smolOS (pronounced small OS) is an open-source, lightweight MicroPython program that implements a POSIX-style (Linux-like) command line interface for the ESP8266 WiFi microcontroller.
Krzysztof Jankowski (w84death) designed smolOS to be easy to use, allowing the listing and removing of files and also including the smolEDitor which, as its name implies, is a simple text editor.
There are currently eight commands with the familiar ls, cat, and rm, plus ed to launch the text editor, welcome to show the welcome screen above, cls to clear the screen, mhz to set the processor speed to 80 or 160 MHz, and info to display some hardware and software information.
The project looks to be a work in progress, and the developer highlights the editor is at the alpha stage of development, so more features may be implemented over time by Krzysztof himself or by the community of developers. I also assume other microcontrollers could be supported relatively easily, especially the ESP32 family.
You’ll find the source code and instructions to flash MicroPython and load smolOS’s main.py program (currently 186 lines of code, 7.07KB in size) to an ESP8266 board on GitHub.
