How and Why to Use a Logic Analyzer

[@nsummy]

Thank you. This should have more views. I wanted a quick and dirty explanation of what they do without watching a 20 minute video!

Thanks! Really glad you enjoyed!

The best explanation on KZbin. I subscribed.

Great video dude! I'm so getting one now, sadly I don't live in the US and can't quite use your link. Thanks!

Thanks! Glad you liked it!

As a software engineer trying to get into hardware, this absolutely blew my mind. Great video. I had never asked myself if you could convert digital signals from say, a USB port. Whenever you showed that working in the video it seemed so obvious. My question is, does that mean it’s possible to transport data reliably over electricity? Is that how those powerline internet adapters work?

Really glad you enjoyed! I have no idea - I didn't even think that was a possibility. Interesting thought!

I agree, great down and dirty view, which is what I was looking for. When would you use an oscilloscope in this process? To help you find the Transmit and Receive pins? Or do you even need an oscilloscope to help find and capture data and it can all be done with a logic analyzer?

[@PageKey]

Great questions! I hesitate to answer since I'm not an electrical engineer and this is getting a bit out of my wheelhouse. My impression is that oscilloscopes are for analog signals, so you can view the waveform. They also seem to be more expensive than logic analyzers, and I think many of them have built-in functions for handling digital signals, too. I also discovered through trial and error that many signals, such as those transmitted by USB, are way too fast to be captured by the cheap logic analyzer used in this video. That being said, this logic analyzer should be able to capture things like serial, I2C, SPI, and more. I hope this answers your question, or at least helps a bit!

Nice! Thank you!

best 3 minutes than a 20 min

short and sweer, thanks

Looolllllll I love this video.

I bought mine from China but there is no software included. Is there a link for a generic software for this?

[@PageKey]

You should be able to download the software here: www.saleae.com/downloads/ It's what was used in the video - hopefully it's also compatible with the analyzer you bought!

[@englenamhtamyt]

@@PageKey Thanks. It worked for me now. I just needed to install the drivers so the device can be properly recognized by my PC.

PAGEKEY TECH, which USB logic analyzers are cheap and have more than 16 or 32 logic analyzer channels?

[@PageKey]

No idea! Amazon may have something

[@dwudcuqoyl1465]

very usefull device to test out some of the clones of devices from amazon( ya know the ones that come with no datasheet and the chips have no readable serial on them yea those ones( got a signal gen that needed some heavy reprograming as it was outputing its OWN boot message as the clock signal 😂 but hey it was $10 )

[@PageKey]

Sounds like you're a legendary debugger if you were able to figure that out 😂

[@dwudcuqoyl1465]

@@PageKey its part of the fun but I like these ad chips cause they make excellent mclks for larger synths( i.e 6ghz signal sources for radar applications). Excelent video though very usefull( also buspirate helps alot )
