USB Host Library Rev.2.0

The code is released under the GNU General Public License.

Summary

This is Revision 2.0 of MAX3421E-based USB Host Shield Library for AVR's.

Project main web site is: http://www.circuitsathome.com.

Some information can also be found at: http://blog.tkjelectronics.dk/.

The shield can be purchased at the main site: http://www.circuitsathome.com/products-page/arduino-shields or from TKJ Electronics: http://shop.tkjelectronics.dk/product_info.php?products_id=43.

How to include the library

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:

  • Arduino/
    • libraries/
      • USB_Host_Shield_20/

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.

How to use the library

Documentation

Documentation for the library can be found at the following link: http://felis.github.com/USB_Host_Shield_2.0/.

Enable debugging

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

Boards

Currently the following boards are supported by the library:

  • All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
  • Teensy (Teensy 1.0, Teensy 2.0 and Teensy++ 2.0)
  • Balanduino
  • Sanguino
  • Black Widdow

The following boards need to be activated manually in settings.h:

  • Arduino Mega ADK
  • Black Widdow

Simply set the corresponding value to 1 instead of 0.

Bluetooth libraries

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 will also make it possible to use multiple services at once, the following example sketch is an example of this: https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/PS3SPP/PS3SPP.ino

SPP 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.

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.

PS3 Library

These libraries consist of the PS3BT and PS3USB. These libraries allows you to use a Dualshock 3, Navigation or a Motion controller with the USB Host Shield both via Bluetooth and USB.

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 plugging the controller in via USB and letting the library set it automatically.

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#L12.

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:

  1. Richard Ibbotson who made this excellent guide: http://www.circuitsathome.com/mcu/ps3-and-wiimote-game-controllers-on-the-arduino-host-shield-part
  2. 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:

Xbox Libraries

The library supports both the original Xbox controller via USB and the Xbox 360 controller both via USB and wirelessly.

Xbox library

The XBOXOLD class implements support for the original Xbox controller via USB.

All the information are from the following sites:

Xbox 360 Library

The library support one Xbox 360 via USB or up to four Xbox 360 controllers wirelessly by using a Xbox 360 wireless receiver.

To use it via USB use the XBOXUSB library or to use it wirelessly use the XBOXRECV library.

Note that a Wireless controller can NOT be used via USB!

Examples code can be found in the examples directory.

Wii library

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:

WII Wii(&Btd);

Then just press any button any button on the Wiimote and it will connect to the dongle.

Take a look at the example for more information: https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/Wii/Wii.ino.

FAQ

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.
