Tessel servo module with Johnny-Five

[Henrose]

Hello,

I would like to control some continuous servos with a Tessel 2 and the Tessel servo module servo-pca9685. I want to make use of the Johnny-Five Kit. But I am not sure how to initialize the servo instance in my source code.

Currently my code looks like this:

  // Initialize the servo instance
  var servo = new five.Servo.Continuous({
    controller: "PCA9685",
    port: "A",
    address: 0x73,
    pin: 1,
  });

  servo.cw(1);

But my servo on channel 1 is not moving at all.

My servo module is connected to port A, that's for sure. But all the other parameters for the servo constructor are not completely clear to me.
- is the controller "PCA9685" correct ?
- what about the address? Which do I have to use? The 0x73 is an address which is given in an example on the Johnny-Five website
- do I have specify a certain pin, when using a port ? If so, which?
- how can I select one of the 15 channels on the Tessel servo-pca9685 module?

Thank you in advance for any help.
