The ESP32 microcontroller supports in-circuit debugging, i.e. your code can be run on real hardware while stepping through it line by line, running to the next breakpoint, inspecting variables etc. These instructions help you set up debugging, both for Arduino and ESP-IDF projects. Unfortunately, E…
