IAR Embedded Workbench vs Raspberry Pi Pico SDK

IAR Embedded Workbench is an embedded development toolchain with an IDE, optimizing compiler, linker, assembler, and debugger. It supports over 20 architectures, including Arm, RISC-V, 8051, MSP430, AVR, and several Renesas families. The C-SPY debugger provides real-time trace, code coverage, function profiling, and RTOS awareness. IAR C-STAT offers static analysis; IAR C-RUN detects runtime errors and is available for Arm and RX. The toolchain works with VS Code and Eclipse, supports CMake builds, and can integrate with CI/CD pipelines. Supported debug probes include I-jet, I-jet Trace, J-Link, PE Micro, and ST-LINK. Built-in plugins provide RTOS awareness for systems including PX5 RTOS and Zephyr RTOS. The IDE runs natively on Linux and Windows. A 14-day evaluation is available for non-commercial use, but excludes runtime library source code, C-STAT, and MISRA C support and includes limited technical support. Paid subscription pricing is available by request; the subscription combines named-user licenses and build capacity for automated builds and CI/CD.

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.
