Open Source C User Interface (UI) Software for Embedded Operating Systems

An extensive and multi-platform visualisation, process control and HMI application that supports many different devices via an open plug-in interface. Beside a visual GUI editor a debugger is part of the package.

This project is a GPLed OSS project, which is developed and maintained by Feynman Software. It aims to provide a fast, stable, lightweight, and cross-platform Graphics User Interface support system, which is especially fit for real-time embedded systems.

CLIck allows you to create flat or hierarchical CLI (command line interfaces) in an extremely easy and quick way, supporting very popular features like history with command recalling, context-based auto-completion, tab-based command list, automatic command-line help, special characters, automatic structure builder, and much more. CLIck is written in ANSI C and tested on C and C++ applications on several architectures. It doesn't depend on any external library and uses only a very small subset of POSIX APIs. Despite the project name, you won't need your mouse at all!

PW is a small graphics and windowing library. It was designed especially for small embedded systems using 1 bit graphic LCDs. It is very portable, written in ANSI-C and has a small memory footprint.

PocketFrog is *THE* game library to rapidly write blazing fast games on the Pocket PC platform. It is implemented in C++ with an object oriented design. If your application needs to harness the raw power of your Pocket PC graphics, PocketFrog is for you.

Shell Script Menu gives shell scripters a way to give users real menus instead of just text fields with options that are typed in.

MTK is a minimalist toolkit for LPC24xx development boards with QVGA displays with touchscreen. It uses standard linux framebuffer and has double buffered system to prevent flickering.

Synthesia is an open hardware/software platform intended for creating standalone audio devices such as synthesizers on embedded processors.
