Open Source C HMI Software

Snap7, through three specialized components: Client and the inedited Server and Partner, allows you to definitively integrate your PC based systems into a PLC automation chain. Designed to transfer large amounts of hi-speed data in industrial facilities, it scales easily, down to small Linux Arm boards such as Raspberry PI. Hi level object oriented wrappers are provided, currently C/C++, .NET/Mono, Pascal, LabVIEW, Python with many source code examples. Very easy to use, a full working server example is not bigger than the “Hello world”. Many projects/makefiles are ready to run to easily rebuild Snap7 in any platform without the need of be a C++ guru. Very detailed documentation provided.

Florence is an extensible scalable on-screen virtual keyboard for GNOME that stays out of your way when not needed. You need it if you can't use a real keyboard either because of a handicap, broken keyboard or tablet PC but you can use a pointing devide.

Presage (formerly Soothsayer) is an intelligent predictive text entry system. Presage generates predictions by modelling natural language as a combination of redundant information sources. Presage computes probabilities for words which are most likely to be entered next by merging predictions generated by the different predictive algorithms. Presage's modular and extensible architecture allows its language model to be extended and customized to utilize statistical, syntactic, and semantic predictive algorithms. Presage's predictive capabilities are implemented by predictive plugins. Predictive plugins use services provided by the platform to implement multiple prediction techniques.

The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.

reacTIVision is a computer vision framework for the fast and robust tracking of markers attached on physical objects, and the creation of multi-touch surfaces. It was designed for the rapid development of table-based tangible user interfaces.

The Augmented Reality Tool Kit (ARToolKit) captures images from video sources, optically tracks markers in the images, and composites them with computer-generated content using OpenGL. Dual-licensed, under the GPL, plus commercially by ARToolworks, Inc. NEW: A free demonstration of ARToolKit capabilities has been made available as part of ARToolworks "Codex Interactivus: Bringing Leonardo to Life!" Kickstarter project. Download from https://www.kickstarter.com/projects/artoolworks/codex-interactivus-bringing-leonardo-to-life/

Working hardware has been built and is in a late beta stage. Software is also available.

TinyOS is an operating system for embedded sensors and networks. Versions 2.0 and later of TinyOS should be downloaded from www.tinyos.net.

Winboard 4.5 32-bit is a free Windows accessible Chess program that works automatically with the JAWS or the free NVDA screen reader. It is for the blind, low sighted or those who can not use a mouse. It provides vocal announcements of position changes and other selectable board conditions. Blind players also use a separate "tactile chess board". Winboard 4.5 has full keyboard access to move pieces and run menu items. Partial sighted players use high contrast mode and adjust board, piece, most font sizes and colors. Available languages are English, German, Spanish, Italian, Dutch and Russian. Games may be viewed, modified or saved in standard PGN format. Two Chess engines supply play and grand master strength move analysis. Connect to the Free Internet Chess Server (FICS) and play humans. Modify verbosity in screen reader configurations and in the Winboard "Sound" dialog under the "General" menu. Find all documentation in the "doc" folder under the Winboard directory of your C drive.

The Ground Station Software Suite projects aims at providing free, useful software tools for ham radio operators. Currently, this projects hosts the Grig communication radio control. The source repository has been moved over to github.

BEYE (Binary EYE) is a free, portable, advanced file viewer with built-in editor for binary, hexadecimal and disassembler modes. It contains a highlight AVR/Java/i86-AMD64/ARM-XScale/PPC-64 and other disassembler, full preview of MZ,NE,PE,ELF and other.

MegaTunix is a cross-platform tuning application for some of the available DIY Fuel Injection controllers, including the MegaSquirt (MS1, MS1-Extra, MS2 and MS2-Extra) as well as the LibreEMS EFI system and the JimStim ECU stimulator/development tool.

libVISCA is a library for controlling a VISCA compliant video camera. VISCA is a professional camera control protocol, designed by Sony to be used on several of its surveillance and OEM block cameras.

Coriander is a full-featured GUI for IEEE1394, IIDC-compliant digital cameras.

FreeSOLID is a library for collision detection of three-dimensional objects undergoing rigid motion and deformation. FreeSOLID is designed to be used in interactive 3D graphics applications.

Converts bitmap file to c/c++ files (usefull for embedded systems with GUI). The color encoding is fully configurable (for example 16bit 5/6/5) and a "preview" bmp file is generated to show how much the picture is altered by the information reduction

This is a non-official driver, written in C, for the FPS200 Veridicom's fingerprint sensor with the USB interface. It is also compatible with the Fujitsu's MBF200 fingerprint capture device.

Development of Linux kernel drivers and userspace libraries to take advantage of the tactile feedback capabilities of the Logitech iFeel mouse.

Zmeter is an RS232 serial interface program for the RadioShack 22812 (46 range) Digital Multi Meter (DMM). Zmeter captures the DMM display and outputs it in ASCII text to stdout.

Ccide reads a source program, in one of several programming languages, expands all embedded decision tables, and generates the new, expanded source. Ccidew processes C language programs directly. The script, ccide, uses ccidew and m4, to process BASIC, JAVA, CC, C++, BASH, QB, VB, and EX(euphoria), source files containing embedded decision tables. Ccide checks all conditions once and only once, avoiding side effects. Ccide checks tables for conflicts and other errors. Input example: //DECISION_TABLE: // 1 3 2 2 | light == $$ /* 1=red, 2= yellow, 3=green. */ // N - - - | speed == STOPPED // - - Y - | speed == SLOW // - N - Y | speed == FAST // ______|___________________ // X - X - | Stop(); // - - - X | SlowDown(); // - X - - | SpeedUp(); //END_TABLE:

Fingerprint Verification System; an easy to use library that allows programmers to integrate fingerprint technology into their software without specific know-how. Fast, easy to use, and small; great for embedded systems.

ChNIDAQ allows user programs to use the NI-DAQ C library and run interpretively without compilation. It is an ideal solution for teaching and learning data acquisition, prototyping, and web-based remote data acquisition.
