Script for Waveforms->Protocol and filtering some characters

[kaamil1984]

Hi guys,

I'm spying communication between microcontroller and modem.

My Analog Discovery 2 with WaveForms does the job, but I want to filter out (or replace) some non-printable characters and continuously observe "transformed" version somewhere.

I have no idea how to get data from Spy tab.

Is it possible?

Hi @kaamil1984

Have you used the wait() function in your loop? like it is the above screenshot
The Script is executed in the main/GUI thread in order to be able to control this, so long loops without wait function will block the UI.

Hi @kaamil1984

You can use the "Save to File" in protocol tab and view/edit in external application
You can also use the Script tool:

I have tried something similar, but when I put ReceiveArray and Print in a while loop everything looks freezed.

So I came to the conclusion that script window (due to lack of async support?) is not able to print before script ends.

Is that true? Or maybe there is something that can wake up that window from inside loop?

I'm working with modem and communication is slow, sometimes there are few second pauses between request and response. I would like to see "live data" instead of post-mortem analysis :)

I didn't and I think this is it. 

One more question - is there some timer/delay that does not block main window?

Hi @kaamil1984

wait(1.2) # wait 1.2 seconds

Thank you sir!
