raspberrypi/pico-sdk
Pico Sdk
The pico-sdk is a software development kit for creating C and C++ applications on RP2040 and RP2350 hardware platforms. It functions as an embedded development kit that provides hardware abstraction layers and drivers to interface with microcontroller peripherals and registers.
The project utilizes a CMake build system to manage the compilation of source code into multiple binary formats, including UF2, ELF, and HEX images. This environment coordinates the build and link processes to ensure the resulting firmware is correctly tailored for the target hardware.
The toolkit covers embedded hardware interfacing and network integration, allowing for the implementation of wireless communication protocols. It also includes tools for managing board-specific configurations, mapping software logic to physical pinouts and wireless hardware.
