Yes, the fix will be tested and released after the fix is confirmed. ETA the upcoming week, but it might change depending on complications with the testing

Also thank you for reporting the issue in the first place

Kind regards,
Andreas

Hi again,

Here's a PR for the bug fix https://github.com/NordicSemiconductor/pc-nrfconnect-ppk/pull/469

Looks like it might've been an endinaness issue after all. The fix should be added to the next PPK fw release

Kind regards,
Andreas

Hi again,

Could you share the PPK export (not CSV file but the PPK2 file)?

Kind regards,
Andreas

Thanks again :). I'll stick around 'till next week.

Cheers!!!

Hi again,

Partial answer here:

Regarding the X's it does not mean that the signal is floating at all. It simply means that the signal has changed 0 -> or 1->0 within the sampling period.

Regarding the order of the channels and the output, I've reached out internally to the developers to see if I they have some input to this. I've not gotten a reply yet, so it will most likely have to wait until early next week. Apologies for the inconvinence

Kind regards,
Andreas

If needed I can share here the ppk2 file I exported!!! :):):)

Edited!!!: Not share it here, instead share a link t download it.

[quote user="andyduarte0192"]And also, how to explain the behavior of the timestamp 36262ms (the second image I sent in my previous reply), even assuming the digital outputs are inverted in the csv file?[/quote]

Good point, I fixated too much on the first image, which were insufficient as evidence

I will look closer into this and see if I can find a better explanation. I'll check in here with a status tomorrow (Friday)

Kind regards,
Anderas

I also thought that MSB to the left and LSB to the right, but that's not what the header of the csv file says.

And also, how to explain the behavior of the timestamp 36262ms (the second image I sent in my previous reply), even assuming the digital outputs are inverted in the csv file?

Hi,

Thank you for expanding

[quote user="andyduarte0192"]With SDK I guess you mean what I show in this first image. [/quote]

Typically with SDK (Software development Kit), we refer to nRF Connect SDK and the version is corresponding to for instance v2.6.1. But no worries, I see that this part is not relevant for this question

[quote user="andyduarte0192"]

Sorry I didn't explain myself in a good way. These images show what I meant, "incorrectly" means that the digital outputs don't have the values I see in the graph in the software.

The digital outputs are organized as D0 D1 D2 D3 D4 D5 D6 D7.

In the following image below, at timestamp 30286ms, digital outputs should be 1,0,0,1,0,0,0,0, but the file shows different values, like if they were inverted.

[/quote]

Aha, this makes things more clear, and what you see is correct. Bit 0 is furthest to the right (often referred as least significant bit) and bit 7 is furthest to the left (most significant bit)

[quote user="andyduarte0192"]and those 'X' which I don't know what they mean.[/quote]

The X's mean that its not able to determine if it is 0 or 1 (if the voltage is somewhere in between, it could typically be anything). You don't want to assume that something that is 3.3V is logic high in a 5V device, when it is in theory closer to 5V than it is to 0V.

Kind regards,
Andreas

With SDK I guess you mean what I show in this first image.

In the following bellow, timestamp 36262ms, digital outputs should be 0,0,0,0,0,1,0,0, but the exported file shows different values

n the following bellow, timestamp 36291ms, digital outputs should be 00000100, although there's a falling edge at that exact timestamp, but the exported file shows different values, and those 'X' which I don't know what they mean.

Hi,

I see that this is your first case so I will give you some input as to what we would like to see w.r.t information in a general Devzone ticket.

For us to be able to help you it is important to get enough information about your issues/inquiry so that we can properly understand your issues. This is among

What SDK and version of SDK are you are using
What SoC's you are using
If you have any build or device logs showing the issue, then we recommend that you attach them to your description using insert -> code
If you don't have any logs, then images might also be helpful

In addition there are a couple of getting started resources I would recommend that you go through, among them are our NCS Fundamentals and Intermediate courses on https://academy.nordicsemi.com/. In the intermediate course there is also a course about debugging, which might be helpful for you to isolate the issue further before you raise an inquiry with a too general issue for us to be able to help.

Moving on to your issue:

[quote user=""]hen exporting the data collected, specifically the digital outputs, they are exporting incorrectly, but in the Data Logger tab they are presented correctly[/quote]

This is where an image or other attachment would be great to have. What do you mean with "incorrectly"? To us this could mean anything. Do you see the values in decimal in one place but in hex in the other place? Do you see different ascii values in the two places? Please expand upon this if possible

Kind regards,
Andreas
