Variables hanging?

[jgrindle]

Hey y'all,

If you search these forums frequently, you'll notice my last post was about a kiwi drive system. We are adding a Frisbee shooter to the top of it (for those that must know, it will be an inline shooter(using 6 inch wheels(direct driven by a CIM and a Mini-CIM))). I created speed selector for it using the D-Pad (code shown below)

void Shooter::SpeedChanger(int dir){
	switch(dir){
	case 0:
		if (change == false){
			if (sped < 2){
				sped = sped + 1;
				printf("Speed up \n");
				change = true;
			}
		}
		break;
	case 180:
		if(change == false){
			if(sped > 0){
				sped = sped - 1;
				printf("Speed Down \n");
				change = true;
			}
		}

		break;
	default:
		printf("Nothing\n");
		change = false;
		break;
	}
	printf("%d", sped);
	printf("\n");

}

If I get crazy with button pressing, or just wait a while, the code will just hang. The only way to get it out of this hanging state, is to disable it, then re-enable it. I have a video of it when working. When it hangs, it will only stay on the one variable, that it last was on. The code for driving on the other hand, will not hang.
