bool interfered = false;

drive_mode_get()

Returns the current drive mode that the task is running. Returns ez::DISABLE, ez::SWING, ez::TURN, ez::DRIVE.

Prototype

void autonomous() {
  chassis.pid_drive_set(12, DRIVE_SPEED);
  chassis.pid_wait();

  if (chassis.interfered)
    chassis.drive_mode_set(ez::DISABLE);
  
  if (chassis.drive_mode_get() == ez::DISABLE) {
    chassis.drive_set(-127, -127); // Run drive motors myself
    pros::delay(2000);
    chassis.drive_set(0, 0);
  }
}

Example

e_mode drive_mode_get();

drive_tick_per_inch()

Returns the conversion between raw sensor value and inches.

Prototype

void initialize() {
  printf("Tick Per Inch: %f\n", chassis.drive_tick_per_inch());
}

Example

double drive_tick_per_inch();

Misc.

pid_wait()

Locks the code in place until the drive has settled. This uses the exit conditions from the PID class.

Prototype

void autonomous() {
  chassis.drive_imu_reset(); 
  chassis.drive_sensor_reset(); 
  chassis.drive_brake_set(MOTOR_BRAKE_HOLD); 

  chassis.pid_turn_set(90, 110);
  chassis.pid_wait();

  chassis.pid_turn_set(0, 110);
  chassis.pid_wait();
}

Example

void pid_wait();
