Discover the best Open Source RTOS solutions for embedded systems and IoT devices
InfiniEmu is a high-fidelity emulator for the PineTime smartwatch, simulating the nRF52832 SoC and its complete peripheral suite including I2C sensors and SPI displays. It enables developers to run production firmware like InfiniTime in both native desktop environments and web browsers using WebAssembly, featuring integrated support for FreeRTOS debugging and LittleFS storage.
A GNSS-based tracking application built on Zephyr RTOS that transmits location and ignition status over LoRaWAN using ABP authentication. It targets the ESP32 WROOM 32 and utilizes UART-based GNSS modules and Smart Modular LoRaWAN modems for cloud connectivity.
A comprehensive configuration guide and code repository for the HW-364A and HW-364B ESP8266 modules featuring integrated 0.96-inch OLED displays. It provides corrected I2C pin mappings, implementation examples using the U8g2 library, and specific Arduino IDE configuration settings to ensure reliable operation.
An open-source USB power meter based on the CH32V003 RISC-V microcontroller and INA219 sensor. It monitors voltage, current, and power (up to 100W/20V/5A) and displays data on a 0.96-inch OLED screen. The project features a compact design with PD 2.0 pass-through support and includes comprehensive hardware, firmware, and 3D enclosure files.
dtuGateway is an ESP32-based firmware that bridges Hoymiles HMS-series solar inverters with integrated Wi-Fi to smart home ecosystems. It provides reliable data monitoring and remote control via MQTT, REST API, and openHAB, bypassing the limitations of the official cloud interface. The project supports various local displays and features a captive portal for easy configuration.
This project provides a MicroPython port for the Flipper Zero, enabling native Python script execution on the device. It allows developers to interface with hardware components like GPIO, ADC, PWM, and the internal speaker using Python instead of C. The application is distributed as a Flipper Application Package (FAP) and integrates the standard MicroPython library.
A technical port of the Dexed FM synthesis engine to the Raspberry Pi Pico 2 (RP2350). The project utilizes the ARM Cortex-M33 cores to achieve 10-note polyphony at 44.1kHz, supporting I2S audio output and standalone MIDI tone playback.
An ESP32-S3 based platform that enables MDB protocol communication for vending machine cashless payments and remote telemetry. It features support for EVA DTS DEX/DDCMP standards, Bluetooth connectivity via NimBLE, and integrated foot traffic analysis using a PAX counter.
