Discover the best Open Source RTOS solutions for embedded systems and IoT devices
A custom-built 6-digit clock utilizing Soviet-era IV-11 vacuum fluorescent display tubes and an Arduino Nano Every. The project features a static drive architecture for maximum brightness, integrated power conversion for high-voltage rails, and a robust finite state machine for user configuration and timekeeping.
M5_Crystal is a modular firmware for M5Stack devices like the M5StickCPlus2 and Cardputer, providing a suite of tools for Wi-Fi, NFC, and Bluetooth interaction. It utilizes the M5Unified and M5GFX libraries for hardware abstraction and is built on a custom wrapper system designed for rapid feature development.
A full-stack embedded Linux project for the NXP i.MX 8M Plus EVK featuring real-time NPU-accelerated object detection and NIR spectral monitoring. It demonstrates a complete development workflow from Yocto BSP bring-up and custom kernel module development to high-level Python applications using TensorFlow Lite and GStreamer.
This project details the reverse engineering and firmware development for repurposing a YOJOCK/Kowsi USB-C multimeter as a PY32F002A development board. It features a custom firmware implementation that provides power sensing, a stopwatch, and games, leveraging a bit-banged SPI interface for its 160x180 color display.
Clawdmeter is an ESP32-S3-powered desk dashboard that monitors Claude Code token usage and displays it on a 2.16" AMOLED screen. It uses the LVGL library for its high-resolution UI and the NimBLE stack to communicate with a host daemon via BLE, while also functioning as a HID keyboard for shortcuts. The project features dynamic pixel-art animations that react to real-time API utilization rates.
An ESP32-based bridge that interfaces CAN bus systems with IoT environments using the Lawicel (SLCAN) protocol. It supports real-time CAN data monitoring and transmission via a web interface, Serial, or WebSockets, and is designed for automotive and industrial applications.
An interactive virtual pet built with Rust on the ESP32-C3, featuring environmental sensing and a state-driven animation system. It utilizes DHT and LDR sensors for environmental awareness and NVS for persistent statistics.
A wireless e-ink device based on the ESP32-powered Soldered Inkplate 6 platform that displays meeting room schedules. It utilizes the Roombelt backend for data and features a secondary digital photo frame mode that reads images from a microSD card.
