Advanced STM32 debugging in VS Code
29 May 2026
Design Automation
Debugging embedded systems gets harder as projects grow. At some point, breakpoints and variable windows stop being enough. Designers need to see how their application behaves over time, track down bugs, inspect registers in context, and measure what the code is really doing.
ST now allows designers to do all of that if STM32 projects are being built in VS Code. STM32Cube for VS Code brings together C/C++ editing, CMake and Ninja builds, Git, and one-click debugging.
Once an STM32 project is running in VS Code, the IAR C-SPY Debug extension adds a professional-grade analysis layer that scales with project complexity.
IAR C-SPY goes beyond breakpoints and variable inspection, providing a live, spreadsheet-like view of your running target, including:
• Core registers and custom register groups.
• Symbolic memory with direct variable navigation.
• Live Watch.
• ETM/SWO trace.
• Functional profiling.
• Real-time code coverage.
Together, STM32Cube for VS Code provides a fast entry point into the STM32 ecosystem, and IAR adds deterministic builds, advanced trace, and deeper analysis for projects that need more visibility.
