A Swift driver for the PCA9685 PWM controller over I2C, using SwiftyGPIO.

## Getting Started

A simple example looks like this:

```

// It doesn't really matter what Raspberry Pi Board you use.

// C.H.I.P. should also work.

let pca9685 = PCA9685(supportedBoard: .RaspberryPiPlusZero)

// This sets the frequency for all channels

// Range: 24 - 1526 Hz

pca9685.frequency = 1440 // Hz

// Can set an individual channel's on and off steps.

// Range: 0 - 4095 Steps

// Example: ~50% Duty Cycle

pca9685.setChannel(0, onStep: 0, offStep: 2048)

// Or all channels at once

pca9685.setAllChannels(onStep: 0, offStep: 0)

```
