@steven.dutemple This is great feedback for the team here! Thanks so much for sharing these.
The v1 software had everything in the same file, which is easy to decode and process… Out of curiosity, why was this changed?
This feature is actually available now in the latest version of the software:
Logic 2 Download link → Saleae - Changelog
I just wrote up a user guide entry for it below under “Exporting the Data Table”:
Is that the feature you needed?
Tim, Thanks for taking the time to respond. Actually, I was referring to having all binary data for all channels in the same file (similar to what you do in the V1 software, where you provide a timestamp for the sample along with a byte - or word for 16-bit devices - providing samples for all channels). Providing a sample point on the change of any data (but providing all the data) makes synchronizing the samples easier. I’m currently experiencing an issue where the visual display does not sync up with the sample data - the data file tells me the signal transition is at 16.824966536, but the GUI indicates the same transition is a 16.824921144). This makes it harder to find a transition visually if you know the time… (I’m going to create another issue describing this problem).
- Why was the option to only save samples when data changes removed from the CSV options? This was very handy and helped reduce the size of the CSV files exported.
In Logic 2, we actually removed the option to save all samples for digital channels. By default, the samples should only be saved when data changes. Can you confirm this is the case for you?
Yes, and this is fine. The only thing I’d like to see is an option to be able to put all data in the same file (see my comment above). I agree there’s a significant decrease in file size for individual channels, but writing software to “align” multiple files is a challenge. Having a data point written to file when any channel changes (and providing all the data channels in the sample) would result in a large file, but it would be a single file, and much easier to process…
- When exporting the data, why not name the files according to the user’s assignments (For example, if I change the name of the channels in the GUI, why are the filenames still Digital_1, Digital_2, etc…?)
This is a great idea. I’d like to get this up on our ideas page so we can track user interest in this before committing it to the roadmap. Feel free to post that idea there! I think this is a fantastic idea. Sorry we didn’t implement it this way to begin with.

I will add this request (officially)… 
Got other ideas as well … you’ll be seeing them shortly…
- It really would be nice if v2 software could import v1 logictraces… We have a lot of validation data that has been captured using Saleae devices, and have to keep both versions of the software available just so we can continue consulting them… Really?
You’re absolutely right. Sorry for the hassle this causes. Several other users reported their need for this feature as well. Right now, we’re tracking this via the idea post below. It’s garnered a lot of attention so far. I’ll add your comment there to keep track of your need for this as well.
