This is Arduino library for WiiRemote Bluetooth stack which supports minimum HCI and L2CAP layer for HID profile.

== First of all ==
This program is based on <wiiblue.pde> which is developed by Richard Ibbotson.
This program also needs MAX3421E and USB libraries for Arduino written by Oleg Mazurov.
The source codes can be grabbed from <https://github.com/felis/USB_Host_Shield>.


== Hardware Requirement ==
    * Arduino
    * USB Host Shield
    * USB Bluetooth Device


== Software Requirement ==
    * MAX3421E and USB library for Arduino written by Oleg Mazurov


== GNU GPL ==

== Usage ==

=== Modify USB Device Descriptors ===
The values of CSR_VID and CSR_PID described in WiiRemote.h need to be modified
to match descriptors of USB Bluetooth Device to be used.


== WiiRemote Class ==

=== Methods ===
    * void init(void)

    * void task(void (*pFunc)(void))

    * uint8_t getStatus(void)
            This returns unsigned int as the status of USB Bluetooth Device and
            WiiRemote connection. Bit field shows as follows:
            bit 0:  WIIREMOTE_STATE_USB_AUTHORIZED
                    USB BT Device is authorized as the library expects.
            bit 1:  WIIREMOTE_STATE_USB_CONFIGURED
                    USB BT Device is plugged into the USB port on the Shield.
            bit 2:  WIIREMOTE_STATE_CONNECTED
                    WiiRemote has been connected to USB BT Device.
            bit 3:  WIIREMOTE_STATE_RUNNING
                    WiiRemote has been established L2CAP connection.

    * void setBDAddress(uint8_t *bdaddr, int size)

    * void setBDAddressMode(eBDAddressMode mode)
            This selects how to acquire BD_ADDR to establish HCI connection.
            The mode can be set:
                BD_ADDR_FIXED:    Use specified BD_ADDR set by setBDAddress().
                BD_ADDR_INQUIRY:  Discover BD_ADDR of WiiRemote to be connected.

    * void getBDAddress(uint8_t *bdaddr, int size)

    * uint8_t setLED(uint8_t led)
            This turns on/off LEDs of WiiRemote. setLED(0x0) turns off all LEDs,
            setLED(0x10) turns on LED1 and setLED(0xf0) turns o all LEDs.
            These enum can be used:
                WIIREMOTE_LED1 = 0x10,
                WIIREMOTE_LED2 = 0x20,
                WIIREMOTE_LED3 = 0x40,
                WIIREMOTE_LED4 = 0x80,

    * bool buttonPressed(uint16_t button)
            This returns the state of WiiRemote button specified in the call.
            True if the button pressed. Buttons are:
                WIIREMOTE_LEFT  = 0x0001,
                WIIREMOTE_RIGHT = 0x0002,
                WIIREMOTE_DOWN  = 0x0004,
                WIIREMOTE_UP    = 0x0008,
                WIIREMOTE_PLUS  = 0x0010,
                WIIREMOTE_TWO   = 0x0100,
                WIIREMOTE_ONE   = 0x0200,
                WIIREMOTE_B     = 0x0400,
                WIIREMOTE_A     = 0x0800,
                WIIREMOTE_MINUS = 0x1000,
                WIIREMOTE_HOME  = 0x8000,

    * bool buttonClicked(uint16_t button)
            This checkes whether a specified WiiRemote button is clicked.
            True if the button clicked. Buttons are the same as above.

=== Member Variables ===
    * Report_t Report


== Hint ==
Hints from PS3 and Wiimote game controllers thread in Circuit@Home.
    - Bluetooth 1.x seems not work on this library.


== ACKNOWLEDGEMENT ==
I appreciate the gread codes developed by Richard and Oleg :-)
