I started analyzing ECLab.exe, here are my first results about galvani

[JhonFlash3008]

@fg-personal galvani has been updated and should work fine now with EC-Lab v11.50

It looks like the bytes between the labels do not hold type information. They seem to be:

1. length of the unit string in bytes
2. unit string (e.g. V or mA)
3. one null byte
4. length of the label string
5. label string (e.g. time/s or control/V/mA)
6. 0..3 null bytes

At least I can now read all column labels and units. I think I will look further into this and try and find the type information.

Thanks @ilka-schulz , this looks very helpful. I will look at it in more detail next week when I have some vacation.

There is also an experimental way to find out all columns:

I think we could try to synthesize our own MPR files and add columns with different colIDs. For each colID, we could try different column widths (2, 4 or 8 bytes). We could then try to convert these MPR files to MPT files using the EC-Lab GUI.

@chatcannon If you could write the code to synthesize MPR files, I would manually do the work of converting them with EC-Lab. Judging from the strings found in the EClab.exe, there are around 250 different column IDs (some IDs are not used in the production EC-Lab software).

Anyways, I will probably start to work my way into disassembling. That might be the cleaner way and maybe that skill will be useful in the future ;)

I have been playing around with radare2 and ghidra but I was not able to retrieve the type information of those columns. I will now try to synthesize MPR files and let EC-Lab convert them to MPT files. I bet I can automate the process and let my program handle the EC-Lab GUI.

Anyways, I will be on holiday at the end of the year, so do not expect results for another month.

@ilka-schulz, did you see any change in EC-Lab 11.50? The galvani code isn't working for newer versions, but hopefully some small fixes in the "MPTfileCSV" function might be a temporary solution.

If you didn't, sorry for the dumb question, but which software did you use to check the exe file? (just to be sure I am not missing anything, I wasn't able to find this info with objdump)

I followed up the discussion in the other issue, looking forward for the new release (the one after 0.3.0) including the changes
