Im having a little bit of a problem with an interrupt in the waveform im reading as an input.This doesn’t appear to be a typical windows based interrupt but I’m guess it caused by a mistake I made.The interrupt occurs every 7 seconds without fail, and lasts about a half second.I can post a screen capture movie if anyone wants to see it and will attach a copy of the code.
This labview program runs a loading machine (motor which runs off controlled force, not the more common position control).There is an analog output of a DAQ card (pci 6014) which determines the force driven by the motor controller.So by inputting a sinusoid into the DAQ, I can then read back a force mirroring the analog input via load cell. So after about 7 reps at 1htz, I get an interrupt in the force being read back from the load cell.It always occurs in the exact same spot of the waveform when it occurs (every 7 reps).The position of the interrupt within the waveform can however, change places in the waveform if i stop and restart the program. Changing the loading frequency will show the interrupt will just occur after twice as many reps.
There is no disruption of the plot of the signal which is controlling the waveform (sent to the D to A of pci 6014).
This is labview: 2009 32bit, patched v3
