Low cost logic analyzer
Ғылым және технология
In this video I will show how powerful these cheap 8-channel logic analyzers are.
We will use Sigrok pulseview and the built-in protocol functions to analyze UART and even USB signals.

Thanks for doing this video. I bought one of these many, many years ago as a backup in case my Saleae (the original, which this clones) ever died, but kind of assumed that it was difficult to get working properly, so I never bothered powering it up. If I ever find it, I'm now motivated to give it a try, even though my genuine unit is still working.

Haha totally recognize this, I bought this clone 6 months ago and could not get it working and gave up (and built the poor mans logic analyzer from the previous video) Then I decided to make a video, forcing myself to dig a bit deeper. The main issue was for me was that you need to wait for the driver installation "Zadig" it takes like...a minute or so! Pleas check the links I included, some minor points explained there which may help.
Thank you for making this fantastic video. I got my logic analyser working as a result of following your instructions. This now will allow me to diagnose the data on my NMEA 2000 network.

Great to hear that, just looked it up, NMEA 2000 is a bit similar to CAN as used in cars? I make these videos just for fun, and I actually learn a lot from the comments :-)
Excelente vídeo!! Parabéns e muito obrigado!!
Very Clear and well put together, Thank You for the video, very educational.👌

Thanks man!
I bought one of these years back and never used when studying electronics, amateur radio and RF engineering. Wound up picking up a HP 6601A logic analyzer with 16533 scope plugin card from the UofM Property Disposition store pre plandemic and played around with that to make sure was functioning. Decided would wait to use again once I could backup the HD and ideally install a converter to use a modern SSD drive, instead of the SCSI older drive. I had no idea there was the decoding function with the Saleae clone. That is really handy and I guess the only thing that comes to mind that would be even better, would be some sort of iteration algorithm to automate the communication and protocol for an easier reverse engineering tool. Kind of like a Universal Radio Hacker app I guess comes to mind, so open source communication protocol analyzer. Anyways, great video and subscribed. Thanks for sharing the Elements use as well, downloaded a copy and will have to try to use sometime when I get around to if I can get rid of those Stalin's Daughter whatever they are malicious on that side of the lake and beyond seems invasive youth that are just dumb in research stations I'm guessing or they claim. Thanks again and looking forward to more videos.

Thank you jafinch78! Yes it would be great if SigRok could recognize the protocol, similar to those cheap "universal component testers" just put in a part, press the button and you get the result
what does the clk line do?
It's possible to use RPiPico as >10Mhz >16x logic analyzer with Sigrok which is also cheap, can you make a video about it?
Nice. I liked too much the name of your channel.

I much prefer the (comparably low cost) Openbench Logic Analyzer (OLS) with its 200MSamples-per-second capture; unfortunately it doesn't seem to be sold anymore...

Never heard of the Openbench Logic Analyzer (OLS) , the clone product from the video is ok, but limited to 24MHz.

@@smartpowerelectronics8779 That's not really surprising, for some reason it never became well known, in spite of it being capable of 200MSPS on 16bits, for only $50. It was a board built with an on-board RAM buffer in an FPGA, built by Dangerous Prototypes and sold at the time by well-known outlets like Seeed Studio and Sparkfun. Sigrok has of course support for it, but it also has its own jawa-based cross-platform client. It had a multi-level cascading conditional trigger and because it implemented run length encoding on the captured data, its relatively small buffer could be stretched to cover relatively huge time spans even at maximum sampling speed, as long as the actual signal measured included large pauses where the lines didn't change. It's a shame it isn't sold anymore...
