Virtual Logic Analyser

©Tim Jackson, Sept.2003

Low cost, industrial speed logic analyser. Independent of manufacturer, needs no special hardware.		Wireless Data logging without interrupting machine operation.

Control system developers: See your software run, check timings and sequences before connecting outputs.		Service engineers: Capture a machine's running sequence up to the point of failure, in the field.

The Virtual Logic Analyser records a logic analyser trace set from live or recorded video.

Programmable Logic Controllers and other instruments display information through LEDs on the front panel. This provides a mass of information but it is difficult to observe rapid changes in the display, or to monitor it over a long period of time.

The Virtual Logic Analyser allows you to examine LED timing in detail and store the data in a very compact form.

This software is under development. A beta test version is now available for free download.
Registered beta testers will receive a free copy of the first commercial release of the Virtual Logic Analyser.

System requirements

Microsoft Windows™ 98 (or higher) operating system.
For live capture, a Windows-compatible video camera - either a "webcam" or camcorder with a video capture card. Computer hardware compatible with the chosen camera system. Some (older, cheaper) webcams are not sensitive enough to reliably record some panel LEDs.
A minimum of 64MB RAM is recommended for use with video files.
A graphics display of at least 600x800 pixels resolution
