nidaqmxbase synapps module

[Terry Cornall <Terry.Cornall@synchrotron.org.au>]

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)
