Discover the best Open Source RTOS solutions for embedded systems and IoT devices
PicoSound is a dual-core audio engine for the Raspberry Pi Pico (RP2040) that offloads audio processing to Core1 to ensure glitch-free playback. It supports an 8-channel mixer, synthesized waveforms, and WAV file streaming via LittleFS or PROGMEM, targeting both Arduino IDE and PlatformIO environments.
FOC_Pocket is a compact, coin-sized brushless motor controller based on the ESP32-S3 and the SimpleFOC library. It utilizes highly integrated MPS chips, including the MP6541A driver and MA600A magnetic encoder, to provide precise position, speed, and torque control for small gimbal motors.
This project implements a Recurrent Neural Network (RNN) on an ATtiny85 microcontroller to perform MNIST digit recognition with approximately 95% accuracy. It utilizes the device's internal 512-byte EEPROM to store quantized model weights and biases, enabling deep learning inference on a highly resource-constrained 8-bit platform.
A custom-built portable MP3 player based on the ESP32 that features Bluetooth A2DP audio streaming and a dedicated OLED user interface. It utilizes a modular C++ architecture and a custom-designed PCB to manage media playback from a MicroSD card.
A tile-based firmware for ESP32-P4 devices that creates a touch-first Home Assistant dashboard. It utilizes FreeRTOS and LVGL for the user interface, supporting MQTT integration and web-based configuration. The system targets ESP32-P4 hardware like the Waveshare B4 and M5Stack Tab5, featuring OTA updates and internal storage management via LittleFS.
An open-source AWD controller for Volkswagen and Audi Group vehicles using Haldex Generation 1, 2, 4, and 5 differentials. Built on the ESP32-C6, it utilizes dual CAN interfaces to intercept and modify vehicle signals, enabling custom torque distribution, standalone operation, and wireless tuning via a web interface.
An open-source avionics stack for FPV drones featuring a custom STM32F411 flight computer and an STM32F405 power distribution board. The project includes full KiCad 9.0 hardware designs, STM32 HAL-based firmware, and a robust 3D-printable airframe optimized for 935 KV brushless motors.
FPBInject is a runtime code injection tool for ARM Cortex-M microcontrollers that allows developers to replace functions on a running device without reflashing, rebooting, or using a debugger. It leverages the hardware Flash Patch and Breakpoint (FPB) unit to redirect execution to custom code in RAM, supporting both bare-metal and NuttX environments on STM32F103 hardware.
