Open-BLDC is firmware for STM32 microcontroller based brushless motor controllers. The goal of the project is to support active freewheeling, active break, adjustable timings, rotation speed and power controllers, and many more. Support for multiple interfaces like PPM, RS232, I2C, and CAN is planned.
UniMote server is a universal Android-to-Linux Bluetooth remote controller for multimedia applications. It is fast and stable. It supports easy-to-develop plugins. For now, plugins for controlling these applications are available: XBMC, Clementine, VLC, and file browser. More plugins will be added as soon as the core is stable.
WIRN is a professional stored program control. It is optimized for heat control, but you can control whatever you want. It is a multitasking system using FreeRTOS.org on Atmel AT32UC3A1512, and has an API for simple sensor/actor interaction that makes it modular and simple to extend. Also included is a triac control over AVR ATtiny2313 and a 1Wire Interface. You can extend it via software: implement your own control loop with some lines of C code. You don't need a compiler; upload your code and get a binary back. Flash this binary over USB and go. It also has 3 ports to plug in your own hardware.
