Raspberry Pi Pico as a 24-Channel Logic Analyzer

[@SomeGuyStudio-r6y]

My man you straight up saved my ass, spent hours trying to figure out why my other pico's SPI ports werent giving good data. This was a god sent

[@anissoulhaci2653]

Appreciate that thanks !

[@wizardman1313]

WOW! Its sheer coincidence that I clicked on this video that turned out to be very relevant to me. I had trouble with my own addressable led project, so I was checking out oscilloscopes to buy. Didn't consider logic analyzers but out of curiosity, I checked out this video. I love the fact that you demoed the exact use case that I wanted to know that this would work for. Potentially saved me some money! Liked and Subscribed!

Glad it was helpful!

i was searching logic analyzer for pico thanks to put this video on youtube

Appreciate it mate !

Looks like it will decode Z80 signals too, nice

Thanks for sharing the info. What is the maximum measuring speed?

[@anissoulhaci2653]

there is a png image inside of the directory "PICO_Sigrok_Rates.PNG" that shows each data channel input max sample rate with its limitations

[@kohliabhi]

Not sure if I missed it, but any idea what is the max capture rate / freq using pico ?

Meraviglioso

When I want to scan devices connected to COM4 (I have a Raspberry Pi Pico connected there), I press the scan button, but it doesn't detect the device. I've tried changing USB ports and cables, but it's still not working.

[@anissoulhaci2653]

yes , its a bit tricky out there , just make sure that there is no software that makes the COM ports busy , if it doesn't work try to reboot your PC

[@yasirrakhurrafat1142]

Ayo bro, would this be able to log a lot of data that is at a very high sample rate, for a long period of time also?

great work! How to use the 3 analog IOs as digital to get true 24 digital channels?

Looks interesting. But could you give some information on the Sigrok parts to install and also how to connect the pico to the board under test (which pin is which channel)?

[@anissoulhaci2653]

@@aamiddel8646 i mentioned everything on the video , and the pins, there is a png file representing each gpio pin with their channel

[@aamiddel8646]

@@anissoulhaci2653 Thanks for the response. But you might consider to show it rather then mentioning. I have not seen the png file. Would have been nicer if you showed in the video.

Very good and useful project !

Glad you think so!

does this work for pico W too?

The baudrate doesn't matter because sigrok-pico using CDC serial.

[@Doctor_MB]

Interesting. The only way I could get Pulseview to see the Pico was when I did not set the BAUD rate during configuration, and maybe that is why. I should look into this further, but I am finding my $12 HiLetgo device with max 24MHz sample rate is now working pretty well, though getting the PICO working was fun.
