I can no longer support the following project because the CPLDs are very hard to get and I no longer have access to the programmer. Also, the schematic and PCB program I used (WinDraft) is no longer available. Let me know if you would like the CPLD and/or the VB source files.

Single Board Logic Analyzer - October 2004 Circuit Cellar

Updated 21 May 2005 with version 1.4 of DSO_LA and help files. It contains improvements, described in the help file, and an updated Read_me file specifically for the SBLA. I am leaving the original files here just in case anyone requires them.

Here are some pictures from one of the users of the SBLA.

Updated 9 Oct 2004

This is my Single Board Logic Analyzer as published in the October 2004 issue of Circuit Cellar magazine. Its design is based on the DSO/LA which is described below. After designing and building the DSO/LA I wanted to see how difficult it would be to design a single board Logic Analyzer. This project and article is the result. All the information required for building the SBLA is contained in the file. The sample screen shots from the DSO/LA, minus the analog portion, show the presentation of the SBLA. If there is enough interest I will obtain printed circuit boards and purchase all the components necessary for kits which I will make available for cost plus.

The file _ReadMe.txt contains a list of changes, a list of the files in the zip, as well as some construction information.

For anyone who is interested here is the latest version of the Altera files for the CPLD.

Please realize that I no longer have a valid version of the Altera software so I will not be able to help you if you have questions on how to use it.
