Discover the best Open Source RTOS solutions for embedded systems and IoT devices
A Raspberry Pi Pico-based signal converter that translates legacy TTL video signals (MDA, CGA, and EGA) into modern VGA output at 720x400 @ 70Hz. It leverages the RP2040's PIO state machines and DMA for high-speed pixel capture and signal generation, supporting various legacy resolutions and frequencies.
A 3D-printed, 18-servo hexapod robot platform designed for agility and flexibility, supporting both ESP32 and Raspberry Pi Pico controllers. The project features WiFi-enabled remote control via UDP, Over-the-Air (OTA) firmware updates, and a modular mechanical design optimized for 3D printing.
An open-source monitoring and control solution for Victron Multiplus II systems using the LilyGo T-Display S3 AMOLED. Built on the ESP32 platform, it provides real-time data on solar power, grid status, and battery health while allowing users to toggle charger and inverter functions.
A library for building advanced keyboard firmware that uses the Nickel configuration language to define complex keymap behaviors. It supports Rust-based firmware using the RTIC and Embassy frameworks, as well as C-based firmware for WCH RISC-V microcontrollers. The project enables sophisticated features like layers, tap-hold keys, and chords across various hardware platforms including RP2040, STM32F4, and CH32X.
A multi-platform Commodore 64 emulator designed for ESP32-S3 and ESP32 microcontrollers, supporting various display technologies from integrated LCDs to LED matrix panels. It utilizes FreeRTOS for multi-core task distribution and offers versatile input options including custom Android BLE and web-based keyboards.
An automated solar concentrator system that uses an ESP32-CAM and Arduino Pro Mini to focus sunlight onto a thermal target. It utilizes the ESP-IDF framework and FreeRTOS for computer-vision-based sun tracking and mirror orientation.
A versatile C++ library for the QN8066 FM transceiver, enabling high-quality FM radio transmission and reception with RDS support. It targets a broad range of Arduino-compatible hardware including ATmega328, ESP32, STM32, and ATtiny, providing low-level I2C control and high-level functional abstraction.
A ROS 2 bridge for controlling Xiaomi Cybergear motors using M5Stack hardware via micro-ROS and Ethernet. The system supports multiple motor configurations, real-time control modes, and parameter tuning through standard ROS 2 interfaces.
