I have basically overlayed the two LabWindows examples provided by NI on top of each other (double buffered input/output with internal timing) in order to get continuous input and output with my dio-32hs. however, i continually get error messages, saying that the card has to stop output in order to reallocate resources for input. something tells me that my programming approach may not be the best way, but it might be something else? i know there is a labview example, but if someone could provide one in labwindows, i would appreciate it very much.
