[001] Sigrok and Logic Analyzers 

I'm shocked to see this video only got 500 views! This is quality content! *Thumbs up*

The funny thing is that there really is no reason to use the original Saleae software with the clones because Sigrok is just so much more powerful with all of its protocol decoding. Thank you very much for your contribution to this amazing project!

I must say that this is the venerable mother load of USB logic analyzer videos. Moreover, it's a comprehensive and thorough treatise of available analyzers, limitations and compatible software. You certainly sold me on Sigrok open source software. Thank you for producing such a flawless video!

This is not just an awesome tutorial, but a really nice encouragement for getting into open-source development projects!

Given the vast quantity of well-meaning but extremely amateur RU-vid videos that leave one more confused than ever, THIS was a highly refreshing change. Clearly presented, well produced (post production etc) and extremely informative showing great insight and knowledge, especially for someone who claims to have only been involved in electronics for just six years (to the date of this video). I wish we had far more of such videos around, this is a great example of HOW to do it rather than the hundreds of, mostly failing, "how NOT to do it" ones. Awesome! (BTW I'm a graduate electronics engineer of over 43 years and a member of the IET for over 46! I learnt a LOT!!)

Just when I thought this couldn't get any better out comes the simulated circuit. This must have taken a great deal of effort to put together and present so well. Thank you Joel!

Finally! A great video that walks you through logic analyzers for us beginners. This is exactly what I was hoping to find. Cheers!

Wow! Superb video... Spend the whole hour without even having paused it! Thanks a million for taking the time to go through all the details. Much appreciated.

Great great stuff. Thanks for taking the time to do this!

Amazing video. It's great to have all those background information and your style of presentation is very clear. Thank you!

One of the best introductory videos about signal analysis I’ve come across. THANK YOU! It’s an eye-opener and shows what can be done with little effort. Standing on the shoulders of giants, of course, that already put lots of efforts into it. This video shows how to open ways, develop your knowledge and build the bridges between the big measuring instruments companies, the knowledge thieves and el-cheapo clone builders and a lively Open Source community making it all accessible and distribute knowledge by working together. Love it. Thanks to all!

Excellent video!!!!!! Thanks so much for taking the time to create this super useful content!

Very very good resume of the available low cost logic analyzer options!! I rely appreciate how you explained the weak probing that these devices provide when its coming to higher pulse rates, with the necessary higher sample rates, specially under a low number of channels on serial communication. When you look on the professional analyzers, probing is one of the most important, most complicated and even most expensive part on every high performance measurement system. But also when You are coming from the professional side you must also recognize that almost much more then 90% of the upcoming analyzing cases could be easily handled by these cheap devices. In a short, I don`t remember one only case where I was coming to the end by some equipment limitations, the major task was everything to get a "better view" whats where going on in the circuit or communication line. I also remember logic analyzers (more from the 90th) who where much less powerful, much less self explaining and very difficult to set up. They where much less flexible and very time consuming specially when it comes to the point where You have been forced to count out your capture count by count, bit by bit. So, after your nice explainings I will give it a $30 try with a Logic16, to see how it works and how the probing performance could be easily improved by a cheap and easy DIY solution. Thanks for Your lesson ;-)

Amazing video. So such information I have to re-watch many times. Thank you sir!

This is amazing! I am so glad I stumbled on this video. Thanks so much for the quality work here.

Watched the whole video in one go without skipping for even a single second! This happens the content has an extreme quality! Subbed..

What a beautiful presentation style, voice and content. Truly open source spirit. Thank you so much for sharing all this.

Goodness! What an eye opener having struggled with a DSO and never having heard of Sigrok or the cheap entry point logic analysers. Thank you so much for putting this together in such an interesting and detailed way! Subscribed! :-)

Wow, very well put together video. Impressed to say the least. Thanks for sharing your knowledge.

Thanks for your afford for this channel and the open source community. I really trying to help as well, it's only hard to find time, with a full time job and a family. So thanks again. Keep up the good work 👍🏻

Really great video, thank you for this. I will be re watching in a few weeks when my logic analyzer arrives.

OUTSTANDING.... Absolutely Outstanding Presentation and Content! After many decades of using Logic Analyzers to ply my craft and empirically learning most everything presented in this vid, I now have a ready reference for the Whys and Hows of it all. What a great job!

OMG! This is definitely high quality material! Thanks a lot!

Thank you for that wonderful introduction to sigrok. Signal decoding is something I have wanted to learn about and now I have a path towards doing that. Great work.

Great, excellent, amazing information from someone that is skilled with the required knowledge to present properly this materials. Thanks a lot!

This was my work for today. Watched the entire video, and tried things out on my own using my own Logic Analiser. Tried the CLI and learnt its advantages. Also forced my colleague to try this out. It is so inspiring to hear about your story with Sigrok. How you started and how it is now continued. This, I believe, is the most important take home message for me and it really is inspiring. I will switch speeds and re-watch this video from start to finish today itself! like I did another of yours yesterday. Fascinating amount of technical content mixed with your experience and philosophy in these videos. Thank you for your time spent creating this content. p.s. The length of videos are never long enough.

I was googling around seeing if I would need a logic analyzer later on down the road in my hobby. A lot of people said to just use the oscilloscope. After seeing this video, and that part about the decoder stacking: yep, I NEED one...

Thanks for producing this comprehensive video, very nice work ;)

I got as far as 5 mins into this and subscribed. I always go for open SW/HW wherever possible. Great video (judging on the first bit) and I'm looking forward to bringing on your other videos later.

Ive been involved in electronics all my life and Im now 67 but never in the software area and to see the work put into Sigrok is amazing, 99% of it goes clean over my head as much as I would love to understand the detail. Your work is truly impressive, I too would be incredibly proud if I had been able to do this level of development, stunning stuff thank you

Thank you for sharing your knowledge to us. Really appreciate!

Thank you for your work on PulseView. I use SIGROK and love the results!

This is one of the best quality videos I have seen on YT .

Thank you for the awesome job you've done on PulseView. it has really helped my project!

This was so incredibly useful, thank you! I was trying to figure out what logic analyzers are and which to get, and your video showed me that this is exactly what I need. Furthermore, the software blew me away! You've also helped me understand that one of those €30 analyzers is the much better choice.

this was really well done! thank you.

This is absolutely marvelous work! Thank you!!

Great video. what a perfect timing. I got one of those clone things just for simple projects but never saw how cool pulse view is.

Brilliantly presented and helpful video! Thanks for sharing.

Epic video. I'll probably need to re-watch in the future to recall everything contained in here.

One long video, well explained! Excellent!

Hi Quality information feeling myzelf back to be in college. Easy listening & calmly spoken. Good outline of pros & cons of different (logic/sampling) approaches. Furthermore, I like the sigrok (oh/os) itself. Well done !!!

This is a great video. Well done explains what is going on really well. Very consisce and well spoken. Kudos to you, I wish I had professors who taught/explain the way you do. Very well done..cheers mate!

I cannot thank you enough for this video on low cost logic analyzers and signal probing. I have a bunch of 8ch Saleae clone analyzers which I bought to help me debug a project that uses SPI digital to analog converters. They work with my Windows 7 laptop, but when I had to move to a new Windows 10 machine, I kept seeing only part of the recorded signals; now I understand why; there isn't enough bandwith in my new laptop's USB. Thank you for the tear down, showing the internal buffering in the 100MHz clone; I bought one on AliExpress once I saw your explanation; I hope it will work on the Win 10 machine. Thank you for making us see why a faster analyzer may be of no help at all, unless matched to better probing. Thank you for spending your time teaching us, complete strangers to you.

What a good video. Really professional production and very clear narration, you clearly know what you're doing. Just bought the Hobby Components analyzer and clips. Looking forward to playing with it and the GUI Sigrok software. I Liked and subscribed... thank you

Damn - three years for this to get my attention - Fantastic work !!!!!

Very informative! Thank you for making this video!

Thanks for the upload, tutorial, and your efforts working on this OSSW project. If anyone really needs to decode an IR device there is a project option available on the OSHW AVR Transistor Tester project for doing this. I know that was not the purpose of this demonstration but I figured it was worth plugging another OSHW project. The origin of the AVRTT project is available at mikrocontroller[dot] net/Articles/AVR_Transistortester -Jake

Nice video tutorial! I'm looking forward to tutorial about other devices supported by Sigrok!

Great video, and thanks for your coding contributions.

Really nice video! Couldn't stop watching!

wow, just wow. Such nice high-quality content. On the long side, but really taught me a lot so I guess lenght is not important. Thanks man, thanks

That’s a really bloody good video! I learned loads! Thanks so much!

Thank you for this video: this will probably open the gate to knowledge to many, including me.

new subscriber. All of your videos are great. thank you for your time doing these.

This video is so excellent. It could easily be cut into 3 excellent videos: An example of using sigrok-cli/pulseview, a comparison of open-source logic analyzers, & an explanation of the leads, clips, and what they do to a signal. That said, it's well worth the whole watch through... I saw this about 8 months ago, and re-visited to save myself some time explaining logic analyzers to a friend, but go figure I end up watching the whole video again.

Fantastic video - Thank-you.

Wow, great video! Thank you.

Very useful and informative video!

This tutorial is Gold.Bravo, thx for sharing

A great video and very interesting. Thanks.

After years of working Microcontrollers and circuit boards I am just now getting my first logic analyzer. What pushed me over the edge to get a new tool is the fact I have been having trouble writing to a old microcontroller and I need see what is being sent.. Wireshark wouldn't work on windows for the com port and I didn't want to hand decode them with o-scope. Great video!

Excellent video. Thanks.

high quality stuff dude! thanks

Thanks for the video, very informative and thorough.

GREAT JOB!!!

Sir! I think you're some kind of a Dr. Dolittle for digital circuitry! Supremely entertaining video. Thanks!

Fantastic video! Thank you very much

Excellent review! thanks

Wow, what an amazing video. Thx a lot.

This is by far of the best Logic Analyzer videos out there in RU-vid land bar none! I am not sure how Saelae charges $699 now for a logic analyze compared to what you can get get in a MSO Oscilloscope for half the price where you get a whole lot more test equipment capabilities.

Great video! 👏🏻👏🏻

Congratulations, good content

Really great and helpful video! Thanks a lot!

Thank you so much. Well done in so many ways.

Very interesting and helpful video, I have thinking of purchasing a logic analyzer and now I know which one to get and the fact that their is significant Open Source support is even more appealing. OpenTechLab great video, extremely helpful and enlightening. I think the Saleae 16 100MHZ is the correct one for me. Ps: I commend you on the scope of the project you took upon yourself to implement.

Great content. Thanks for the effort. Subscribed!

My mind is blown so many times in this single video..

incredible ! thank you so much for this video :)

Thank you! Great video!

awesome video! Liked a lot!!!!

Fantastic explanations !

Do appreciate the wiseness to tape everything down... I had a setup where I had to move everything to get readings, so I taped everything down to a paddle for table-tennis.^^

Great video, thanks.

This is a brilliant explanation and review very well done sir

wonderful tutorial.

Excellent, excellent voice and good info

Thank You for your work on this, a most excellent presentation, a joy to watch! I did not realize how useful these cheapo devices have become. The Sigrok software seems great. I would recommend the old writings of Jim Williams and Robert Pease on probing. I have Bobs book on troubleshooting which I highly recommend. The older LT application books also have a lot of good stuff in them. I try to use open source as much as possible, but it is not always feasible. I believe open source is the way to go both for amateurs and industry. Also in later years in EU we had (unfortunately) to use itar free components and software for space and defence related projects in order to stay competitive.

Thanks for the video, it is really good! I have one of the cheap FX2LP boards, quite interesting piece of hardware for the price!

This is a great video on these devices for us non engineers. I have the open bench one and never really got much use out of it and thought it was crap and put it in the junk bin. But I really have a need to spy on some spi comms etc and was going to get a salae. Maybe I'll try sigrok and the old open bench again. Thanks for the video!!!

Sehr gute Übersicht und sehr gut Erklärt...

thanks for the video .......... great content

Thankyou for the video. Instant subscription.

Thank you very much...Excellent video

This was the tutorial i came across thank you alot.

Man alive! I must thank you very very very very much for your efforts.... I just stumbled across this video purely by chance / RU-vid algorithm, I'd been looking for ages for a piece of software that does just what sigrok & pulseview is capable of. I'd ignored the existence of pulseview for as long as I can remember due to being under the impression that it was related to pulseaudio; that type of pointless audio interference on FreeBSD is something I detest with impunity. Cloned hardware is a bitch, but it does allow for some penniless genius with very limited resources access to something that would otherwise be impossible.

Thank you for your great video and sigrok, I almost throw away my Sump logic analyzer because couldn't find software for it until saw this video

Best video ever on this topic! sadly people are more into cats and stuff and you did not get the enough attention you deserve! but keep it up, dude!

hell yeah awesome. this video is totally underrated

wow, impressive. You are a great communicator.
