29# How to include the library
30
31First download the library by clicking on the following link: <https://github.com/felis/USB_Host_Shield_2.0/archive/master.zip>.
32
33Then uncompress the zip folder and rename the directory to "USB\_Host\_Shield\_20", as any special characters are not supported by the Arduino IDE.
34
35Now open up the Arduino IDE and open "File>Preferences". There you will see the location of your sketchbook. Open that directory and create a directory called "libraries" inside that directory.
36Now move the "USB\_Host\_Shield\_20" directory to the "libraries" directory.
37
38The final structure should look like this:
39
40* Arduino/
41 * libraries/
42 * USB\_Host\_Shield\_20/
43
44Now quit the Arduino IDE and reopen it.
45
46Now you should be able to go open all the examples codes by navigating to "File>Examples>USB\_Host\_Shield\_20" and then select the example you will like to open.

50# How to use the library
51
52### Documentation
53
54Documentation for the library can be found at the following link: <http://felis.github.com/USB_Host_Shield_2.0/>.
55
56### Enable debugging
57
58By default serial debugging is disabled. To turn it on simply change ```ENABLE_UHS_DEBUGGING``` to 1 in [settings.h](settings.h) like so:
59
60```
61#define ENABLE_UHS_DEBUGGING 1
62```
63
64### Boards
65
66Currently the following boards are supported by the library:
67
68* All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
74The following boards need to be activated manually in [settings.h](settings.h):
75
76* Arduino Mega ADK
77 * If you are using Arduino 1.5.5 or newer there is no need to activate the Arduino Mega ADK manually
78* Black Widdow
79
80Simply set the corresponding value to 1 instead of 0.
81
82### [Bluetooth libraries](BTD.cpp)
83
84The [BTD library](BTD.cpp) is a general purpose library for an ordinary Bluetooth dongle.
85This library make it easy to add support for different Bluetooth services like a PS3 or a Wii controller or SPP which is a virtual serial port via Bluetooth.
86Some different examples can be found in the [example directory](examples/Bluetooth).
87
88The BTD library will also make it possible to use multiple services at once, the following example sketch is an example of this:
93The [Bluetooth HID library](BTHID.cpp) allows you to connect HID devices via Bluetooth to the USB Host Shield.
94
95Currently HID mice and keyboards are supported.
96
97It uses the standard Boot protocol by default, but it is also able to use the Report protocol as well. You would simply have to call ```setProtocolMode()``` and then parse ```HID_RPT_PROTOCOL``` as an argument. You will then have to modify the parser for your device. See the example: <https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/BTHID/BTHID.ino> for more information.
98
99### [SPP library](SPP.cpp)
100
101SPP stands for "Serial Port Profile" and is a Bluetooth protocol that implements a virtual comport which allows you to send data back and forth from your computer/phone to your Arduino via Bluetooth.
102It has been tested successfully on Windows, Mac OS X, Linux, and Android.
103
104More information can be found at these blog posts:
109To implement the SPP protocol I used a Bluetooth sniffing tool called [PacketLogger](http://www.tkjelectronics.com/uploads/PacketLogger.zip) developed by Apple.
110It enables me to see the Bluetooth communication between my Mac and any device.
111
112### PS3 Library
113
114These libraries consist of the [PS3BT](PS3BT.cpp) and [PS3USB](PS3USB.cpp). These libraries allows you to use a Dualshock 3, Navigation or a Motion controller with the USB Host Shield both via Bluetooth and USB.
115
116In order to use your Playstation controller via Bluetooth you have to set the Bluetooth address of the dongle internally to your PS3 Controller. This can be achieved by plugging the controller in via USB and letting the library set it automatically.
117
118__Note:__ To obtain the address you have to plug in the Bluetooth dongle before connecting the controller, or alternatively you could set it in code like so: <https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/PS3BT/PS3BT.ino#L15>.
119
120For more information about the PS3 protocol see the official wiki: <https://github.com/felis/USB_Host_Shield_2.0/wiki/PS3-Information>.
1301. _Richard Ibbotson_ who made this excellent guide: <http://www.circuitsathome.com/mcu/ps3-and-wiimote-game-controllers-on-the-arduino-host-shield-part>
1312. _Tomoyuki Tanaka_ for releasing his code for the Arduino USB Host shield connected to the wiimote: <http://www.circuitsathome.com/mcu/rc-car-controlled-by-wii-remote-on-arduino>
132
133Also a big thanks all the people behind these sites about the Motion controller:
157The library support one Xbox 360 via USB or up to four Xbox 360 controllers wirelessly by using a [Xbox 360 wireless receiver](http://blog.tkjelectronics.dk/wp-content/uploads/xbox360-wireless-receiver.jpg).
158
159To use it via USB use the [XBOXUSB](XBOXUSB.cpp) library or to use it wirelessly use the [XBOXRECV](XBOXRECV.cpp) library.
160
161__Note that a Wireless controller can NOT be used via USB!__
162
163Examples code can be found in the [examples directory](examples/Xbox).
179The [Wii](Wii.cpp) library support the Wiimote, but also the Nunchuch and Motion Plus extensions via Bluetooth. The Wii U Pro Controller is also supported via Bluetooth.
180
181First you have to pair with the controller, this is done automatically by the library if you create the instance like so:
182
183```
184WII Wii(&Btd,PAIR);
185```
186
187And then press 1 & 2 at once on the Wiimote or press sync if you are using a Wii U Pro Controller.
188
189After that you can simply create the instance like so:
190
191```
192WII Wii(&Btd);
193```
194
195Then just press any button on the Wiimote and it will then connect to the dongle.
196
197Take a look at the example for more information: <https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/Wii/Wii.ino>.
