How to expert large SPI transfers?

Postby drzwave » Fri Feb 02, 2018 7:22 pm

Is there a way in Picoscope 6.12.9 to output more than the first few hundred bytes of an SPI transfer?

I have several multi-K byte SPI transfers and I need to be able to compare the good ones from the bad.
But P6 displays the entire multi-K transfer as a single line in the hex table. When I export the file, I get:

Packet,Start Time,End Time,Data,
1,-0.558881873890542,1.00000024929687,1 FD E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 01 FF FF E4 ...,

Note the ... at the end - this is no where NEAR the end of the data. This is just the beginning!
I need all the other data. Is there a way to get it to all come out?
This is one single huge SPI transfer. No de-assertion of chip select during these transfers.
I can't easily chop up the transfers using the cursors as the transfers are so big.


One other feature I'd really like in the SPI decoder is to put BOTH the MISO and MOSI into a single decoder especially when exporting.

Can you post a psdata file so that we can take a look with your data.

Combining decodes is on the feature request list, not just for MISO and MOSI, but for decodes in general where sequence matters.
