Debugging

It Simply Works. Easier than ever before!

PlatformIO Debugging Solution offers a unique debugging experience for productive embedded development. Using our multi-board and multi-architecture programming experience, we simplified the debugging process in the same way. A zero debugging configuration with support for the most popular debugging probes and compatibility between IDEs and OS.

Developers can finally forget about complex UI windows which they need to pre-configure before a simple “Hello World!” debugging session. No need to know any aspects about the debugging server or how to configure it. PIO Unified Debugger does this complex work automatically having a rich configuration database per each board and debugging probe.

Just select a board, connect debugging probe (if a board does not have onboard debugging interface), specify it in PlatformIO project configuration file “platformio.ini”, and a project is ready for 1-Click debugging.

• “1-click” solution, zero configuration

• Support over 300+ embedded boards (see below)

• Multiple architectures and development platforms

• Windows, MacOS, Linux

• Built-in into PlatformIO IDE for VSCode

• Integration with Eclipse and Sublime Text

Hint
