I think one of your diagrams was wrong..
Correct diagram is:
MOSI --> MISO
MISO <-- MOSI

I would like to see the best method to connect an esp to the HPIB interface for full 2 way communication. I am thinking either i2c or RX/TX... Is there a chip that speaks HPIB natively, or should I just program it into the code?

HPIB has 8 data pins and 8 pins that work similar to: DTR, CTS, etc..

I want to take full advantage of those pins and have it know what to do.

I have a HP3438A DVM that I hope to make post data to a MySQL database. and let me change settings remotely.. Other Images (1) eBay Item: 274417844176
