low cost usb logic analyzer?

[biff44]

Anyone have a low cost logic analyzer that they consider "good". want at least 16 channels and 24 MHz. saw one on ebay, Saleae, but only 8 channels.

Want something that comes with the wires/clip leads, and some decent desktop software to see signals.

Any suggestions? Thanks

I have never used them but the cheapest would probably be something like https://www.seeedstudio.com/depot/open-workbench-logic-sniffer-p-612.html?cPath=63_69

I have one - works nice - not pro but nice and really cheap for the price

I just open some page with one 32ch pro device, when I saw the price, reflexively I closed the page.

I made my own, 2 weeks ago. USB bus powered, 8 channels, 12 MHz sampling, with uC running on "only" 24 MHz. There is possibility to extend it to 16 channels and increase the sampling rate by overclocking uC.

It would be worthwhile uploading the data here so EDAboard users can view it!

Logic signal is from PCM2707 3.3V USB to I2S audio bridge. By default word select frequency is 48 kHz (P1.2), and clock is 64 * 48 kHz = 3.072 MHz (P1.1).

Saleae make 16 channel ones and they are VERY good. https://www.saleae.com/
