Post Drive Straight code?
Is there anybody with a drive straight code for robotc with encoders? my motors are unequally matched and im wondering if there is a way to use encoders to make sure they go the same speed. Any help would be appreciated :)

You could do something like this:
int diff;
nMotorEncoder[leftMotor] = 0;
nMotorEncoder[rightmotor] = 0;
while (true)
    diff = (nMotorEncoder[rightMotor] - nMotorEncoder[leftMotor])/scaleFactor;
    motor[leftMotor] = 50 + diff;
    motor[rightMotor] = 50 - diff;

Or you can use the built-in motorSync function. I don't have RobotC in front of me, so I don't remember the syntax.
