Thanks for your answer.
I do have the CVI\Samples\Daq directory. I have looked at the 82C55
examples. That's fine. I also have played with the single example
found at the NI web site: DIO-96 Event8.prj
What I don't have is a Daq6508 header file similar to page 15 on App
Note 131 which only defines PORT/CONTROL bits of a single 82C55 on a
DIO-24. The Daq6508 has four 82C55's.
The NI-DAQ User manual (pp. 3-55-75) is quite detailed, but does not
mention using the Daq6508, even though I understand many of the DI/DO
routines probably apply, given the correct instructions.
The DAQ area is new to me, I've been using CVI/GPIB HP Timer/Keithley
DMM and an old HP 3497A scanner (which I wrote a specific driver)
quite successfully. The finished test program perform
s a calibration
procedure on an analog module which has no trim pots. Instead, the
resulting CAL data(bias/offset etc) is written to EEPROM. The host
system applies the CAL data while using the module's raw output.
many regards to NI support
