gtk-wave IS an excellent GUI for viewing and analyzing digital wave forms. At least use its codebase. Why reinvent the wheel? I wrote a simple command line app for triggering and converting the data from the serial port to vcd data for gtk-wave. I wrote nothing noteworthy, as I wound up not needing compression for my application, but I may need it in the future for an upcoming project.

Did you complete this project? If so, what GUI did you use for your analyzer? I’ve started writing a (generic) GUI for the Saleae Logic analyzer which I’d like to spread and get more users of. It’s still very nice, but should be quite portable between platforms and analyzer.

Hi Peter,
Thank you for your encouragement. Aside from studying (the relatively simple) vcd file format, I currently (only) have a couple of tables and finite state machines for implementing these ideas. Unfortunately mid August to mid September is hell at work. When things cut back a bit and I have more time, I’ll post my code. When things let up, I’ll be happy to share some more of this project.

I do expect the recording of changes only to save many kB of precious RAM.

Hi,

your LA looks very promising. There are really very smart ideas implemented. I would like to take a look at the source code and eventually contribute back. Can you provide a link to the source code?

Regards,
Peter
