This announces the Open Instrumentation Project (OIP), which has been formed
to support open-source software and low cost hardware for electronic
instrumentation.
The objective is to make electronic instrumentation readily accessible to
students, hobbiests, engineers and scientists. This then allows independent
circuit development and project-based learning in electronics.
Three instruments have been completed:
- dual channel, 20MSample/sec oscilloscope
- 100kHz waveform generator
- low-frequency vector-network analyser
Screen shots and the software for these instruments are available from
sourceforge at:
http://sourceforge.net/projects/oip/
The software is licensed under the GPL.
Low-cost hardware using this software is available from Syscomp Electronic
Design:
http://www.syscompdesign.com/
The software uses the Tcl/Tk language without extensions, which makes it
simple to install and maintain. The current cross-platform implementation
runs under Windows and Linux operating systems. We are currently testing the
Mac OS-X version.
Tcl/Tk is a scripting language that is interpreted text. It is simple for
non-experts to add features to the graphical user interface.
The hardware uses the USB interface with drivers and hardware that emulate a
high-speed serial port, which simplifies programming. No USB programming is
required. The Windows and Mac drivers are available from FTDI at
http://www.ftdichip.com/
Linux drivers are available in the Linux kernel from version 2.4 onward.
Invitation
----------
The current releases of software provide basic features for the instruments,
but there are many that could be added. For example, the oscilloscope would
benefit from 'waveform math' commands. The waveform generator could be
configured as an audio sweep generator. Contributions are welcome and will
be shared with the user community.
