Re: Accessing metadata from .psdata files

Depends of how good you are in hacking but the XML where all the info of the traces is in is in the .psdata file But you need a lot of programming experience to find it and connect the dots. You need to find out for yourself I will not help you with this, because the format is proprietary of picotec...

Re: Options for decoding I3C?

What is te max baud rade of the I3C bus you want to scan.

Re: Accessing metadata from .psdata files

The file format is closed proprietary. So no possibility of reading the metadata from the .psdata XML.

Why don't you use the date and time of the .psdata files.

Re: Max number of Picoscope 4444 usable on a computer

then your only option is to have 2 versions of Picoscope running at the same time 1 for each scope.
the problem is to get them in sync with triggers.

Re: Automatically saves waveforms when triggered

you can do this with alarms.
be aware you can fill your harddisk in a short amount of time if you have a lot of triggers.

Re: Max number of Picoscope 4444 usable on a computer

2 of the 4444 scopes at the same time is no problem.

But remember you don't get 8 channels in picoscope !
You get 2 times the picoscope window open with 4 channels on each screen !
The total number of channels will be 8 but not in program.

Unless you write your own software in the SDK.

Re: Y Axis Rescaling on AC coupled Display

As far as I know you have only a 250mV offset in the mv ranges. But there are 2 solutions to your problem. They are only working if the GND of your 5V trouble circuit is not connected to the GND of your PC. Most simple is have a external 5V supply that is stable connect the GND of the 5V supply and ...

Re: Memory and USB speed confusion

I also love to have the option to write .psdata files from the SDK if there is a scope connected at the moment of writing the file. But if you know how the file is formatted then you know there is a little more in the .psdata file than only the scanned data values of the scope. There is a XML file i...

So you can process the data in the file. https://stackoverflow.com/questions/874461/read-mat-files-in-python P.S. the counting of frequency should be done in python on the data read from the mat file. so the number of rising / faling edges over the sample timest...

Re: Memory and USB speed confusion

What you pay for a picoscope is for a big part also for software development.
If you compare the quality and possibilities of the software and the format is open the cheap competition can sell cheap products with quality software bundled.

Re: Memory and USB speed confusion

I have done this a long time ago, I can read .psdata files but not write them. Probably because there are some CRC's that check the validity of the data. This was back in 2012 and have no time to document it or investigate where the CRC's are. My start point in 2012 was ZipLib.dll. I had no urgent n...

Re: Memory and USB speed confusion

I also prefer picoscope, because of the UI and the possibility of using the SDK.
The only downside is if you use the SDK then there is no way to view the results in picoscope software.
Unless you reverse engineer the .psdata format 8)

You know the 2000 series is USB-2 scope and you wont get the USB-3 speeds.
