  1. @attilaDoes this result in a data file I can parse for picking out just the decoded values?

    The analog display is a nice touch, but does nothing for me in this particular instance.  I just need the SPI data in a file, or a way to get there.

    Honestly, a protocol analyzer that does not run at bus speeds is perplexing.  It costs time to develop yet brings no value to the customer....

  2. Update:

    I was able to record 100 of the 1Msps 16 bit SPI transactions.  The Waveforms application only took 20 minutes to do this, and it produced a message in red "Samples could be lost.3344874" [sic].  I'll try for 1000 samples next, and let it run over night.  The logic analyzer module works so much better than the protocol module, I am very disappointed that the protocol module, which lured me to purchase the Digital Discovery, was even included in Waveforms at this point as it is completely unusable.

  3. I tried using the logic analyzer using the low speed (DIOs 24, 25, and 26) inputs, and can successfully decode the SPI transactions, though the waveform resolution is terrible.  When I set up the protocol module and click on "receive", the mouse cursor turns to a blue circle, and the Waveforms application's title bar gets a "(Not Responding)" addition, and eventually the application self-terminates.  Really?

    @RayHaynesI totally agree, this software is not ready for prime time, and I would not recommend this product, or ANY Digilent product for that matter, to anyone until Digilent learns how to properly code.

  4. Hello - I can set up a SPI channel in WaveForms' Logic analyzer, and all that works well.  When I try to use the protocol module, however, I can only choose from the non high-speed inputs.  (DIO 24 and up).  As this is a 20MHz SPI clock with an ADC sampling @ 1MSps, yeah I want the high-speed inputs.

    What I am after is dumping about 1000 consecutive SPI transactions to a file for statistical analysis.  Have to say, I'm a little dissappointed in WaveForms.  Close, but no cigar as they say.
