Re: Why does CAN J1939 decoding require connected scope ?

although perhaps I'm missing an important point which is that .psdata by it's nature is just about raw data and the display of CAN/J1939 or any other protocol is about processing on the host ?

Re: Why does CAN J1939 decoding require connected scope ?

I had an informative email exchange with Picoscope and learned the following: -Only T&M 4000 series scopes get J1939 decoder because the programming of it is specific to same 4000 series from Automotive. -You can run Automotive software in demo mode (without a connected scope) to decode J1939 from ....

Re: CAN-FD long capture

If I have a lot of time (2 weeks or so) I will reverse engineer the .psdata format and save in .psdata (because the picoscope UI is better than sigrok pulseview) Benno Benno, tried PMing you, but the message sits in outbox for whatever reason. Noticed that latest beta ( Windows only ) includes a .p...

Re: timestap of trigger

Hi Benno. I was not using this functionality in Picoscope 6 if my 4444 even supported it. As I look for this feature in Picoscope 7 because of your inquiry I wonder about hardware support for timestamp. Are you asking with regards to your 4444 because I did not think that 4444 has hardware support f...

Re: Why does CAN J1939 decoding require connected scope ?

Thanks for replying Willem43. Yes, I do remember seeing that J1939 only works for certain series of scopes. I'd thought this was due to capability of scopes (i.e. buffer memory ), but as I remember some larger buffer versions of 3000 series perhaps this isn't the case. All processing of data is happ...

Re: Why does CAN J1939 decoding require connected scope ?

I should be able to decode J1939 without scope attached ?

Why does CAN J1939 decoding require connected scope ?

Hi Forum. If my scope (4444) is attached when I open a particular .psdata with decoded J1939 then I see decoded data and see "CAN J1939" among the list of available decoders. If I open the .psdata in demo mode without 4444 attached then I don't see J1939. Is there some processing of J1939 data that ...

Crash log sends work ?

Hi Pico. I just crashed Picoscope latest beta on Linux when deleting a mask. A prompt appeared asking if I wanted to send something ( assume crash log, but didn't see mention on dialog ). Does this mechanism work or do I need to explicitly send ?

Re: What can be determined by looking at serial waveform ?

like so many times before attachments seem problematic on this forum. I tried uploading a 4.8MB psdata of relevant serial waveform, but receive a message about "HTTP Error"

What can be determined by looking at serial waveform ?

Hi Forum. I was evaluating a communication protocol on a bus trying to isolate some attenuation at the assorted locations of bus when I realized how poor my skills at interpreting a waveform when I don't know the protocol. The only thing I could determine about this waveform is ~9.5VDC between cente...

Re: Memory and USB speed confusion

I'm trying to understand what motivation non-Picoscope brands have to write .psdata files ? I suppose a non-Picoscope brand being able to read .psdata might increase the possibility of migration to other brands, but it doesn't seem like a reason for concern at least for T&M which doesn't provide any...
