What about embedding an ISA-bus GPIB card?
I have a similar problem except that I want to control
the GPIB directly from the Microcontroller pins.
I only need a TINY subset of GPIB to control ONE
instrument talker/listener. uC is always controller.
No, I can't use any other interface cause that's what the Power supply has.
No, I can't use a NI card, 'cause that's what I'm replacing.
I'm too lazy to decipher the 488 spec. I need only a tiny part, but
is't hard to figure out exactly which tiny part. Would be nice to find some
already-done boiler plate code. I'd prefer PIC, cause that's what I'm
set up for.
Doing GPIB with a GPIB controller chip is a lot easier.
I wrote a VB6 class module that implements a tiny subset of GPIB
by bit-banging a 9914 chip.
Also have a class module for a TEK PS2521G Programmable power supply
that uses it.
It's horrible code, but it does work.
