This session will cover all of the main development platforms like Arduino, Circuit/Micro Python, Pico C++ and ESP-IDF when targeting a wide array of chipsets and boards including ATiny, ATmega, ATsamd, RP2040/2350, nRF52xxx and ESP32 board variants. Focusing on the core building blocks of chip based development, this overview will include tools, tips and techniques for making command line development both locally and over ssh as painless and as easy as using their graphical IDE counterparts. From debugging to flashing boot loaders, to updating helpful libraries. When all is said and done, you will better understand what the underpinnings of your favorite IDEs have been doing under the hood.
