What it is

Raspberry Pi Pico SDK is a free, BSD-3-Clause software development kit for writing C, C++, or assembly programs for RP-series microcontrollers. It supplies headers, hardware APIs, libraries, and a CMake build system, including access to Programmable I/O. Higher-level libraries cover timers, synchronization, Wi-Fi and Bluetooth networking, USB, and multicore programming. The SDK targets RP2040 Arm Cortex-M0+ and RP2350 Arm Cortex-M33 and Hazard3 RISC-V devices. It can support simple applications, MicroPython runtime environments, and low-level software such as an on-chip bootrom. Quick-start instructions use CMake, Python 3, a native compiler, and a GCC cross compiler. Work is possible from the command line, Visual Studio Code, or CLion. Raspberry Pi’s VS Code extension adds project generation, CMake setup, version switching, compilation, and debugging. It supports Windows, macOS, and Linux, with documentation for SDK APIs and Pico W connectivity.
