eLua (Embedded Lua) aims to introduce the programming language Lua to the embedded software development world. Lua is the perfect example of a minimal yet fully functional language. The aim of the project is to have a fully functional Lua development environment on a microcontroller (Lua interpreter, modules appropriate for microcontroller environments, and editor) without the need to install a specific toolchain on the PC side.
OpenSCB is a hardware and software solution for controlling servos over USB. The hardware is designed to interface with classic RC servos, AX-12/AX-18 servos, OpenServo, and more using a powerful 32-bit microcontroller with a USB port for programming and control with a PC. The schematic and layout will be available and can be customized. A graphical interface is also provided for your computer to configure, calibrate, and control the board.
fpgatools is a toolchain for programming flexible programmable gate arrays (FPGAs). The only supported chip at this time is the xc6slx9, a cheap (circa $10 U.S.) but powerful 45nm-generation chip with about 2400 LUTs, block ram, and multiply-accumulate devices. The principles of fpgatools are to reach the maximum physical performance of the chip, to provide fast development cycles, to be an independent toolchain which only depends on other Free Software, and to be a lightweight C implementation without a GUI.
