### PS4 Library
|
||||
|
||||
This is the [PS4BT](PS4BT.cpp) library. It works with the official Sony PS4 controller via Bluetooth.
|
||||
The PS4BT library is split up into the [PS4BT](PS4BT.h) and the [PS4USB](PS4USB.h) library. These allow you to use the Sony PS4 controller via Bluetooth and USB.
|
||||
|
||||
The [PS4BT.ino](examples/Bluetooth/PS4BT/PS4BT.ino) example shows how to easily read the buttons and joysticks on the controller.
|
||||
The [PS4BT.ino](examples/Bluetooth/PS4BT/PS4BT.ino) and [PS4USB.ino](examples/PS4USB/PS4USB.ino) examples shows how to easily read the buttons and joysticks on the controller via Bluetooth and USB respectively.
|
||||
|
||||
I still have not figured out how to read the touchpad, turn rumble on and off and set the color of the light, but hopefully I will figure that out soon.

|

Before you can use the PS4 controller you will need to pair with it.
|
||||
Also the gyro, accelerometer and touchpad values are still only available via USB at the moment.
|
||||
|
||||
Simply create the BTHID instance like so: ```BTHID bthid(&Btd, PAIR);``` and then hold down the PS and Share button at the same time, the PS4 controller will then start to blink rapidly indicating that it is in paring mode.

|

It should then automatically pair the dongle with your controller. This only have to be done once.
