Issues With Motor Groups

Programming Support VEXcode Pro V5 Text Tech Support
#1

I am currently having an issue using motor groups. Using the competition template I have the motor groups initialized in the robot-config.cpp file. Then within the vexcodeInti function I am defining the motors that will be used in the motor group and then re defining the motor group.

An Example:

motor_group leftMotors;

void vexcodeIniti(void) {
motor leftWheelMotorA = motor(PORT1, ratio18_1, true);
motor leftWheelMotorB = motor(PORT2, ratio18_1, true);

leftMotors =motor_group(leftWheelMotorA, leftWheelMotorB);
}

Later in the code I set the leftMotors velocity and start spinning. the code compiles fine but the physical motors do not run when I run the spin function on the motor group. Any help on how to fix this would be greatly appreciated.

#2

should be

motor_group leftMotors = motor_group(leftWheelMotorA, leftWheelMotorB);

In addition, take the

motor leftWheelMotorA = motor(PORT1, ratio18_1, true);
motor leftWheelMotorB = motor(PORT2, ratio18_1, true);

should not be inside the

void vexcodeInit (void) {
//nothing to initialize
}

section on robot-config.cpp.
Hope that helps!
