Software
The oscilloscope, generator, and digital I/O are operated from a software GUI (graphic user interface) included with the hardware. The software is open-source and source code is included. The software is written in Tcl/Tk, a scripting language that is easy to learn yet powerful for creating GUIs. It runs under Windows, Linux, Unix, and Mac operating systems.
CircuitGear is compatible with National Instruments LabVIEW, MATLAB, Visual Basic, and any application or programming language which can access serial ports. Syscomp provides LabVIEW example VIs that demonstrate how to control CircuitGear. Screen shots of the LabVIEW examples are shown below. The LabVIEW examples are available on the download page.
