Is it common in the captures for uart to have frame errors after applying the analyzers? I even used different wiring harness and got pretty much the same results.
Hey! Sorry for the incredible delay. This isn’t the first time that discourse has disabled all the alerts on me.
The best way to figure this out is to check if the UART capture and the protocol analyzer look like they line up when you look closely. This first example, we see framing errors because we’ve got the baud rate slightly off. Notice how the edges of the blue bit hexagons are a bit awkwardly placed and the hexagons seem to be a bit bigger than the toggling signal:
Next, look at this example, and see that the edges of the hexagons are lined up pretty closely with where the uart signal goes up and down:
You can adjust this by changing the baud rate of the uart analyzer settings. See if adjusting that gets you a better data capture.
