Possible Case/Break problems, need help.

So I’m in a bit of a dilemma, I can’t seem to understand why my user control select function for my LCD won’t work. Every time I try to select anything, it switches to “Single control” in the usercontrol phase regardless; although, through testing my auton select is functioning. Please help I’m pretty sure I’m going crazy. Code in the link.


task singleController()
{
	while(true)
	{
		motor[LL] = vexRT[Ch2];
		motor[RL] = vexRT[Ch2];
		motor[D1] = (vexRT[Ch3] + vexRT[Ch4])/2;
		motor[D2] = (vexRT[Ch3] - vexRT[Ch4])/2;
	}
	if(vexRT[Btn6U]==1)
	{
		motor[SK]=127;
	}
	else(motor[SK]=0);
	if(vexRT[Btn6D]==1)
	{
		motor[SK]=-127;
	}
	else(motor[SK]=0);

#2

you are missing a “break” in the initial switch statement so you fall through to the “default” condition and set driver as 0 again. The singleController and doubleController tasks also have issues, put the if statements inside the while loops.

#3

How would this be set up? Once again I’m sorry for the lack of knowledge, I just started with LCD functions and such.

#4

Wait, just found it, lol.

#5

Your tasks are also problematic. Notice how the if statements for the buttons are not in the while loop.
Also,


else(motor[sk]=0);

should be


else { 
motor[sk] = 0; 
}
