ServoMotor I2C module

[rezza72]

I want to control a ServoMotor with THIS module:

I asked a question before and they said I should use THIS code.

But I have a problem. This code seems to be not applied to that module. Because in the code, one of the pins of raspberry prepares to send the signal to the module:

private final static int DEFAULT_PIN = 25;

While this module has two pins to receive a signal. (SDA & SCL) I think the code is for PWM modules. But the module has I2C.

How should I use the code for my module?
