This program is not working. I compile and download and it runs the autonomous mode, but as soon as it finishes what I need the robot to do there, the controler doesn't start working. I need help as soon as possible!!!

You need a while(true) loop around your remote control code. A side note, this in in the FTC forums. I'm sure a mod will move it soon, but just remember to post VEX questions in the "ROBOTC for Cortex and PIC" forum next time. Also, to make your code more readable and preserve formatting, you can put your code in the tags next time.

Thank you! And sorry. I'll remember that next time

Also, don't cross post the same question to multiple sub forums. It also helps to put something a little more descriptive than "Help!!" in your subject line. Most people who come here need help and as you can well imagine, having a 1000 threads all named "Help!!" is anything but helpful. A good subject line is more likely to attract the people who know something about your problem than a non-descript one. It's like walking into a room full of people who are all very good at different things and saying "I need help" and not saying what the issue is. Do you think they're all going to ask you what the problem is? Not likely! If you walk into the room and say "Hey, I have some issues with X", the two people who know something about X will come to you and say "Tell us more about the issue you're having." Do you see what I mean?

So in short:

• Don't post the same question to multiple sub forums
• Everyone who asks questions in here would like to be helped as soon as possible. Adding exclamation points does not make us help you any faster.
• Use short and descriptive subject lines
• Wrap your code in tags for readability

That's all

my robot c and cortex and pic brain, started smoking through one of the ports, not the USB nor the battery, but from the brain the port that looks like a phone-line, what connections i had was my controller to my brain using an a to a cable, both had battery's, one may or may not have been almost dead. i have no way of knowing, but the brain battery had 7 volts measured by a (don't know the name) volt measure. any idea why? if any please respond quickly.

I suggest asking this over here That site deals more with hardware q's.
