Advanced Debugger for Arduino

This article describes improved version of our source-level debugger for Arduino. The can be used to debug Arduino programs using GNU GDB with Eclipse or Visual Studio Code as the visual front-end. It supports all functionally expected from a such stepping through code, setting breakpoints, viewing and modifying variables. These features are otherwise not available popular AVR-based boards without an external probe modification board. With presented it is only needed add program library user optionally replace bootloader. speed up development make platform even more usable tool controlling various experimental apparatus teaching computer programming. focuses on new improvements we made in since its introduction 2016. most important improvement over old support inserting breakpoints into memory which allows debugging affecting debugged interrupt service routines. Further enhancements include loading via newly added Mega boards.
