PicoGUI aims to be a complete GUI environment for handheld computers and other embedded systems. It uses a client/server model, like the X window system, but while an X server is given raw drawing commands, the PicoGUI server integrates a widget set, making PicoGUI clients small and efficient. PicoGUI also has the goal of allowing client/server connections over a variety of mechanisms. It is most commonly used with Linux, but is designed to be portable to any OS. PicoGUI has a variety of video and input drivers which allow it to interface with the Linux framebuffer device, SDL, the X window system, and several other devices.
The rcpod (Remote Controlled PIC of Doom) project is based on firmware for the PIC16C745 or PIC16C765 microcontrollers that executes I/O operations on behalf of the USB host. Included are libraries for C and Python programs to access the rcpod device, PCB layouts for rcpod devices, and example programs. It currently supports basic general-purpose I/O, pulse-width modulation, synchronous and asynchronous serial, and RS-485.
Nouvelle is a very simple Web rendering framework, similar to the 'nevow' package in Quotient but with a few key differences. XHTML documents are constructed using a convenient pure-Python syntax. Nouvelle itself doesn't require a particular web server or environment, but it can interoperate with Twisted or BaseHTTPServer easily.
Inputpipe is a client/server application for making any Linux input device network-transparent. An inputpipe client runs on a computer with some arbitrary input devices, forwarding information and status from those devices to an inputpipe server. The server creates local input devices that are identical copies of the devices being forwarded for all practical purposes.
