Re: motors not running...
So, the issue you said is that "there are times when code will compile and download but appear to not run"
What do you mean the code doesn't appear to run?
None of the motors move? The screen and buttons don't respond? Variables don't change in your code?
If you have an LCD Screen (and aren't doing this already), try making some basic code that will react when you press a button. (I.E. Make the screen backlight go on when you hit the center LCD button, and make it go off when you let go)
Now for the dumb questions: (take them or leave them, you don't have to do all
Have you made sure the Mastercode is up to date?
Is the ROBOTC firmware up to date?
Is the robot power switch turned on when you try to run the code? (because the code will run but motors won't move if it's plugged into a computer via usb, but switched off)
Do you have a fresh battery? (~8V on a voltometer)
Do you have a fresh backup battery?
Can you post a video showing this happening?
Have you tried running the code with the Joystick and the Cortex linked over VEXnet?
Have you tried programming with a different computer?
