Problems programing NXT using Labview

[robodude82]

I posted this in the main Labview discussion board before I found this one, I hope someone can help me.

Hello  I'm starting a robotics team where I work, high school so I hope my  question isn't to rudimentary for this forum. I built the basic tetrix  base but can't get the programming started. The robot essentially runs off of a lego mindstorms NXT module. When I try to test the sensors, or  motors, nothing works, I can't even tell if they are showing up or not.  I see them but can't tell if they're active. When I try to use the the  schematic editor to test everything nothing seems to work. I can change  the parameters, eg. motor direction, but it doesn't seem to affect the  sensors, or motors plugged into the NXT. When I wave my hand in front of  the ultrasonic sensor nothing changes, when I push the plunger on the  touch sensor the values on the schematic editor don't change. I don't  know if this has anything to do with it but I keep changing batteries  but the battery indicator keeps showing the same level of power, almost  dead.

Hello;

You are right, that could be the reason why the NXT brick does not read any of the sensors of outputs any voltage to the motors. Have you tried connecting the brick to an AC adapter? Also, have you tried using any other NXT bricks with this computer? Just to verify that the problem is the brick and not the software set up.
