Hey guys,

We’re having trouble with our CompactRIO; specifically, Jaguars are not responsive to data from the driver station. I wrote a piece of LabVIEW code to run the Jaguars either using joystick inputs or using a numerical constant (0.5). However, upon deploying this code to the cRIO, there was no indication that the code was running.

To ensure that the code was in fact running, I wrote a bit of LabVIEW code to set the value of the Jag to 0.5, and then to get the value of the speed controller and compare it to the input. I observed that while the value of 0.5 was being sent to the Jag, I was not getting the same value when I get the output of the speed controller. This leads me to believe that it is a programming error.

I have attached printscreens of the code I am using. It is not changed at all from the default code except for the actual motor code. I have also checked with different Jaguars, breakout boards, and sidecars to no avail. I have also probed the PWM ports manually with a multimeter (can't afford an oscilloscope), it does not read any significant signal on either the power, ground, or signal cables.

Thanks,
Eric
