Class | SoftwareServo
Name | ### attach()
Examples |
    import processing.io.*;
    SoftwareServo servo;

    void setup() {
      servo = new SoftwareServo(this);
      servo.attach(4);

      // On the Raspberry Pi, GPIO 4 is pin 7 on the pin header,
      // located on the fourth row, above one of the ground pins
    }

    void draw() {
      // we don't go right to the edge to prevent
      // making the servo unhappy
      float angle = 90 + sin(frameCount / 100.0)*85;
      servo.write(angle);
    }
Description | Attaches a servo motor to a GPIO pin You must call this function before calling write(). Note that the servo motor will only be instructed to move after the first time write() is called. The optional parameters minPulse and maxPulse control the minimum and maximum pulse width durations. The default values, identical to those of Arduino's Servo class, should be compatible with most servo motors.
Syntax |
    .attach(pin)
    .attach(pin, minPulse, maxPulse)
Parameters |
pin | int: GPIO pin
minPulse | int: minimum pulse width in microseconds (default: 544, same as on Arduino)
maxPulse | int: maximum pulse width in microseconds (default: 2400, same as on Arduino)
Returns | void
