Open Source Logic Analyzers? · Slashdot Mirror

Posted by Cliff on Monday April 12, 2004 @06:35AM from the testing-and-comparing-digital-signals dept.

Rorschach1 asks: "I'm a hardware hacker, doing my part to develop useful open source projects, but my projects are getting more ambitious and my test equipment just isn't keeping up. PC based oscilloscopes have been discussed here before, but I'm particularly in need of a logic analyzer. The BitScope does offer an 8-channel analyzer with Linux support, but that hardly compares to most commercial offerings. I'm also concerned by the fact that I can't find any independent reviews of the device, and I'm hesitant to shell out $500 without knowing what I'm getting into. A logic analyzer is a pretty simple device. My current setup runs on a dedicated 486 with ancient DOS-based software. Surely there must be a more modern option available that'll work under Linux, but so far I've been able to find nothing. Perhaps someone can point me in the right direction?"

Nothing terribly fancy. Say 16 channels and 50mhz. Much of what I'm doing is SPI bus and only needs a few channels, but I do sometimes find myself needing more than the 8 provided by the BitScope.

Something that could look at a data line and clock line and give me a hex dump of the data would be nice, but I don't really need any more intelligence than that.
