KernelUNO – A lightweight OS for Arduino UNO with a Linux-like shell

KernelUNO is an Arduino sketch with 546 lines of code that provides a lightweight OS for the Arduino UNO with a Linux-like shell offering commands such as ls, df, uname, and so on. All you need is an Arduino UNO R3 or a compatible board with a Microchip ATmega328P microcontroller, a USB cable for programming, and optionally a few LEDs and resistors for testing the gpio command in the terminal. KernelUNO offers the following features: Virtual Filesystem – Create files and directories in RAM (/dev, /home) Hardware Control – GPIO management with pin mode configuration System Monitoring – Memory usage, uptime, kernel messages (dmesg) Interactive Shell – Real-time command execution with input buffering 23 built-in commands File system commands – ls, cd, pwd, mkdir, touch, cat, echo [text] > [file], rm, info [name] Hardware commands pinmode [pin] [in/out] – Set pin mode write [pin] [high/low] – Write to pin read […]
