Recording 4 UART Signals at the same time.

[Sam_DAero]

Hi!

I have a need to record and compare four UART Rx signals simultaneously. 

I have been using the Logic mode to view them but ideally I want to see the received transmissions more clearly, and record them for review and comparison. 

In the protocol mode I can only seem to see one at a time. Is there a way to view all four? They all have the same serial port settings but come from different sources.

Thanks!

Hi @Sam_DAero

Currently the Protocol/UART/Spy supports two UART channels.
The next version will support 4 lines. I'm working on it.

@attilaAwesome thank you.

Out of interest, if I had two logic analysers, could I open two instances of waveforms and get all four?

Also - is there a way to cleanly record the traffic using the Logic mode instead?

Hi @Sam_DAero

You can have multiple Logic Analyzer interfaces open but a device has only one such resource, so only one interface can be active at a time.
The Logic Analyzer can record up to 256Mi samples and the Protocol 'unlimited'

Ah amazing! Works perfectly. Thanks for your help @attila
