I'm new to c# and to the NI programming. I have a PCIe 6321 DAQmx board. I want to write a buffer/array of values to Dev1/port0:0-7. I can write a single value just fine using WriteSingleSamplePort, but when I try to write 8 data values via WriteMultiSamplePort, all I get out is the last element of the buffer/array. I monitored the output from the PCI card using a logic analyzer.
What am I missing? Should I use a clock with this output? I'd like to control the data generation rate, but I have not gotten that far. I presumed the internal rate generator of the board would be sufficient for the data generation. Additionally, I presume the data should repeat until I tell the board to stop generating.
