This is a sloppy logic analyzer using GPIOs. It comes with a script to isolate a CPU for polling. While this is definitely not a production level analyzer, it can be a helpful first view when remote debugging. Read the documentation for details.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
