Open Source C Simulation Software

- - - T H I S P R O J E C T M O V E D T O G I T H U B - - - A framework for the implementation of advanced real-time control systems which uses signal/block-based schematics (like Simulink) extended by several features like state machines and online-exchangeable sub-simulations. Besides, this framework properly handles multiple threads, their communication, allows to synchronise control systems to external events (e.g. variable timers or incoming network packages) and provides many other nice features. Because of a high-level schematic-description language -- in form of provided Scilab commands -- only a minimal implementation-effort (no error-prone C-programming) is required.

Experix is a command-line driven environment for laboratory data acquisition and device control and graphical presentation and analysis of data. Written in C for GNU-Linux . Tested on PC and Raspberry Pi. The core is written very generally in order to support applications by means of script files. Device interfaces: PCMCIA daq (2 devices tested) via kernel module with interrupt handler and memory-mapped data; USB daq (1 device tested) using libusbx; running an equipment servicing program via pipes. Interfaces accessible via commands and scripts: file i/o modelled on stdio and stdlib; usb control and bulk transfers; socket operations; webcam; graphics via framebuffer. Applications (not all available yet for download) include: cell poker (like an atomic force microscope); tissue mechanical tester; fluorescence photobleaching; alternating laser excitation fluorescence; fluorescence intensity distribution analysis; iverilog simulation analysis.
