Speed control for Jaguars?

[BurtGummer]

Hi everyone!

This is our schools first year participating in any robotic competition, so things have been going pretty rough.

We hadn't been able to get our motors spinning at all, but after hours of troubleshooting, we found that removing the watchdog from the labview project let us turn the motors on and off by the values -1 0 and 1 in the speed input box in the labview program.

However, we cannot control the actual speed of the motors with the code, even though the video "Make a simple motor in 10 minutes" shows variable speed. When we run the motors, we get the slow blinking on the sidecar, but the LEDS on the jaguars go green when they are on, regardless of the blinking LEDs on the sidecar.

I updated both the cRIO image and the Driver revision from the most recent releases.

So, in conclusion, we can turn the motors on and off without speed control when we delete the "Watchdog: Open" from the labview code. If the watchdog is in there, then it will not run the motors at all.

The tutorial had stated to set a constant of "false" for the watchdog, but that option is not present, but I did read that the option was completely taken out and it is automatically false. Is this correct?

Thanks in advance!!
