A Bumper Switch is created by using the following constructor:

The bumper constructor creates a bumper object in the specified Three Wire Port:

Parameter	Description

void BumperPressed() {
  // The Brain will print that the Bumper Switch was pressed on the
  // Brain's screen.
  Brain.Screen.print("Bumper pressed");
}

int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  // Run BumperPressed when the value of the Bumper Switch is pressed.
  BumperA.pressed(BumperPressed);
}

released()

The released(callback) method calls a function when the bumper switch is released.
