LogicAnalyzer: a Raspberry Pi Pico-based 24 channel logic analyzer

Agustín Gimenez Bernad leads development of LogicAnalyzer, an inexpensive 24 channel logic analyzer with 100Msps, 32k samples deep, edge triggers and pattern triggers.

LogicAnalyzer is a very cheap analyzer based on a Raspberry Pico (or Pico W). The analyzer offers up to 24 digital channels, pre and post trigger sampling, edge trigger and pattern trigger up to 16 bits.

Additionally to the hardware the logic analyzer also includes a powerful software (Windows only for now) where you can visualize the captured data, export captures, use protocol analyzers, etc.

The latest version (5.0) adds Burst mode. With burst mode you can capture blocks of data and the analyzer will rearm itself immediately and capture more data when the trigger condition is met again.

Check out the details, code, and boards in the GitHub repo here.
