More than one Protocol window?

[Wayne.B]

The protocol options and features in WaveForms are great and do just what I need. The only issue it looks like Waveforms only supports one Protocol window, hence 1 UART.
I need to monitor serial communications between two devices, which means I need two RX inputs. 

Is there a way to achieve this with the latest version?

Hi @Wayne.B

I wanted to say not, but I just notice that such option is already added
Use the UART Spy in the beta version: https://forum.digilentinc.com/topic/8908-waveforms-beta-download/

Oh nice! Yes, I tried it out and it works. Thank you.

FYI: To get it to work reliably at 921.6K I had to drop the Spy Rate to 2X. It looks correct but I am getting "Samples Lost" warnings.

My two devices have different line terminators one is CR and the other CR LF. I can only make one global choice, so its a little weird. I'll live with it though, this really helps.

Hi @Wayne.B

In case you are using Analog Discovery, the "Samples Lost" indicates device buffer overflow, loosing data while streaming to computer.
Try using the 4th device configuration which allocates 16k samples for digital input (Logic Analyzer).
