Extra Pulse Generated By NI PCIe-8255R When Using Close FPGA VI ReferencePrimary Software: LabVIEW Modules>>FPGA ModulePrimary Software Version: 1.0 Primary Software Fixed Version: N/A Secondary Software: Driver Software>>NI-IMAQdx Hardware: Image Acquisition (IMAQ)>>Digital Image Devices>>PCIe-8255R
Problem: I am generating a pulse train from my NI PCIe-8255R. When I close the FPGA reference to my device it generates an unexpected extra pulse. Why is this happening, and how do I prevent it? Solution: The default setting of the Close FPGA Reference VI is to reset the FPGA. The NI PCIe-8255R generates a digital pulse when the FPGA resets. To prevent the generation of this pulse, right-click on the Close FPGA VI Reference and select Close. Now the FPGA reference will not reset when the FPGA reference is closed, and the PCIe-8255R will not generate an extra pulse.
