This is Revision 2.0 of MAX3421E-based USB Host Shield Library for AVR's.
Project main web site is: http://www.circuitsathome.com.

First download the library by clicking on the following link: https://github.com/felis/USB_Host_Shield_2.0/archive/master.zip.
Then uncompress the zip folder and rename the directory to "USB_Host_Shield_20", as any special characters are not supported by the Arduino IDE.
Now 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. Now move the "USB_Host_Shield_20" directory to the "libraries" directory.
The final structure should look like this:
Now quit the Arduino IDE and reopen it.
Now 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.
For more information visit the following site: http://arduino.cc/en/Guide/Libraries.
Documentation for the library can be found at the following link: http://felis.github.com/USB_Host_Shield_2.0/.
By default serial debugging is disabled. To turn it on simply change
ENABLE_UHS_DEBUGGING to 1 in settings.h like so:
#define ENABLE_UHS_DEBUGGING 1
Currently the following boards are supported by the library:
- All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
- Arduino Due
- If you are using the Arduino Due, then you must include the Arduino SPI library like so:
#include <SPI.h>in your .ino file.
- Teensy (Teensy++ 1.0, Teensy 2.0, Teensy++ 2.0, and Teensy 3.x)
- Note if you are using the Teensy 3.x you should download this SPI library as well: https://github.com/xxxajk/spi4teensy3. You should then add
#include <spi4teensy3.h>to your .ino file.
- Black Widdow
The following boards need to be activated manually in settings.h:
- Arduino Mega ADK
- If you are using Arduino 1.5.5 or newer there is no need to activate the Arduino Mega ADK manually
- Black Widdow
Simply set the corresponding value to 1 instead of 0.
The BTD library is a general purpose library for an ordinary Bluetooth dongle. This 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. Some different examples can be found in the example directory.
The BTD library also makes it possible to use multiple services at once, the following example sketch is an example of this: PS3SPP.ino.
The Bluetooth HID library allows you to connect HID devices via Bluetooth to the USB Host Shield.
Currently HID mice and keyboards are supported.
It 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: BTHID.ino for more information.
The PS4 library also uses this class to handle all Bluetooth communication.
For information see the following blog post: http://blog.tkjelectronics.dk/2013/12/bluetooth-hid-devices-now-supported-by-the-usb-host-library/.
SPP 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. It has been tested successfully on Windows, Mac OS X, Linux, and Android.
Take a look at the SPP.ino example for more information.
More information can be found at these blog posts:
To implement the SPP protocol I used a Bluetooth sniffing tool called PacketLogger developed by Apple. It enables me to see the Bluetooth communication between my Mac and any device.
The PS4BT.ino and PS4USB.ino examples shows how to easily read the buttons, joysticks, touchpad and IMU on the controller via Bluetooth and USB respectively. It is also possible to control the rumble and light on the controller and get the battery level.
Before you can use the PS4 controller via Bluetooth you will need to pair with it.
Simply create the PS4BT instance like so:
PS4BT PS4(&Btd, PAIR); and then hold down the Share button and then hold down the PS without releasing the Share button. 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.
For information see the following blog post: http://blog.tkjelectronics.dk/2014/01/ps4-controller-now-supported-by-the-usb-host-library/.
Also check out this excellent Wiki by Frank Zhao about the PS4 controller: http://eleccelerator.com/wiki/index.php?title=DualShock_4 and this Linux driver: https://github.com/chrippa/ds4drv.
In 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 first plugging in the Bluetooth dongle and wait a few seconds. Now plug in the controller via USB and wait until the LEDs start to flash. The library has now written the Bluetooth address of the dongle to the PS3 controller.
Finally simply plug in the Bluetooth dongle again and press PS on the PS3 controller. After a few seconds it should be connected to the dongle and ready to use.
Note: You will have to plug in the Bluetooth dongle before connecting the controller, as the library needs to read the address of the dongle. Alternatively you could set it in code like so: PS3BT.ino#L20.
For more information about the PS3 protocol see the official wiki: https://github.com/felis/USB_Host_Shield_2.0/wiki/PS3-Information.

A special thanks go to the following people:
- Richard Ibbotson who made this excellent guide: http://www.circuitsathome.com/mcu/ps3-and-wiimote-game-controllers-on-the-arduino-host-shield-part
- 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
Also a big thanks all the people behind these sites about the Motion controller:
The library supports both the original Xbox controller via USB and the Xbox 360 controller both via USB and wirelessly.
The XBOXOLD class implements support for the original Xbox controller via USB.
All the information are from the following sites:
The library support one Xbox 360 via USB or up to four Xbox 360 controllers wirelessly by using a Xbox 360 wireless receiver.
Note that a Wireless controller can NOT be used via USB!
Examples code can be found in the examples directory.
Also see the following blog posts:
All the information regarding the Xbox 360 controller protocol are form these sites:
The Wii library support the Wiimote, but also the Nunchuch and Motion Plus extensions via Bluetooth. The Wii U Pro Controller is also supported via Bluetooth.
First you have to pair with the controller, this is done automatically by the library if you create the instance like so:
WII Wii(&Btd, PAIR);
And then press 1 & 2 at once on the Wiimote or press sync if you are using a Wii U Pro Controller.
After that you can simply create the instance like so:
Then just press any button on the Wiimote and it will then connect to the dongle.
Take a look at the example for more information: Wii.ino.
Also take a look at the blog post:
The Wii IR camera can also be used, but you will have to activate the code for it manually as it is quite large. Simply set
ENABLE_WII_IR_CAMERA to 1 in settings.h.
The WiiIRCamera.ino example shows how it can be used.
All the information about the Wii controllers are from these sites:
- The old library created by Tomoyuki Tanaka: https://github.com/moyuchin/WiiRemote_on_Arduino also helped a lot.
When I plug my device into the USB connector nothing happens?
- Try to connect a external power supply to the Arduino - this solves the problem in most cases.
- You can also use a powered hub between the device and the USB Host Shield. You should then include the USB hub library:
#include <usbhub.h>and create the instance like so:
