How do I do digital output from PCI-6534 onboard memory?

[douga]

I want to load the memory once (about 1.6 MB) and then output the entire memory once every 10 sec for hours without reloading the memory each time. I am using Visual C++, not LabView. I have the documentation for NI-DAQ 6.9, but can't find anything in it about using the 6534 on-board memory.

Hello,

You can find how to use the onboard memory of the NI-6534 on page 2-9 of the 653x User's Manual
.

In general, you will have to use Set the ND_PATTERN_GENERATION_LOOP_ENABLE to ND_ON
in the Set_DAQ_Device_Info function.

On the function panel for the function Set_DAQ_Device_Info there is no option for ND_PATTERN_GENERATION_LOOP_ENABLE, you have to type it manually and also you have to type the information value. It works, just do not use the D at the end of the ENABLED word from the User's Manual!

Good luck with your application! Hope this information helps.
