Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools using debug_tool options.

On-Board tools

Boards listed below have on-board debugging tools and ARE READY for debugging! You do not need to use/buy external debugger.
