Re: Speed control for Jaguars?

Well, still no dice.

Recalibrating should only be necessary is we are using the joysticks right? We are just running it on the computer for now, with a direct ethernet connection to DS. When running the program, you should be able to increase or decrease the integer value on a speed control box on the screen. 1 is full on, 0 is off, -1 is reverse, but we have no control of the speed. Like I said, we had to delete the watchdog to even get the motors to have any kind of response at all.

What's odd is that when the watchdog is in the code, outside the while loop, it isn't wired to anything. I don't know if it should be or not, and to where. The tutorial video does not show it getting wired anywhere. Please keep in mind, this is the first time I've even worked with any visual programming tool, let alone labview.

The program we wrote in labview is extremely simple. It is this exact one seen in the video found here http://zone.ni.com/devzone/cda/tut/p/id/7977

We will be taking the system up to a shop on friday and saturday to see if they can help us......but time is running out! Then again, we just go the robot parts last week.......

Thanks!
