PS4 controller now supported by the USB Host library
I am very pleased to announce that I have now added support for the PS4 controller via Bluetooth. This will allow you to read all the buttons and joysticks with the same API as all the other libraries I have written for the USB Host library.
To get started you should look at the provided example. It shows how to read the different buttons and joysticks.
I still haven’t figured out how to control the light, rumble and read the accelerometer, gyroscope and touchpad, but hopefully I will figure that out soon.
The pairing process for the PS4 controller is a little different than the PS3 controller, as it works like a regular Bluetooth joystick, as you simply make the PS4 controller discoverable by holding down the PS and Share button at the same time. The light will then start to blink rapidly.
After that you should be able to pair with the controller, by creating the PS4BT instance like so:
You should also check out the readme which will always have the newest information available.
The PS4 Bluetooth library actually uses the BTHID library to handle all the Bluetooth communication. This is much more modular and easier to maintain. I will work on making all the Bluetooth classes like that, so it will reduce the footprint of the libraries, but also make it much easier to maintain, as all the L2CAP communication would be handled in only one class.
I still haven’t written a library to use it via USB, but I will do that in the coming weeks, when I have time.
This is all for now. Please leave a comment below if you got any questions and I will answer as quickly as possible.
Update 18. January 2014
A USB version of the library is now also available. It allows you to read the gyroscope, accelerometer and touchpad as well.
Update 22. January 2014
I now also figured out how to read the IMU and touchpad data via Bluetooth. The problem is that the controller does not send out this information via Bluetooth by default.
To enable the full output the code sends out a get feature report. For more information see this excellent Wiki: http://eleccelerator.com/wiki/index.php?title=DualShock_4 by Frank Zhao.
Update 16. February 2014
It is now also possible to control the rumble and light as well. The code was inspired by this Linux driver: https://github.com/chrippa/ds4drv.
