi and Bluetooth networking, USB, and multicore programming. The SDK can support applications, runtime environments such as MicroPython, and low-level software such as the on-chip bootrom. It targets RP2040 Arm Cortex-M0+ and RP2350 Arm Cortex-M33 and Hazard3 RISC-V devices. The quick-start workflow uses CMake and requires Python 3, a native compiler, and a GCC cross compiler. Developers can work from the command line or use Visual Studio Code or CLion. Raspberry Pi’s VS Code extension adds project generation, CMake setup, version switching, and one-click compilation and debugging; it also supports MicroPython through MicroPico and project work with Rust and Zephyr. The SDK is open source under BSD-3-Clause and is free for Windows, macOS, and Linux.
