8 channel logic Analyzer for 5 bucks

[Larz60+]

I don't like to show items that you have to pay for, but if you're writing embedded code and need to analyze or synchronize some signals, the cost of this item is extermely low. I recall paying over 10K for a logic analyzer back in the 1980's which was about right for a good one at the time.

Here you have 8 Channels, with 256k recording size @ 20MHz and a lot more for a whopping $4.90 US.

If you need one, a mighty good price: https://www.seeedstudio.com/Logic-Pirate-p-1750.html

What can you do concretely with this?

What can you do concretely with this?

it could be used on code where you want to syncronize timer and a/d converter in a circuit. This would require only 2 channels, but modern logic analyzers in general are sold in increments of 8 channels start at hundreds of dollars. I expect that this will change soon.

In the past (1980's), I used them quite often, for example to syncronize stepper motor movement (when motor ramping was done by software) to show time between steps. Or to trace interrupt timing on several inputs, happening at close intervals, to see the order and timing of the interrupts.

Here's an example (even though code is not python) that would use all 8 channels:
