SPI decoder for HP 16700 LA?

[perdrix]

Did anyone ever write one? 

PS I do have a Saleae clone but it is working at its limits ...

Thanks, David

I have not seen an SPI decoder for the 167xx series.  Please post if you find one.

I always thought it would be a worthwhile investment to write a sigrok driver for the 167xx.  The 167xx can gather the raw data and then pass it to sigrok for processing.  That way, the sigrok SPI decoder and large library of higher layer decoders can be leveraged.  And it could be used for more than just SPI, obviously.

The 167xx supports an RPI (Remote Programming Interface) documented here:

  https://www.keysight.com/us/en/assets/9018-40955/user-manuals/9018-40955.pdf

It uses plain ASCII commands, and also supports binary transfer for captured data.  You can telnet to it on port 6500 to play.  Type "help all" for a list of commands in addition to what's in the manual.

It doesn't seem like it would be too complicated to glue this interface to sigrok.
