Introduction

The alternative OLS-client provides a software client for the Open Bench Logic Sniffer logic analyser hardware.

The Open Bench Logic Sniffer is the result of a collaboration between Gadget Factory and Dangerous Prototypes. They created a cheap custom implementation of the SUMP client (developed by Michael Poppitz), and released it as Open Source project.
The original SUMP project already contained a workable client of its own. While this client was feature complete and working quite well, it was no longer actively developed and maintained. Being a developer and loving Open Source, I immediately started hacking and tweaking it. The result? An alternative SUMP client.

What other people say about...

I had to rock some intense LAing today, and I just wanted to say that the latest version is fantastic! I've completely abandoned the old version for yours, and moved it to the top of the wiki software list :) It's a joy to use and it doesn't feel like Java. In my opinion this is nicer and richer than the Saleae client (I use the Saleae a lot too).
Great work! Thank you so much! — Ian (Dangerous Prototypes)

It keeps getting better and better! I've officially started using your client exclusively, I just spent the last couple days troubleshooting some SPI output from the AVR8 Soft Processor core project and your client didn't miss a beat — Jack Gasset (Gadget Factory)

Features

The alternative Java client provides the following features:

• Cross platform: the client runs on Mac OSX (32/64-bit), Windows (32/64 bit), Linux (32/64 bit) and Solaris (32 bit);
• Simple installation: no longer fiddling with the serial libraries (RXTX) in order to get the client up and running. The client embeds the suitable serial libraries for several operating systems;
• Pluggable: adding new functionality on the fly is possible and as easy as copying files to a single directory;
• Look good, and feel good: the client has a good look and feel, aiming at being as usable as possible and adhering to the human interface guidelines of the platform it is running on.
