Embedded development with a cross-platform IDE

CLion empowers embedded development teams to build, debug, and ship safe code faster, regardless of the target. It bridges the gap between general-purpose C, C++, Python, and Rust IDEs and highly specialized vendor tools, accelerating time to market while ensuring reliability in critical systems.

Embedded-ready by design

  • Out-of-the-box support for STM32, ESP32, RISC-V, AVR, PIC32, and custom GCC-based and IAR-based toolchains.
  • Seamless workflows with STM32CubeMX, ESP-IDF, PlatformIO, and Zephyr West.
  • On-chip debugging with ST-LINK, SEGGER J-Link, OpenOCD, and QEMU, plus RTOS and peripheral views.
  • Seamless remote development and on-target debugging for embedded Linux devices.

Accelerated development experience

  • No missed compile errors with smart formatting, linting, and error detection, including MISRA checks.
  • Full GoogleTest support and unit test automation for embedded code.
  • Remote development functionality with minimal latency, even on constrained setups.

Debugging for critical systems

  • Live watches: monitor variables in real time without halting execution.
  • RTOS awareness: see FreeRTOS, Azure, or Zephyr tasks and variables in context.
  • Peripheral views: load .svd files to watch hardware registers as you debug.
