I'm caught in GPIB compatiblity hell. I had to replace my 9914 card with a 7210 card to get compatibility with some old software. All my own software bit-bangs a 9914 chip in visual basic.
Is there a cookbook to help me convert my 9914 code to 7210 code. I have both the specs, but that doesn't tell me about all the gotchas I'm going to run into in the process. As I recall, I spent weeks on the 9914 code over tiny details that I'd missed or misinterpreted. I need only a very TINY subset of the GPIB functionality, but still got tripped up by the very complex documentation.
I'm also looking for a reference design for a RS-232 to GPIB converter. Should be able to drive one instrument with zero length cable directly from a PIC processor, do most of the processing inside the PIC, then send it out the RS-232. Ideas?
Thanks, mike
