This is logic analyzer project i started a while ago. It can use a xmos dev board to capture signals.
Main feature of the GUI is that its easy to use. You can simply drag the waveform around or drag the view window in the minimap below. Zoom is done using the mouse wheel. Channels can be assigned custom names or colors and also other colors are selectable. To communicate with the board it uses the XTAG programming interface and can automatically find the correct port.
The software is for now pretty crude and needs the basic functions to be finished, but in the future more advanced stuff is planned for it like communication decoding and terminals.
PC side software now available for download.The archive contains the VB.net 2008 source code and the compiled exe along with a example waveform savefile so you can open it and have a look (test.xwf)
If you find a bug just say it and il try to fix it.
