I have had the U3-LV for a long time but never really used it until today. I got it installed and the firmware updated to the latest revision. LJControlPanel is able to find it and I am able to manipulate the configuration. However, when I attempt to use the SPI C# example, it is unable to open the device. I am getting the LJME_ATTR_LOAD_COMM_FAILURE error when I call LJM.Open(). Here is how I am making the call:
LJM.OpenS("ANY", "ANY", "ANY", ref handle);
I have also tried:
LJM.Open(LJM.CONSTANTS.dtU3, LJM.CONSTANTS.ctUSB, "ANY", ref handle);
with the same results. We are attempting to use the LabJack as a way to communicate directly with a SPI peripheral we are not sure is functioning properly with a new board design. Any pointers / assistance is greatly appreciated.
