HOWTO - LogicPort Trigger on Serial Character

07/17/2008 16:35

Synopsis: I was working on a serial multiplexor based on a Propeller development board. Because there could be many serial streams coming into or out of the mux, I needed to be able to analyze the serial stream in real-time to debug it and verify and validate it was working as I expected.

I bought a LogicPort 34 channel logic analyzer to help me do the job but figuring out the best way to get it to trigger on an incoming or outgoing serial character took me a little time to figure out. This is a quick tutorial on how I did it.
