Hi Terry,
 
Cool! I wasn't aware anyone was really using my module!!! I don't currently have a good NI hardware setup and I haven't build the software for ages - but I'll have a quick look at the code and see if anything comes to mind - do you get any sort of error messages on the shell? What hardware are you using?
 
The software was picked up a while ago by Heinrich du Toit (who is no longer working with EPICS, as I understand it) - I imagine you are using the version he made several additions to.
 
I have been meaning to clean up the code for ages as it is currently in a bit of a messy state...
 
Cheers,
Ulrik

Hi All.

I’m using  NIDAQmxBase written by Ulrik Pederson in 2007 in an Epics application driving a National Instruments card.

It all works, but if I open two ports to the card, one for DAC and the other for ADC, and I write fast enough to the DAC port, I get buffer underflows on the ADC port.

Has anyone found a fix for this? (It might be to do with the National Instruments drivers, of course, which are nidaqmxbase v 3.2.0 and NIKAL 1.7)
