## Class D2xxManager

- java.lang.Object
- - com.ftdi.j2xx.D2xxManager

-     public class D2xxManager
      extends java.lang.Object

  A management class for connected FTDI devices. Use `getInstance(Context)` to get a copy of D2xxManager; use `createDeviceInfoList(Context)` method to scan current connected FTDI devices, then open target device via a suitable open API.

    - #### isFtDevice

          public boolean isFtDevice(UsbDevice dev)

      This queries if a plugged-in USB device is a valid FT_Device
      Parameters:
        `dev` - The UsbDevice get from ACTION_USB_DEVICE_ATTACHED broadcast.
      Returns:
        If the plugged in USB device is ascertained to be a valid FT device, the query returns a ¡¥true¡¦ value

    - #### getInstance

          public static D2xxManager getInstance(Context parentContext)
                                         throws D2xxManager.D2xxException

      This method initialises an application, obtaining a value of D2xx device manager.
      Parameters:
        `parentContext` - The calling activity must pass the application Context into this function.
      Returns:
        An instance of `D2xxManager` device manager.
      Throws:
        `D2xxManager.D2xxException`

    - #### setVIDPID

          public boolean setVIDPID(int vendorId,
                          int productId)

      This allows a custom VID and PID combination within the internal device list table. This loads the drivers for the specified VID and PID combination. NOTE: The driver supports a limited set of VID and PID matched devices. VID : 0x0403 , FTDI PID : 0x6015 , X Series Device PID : 0x6014 , FT232H Device PID : 0x6011 , FT4232H Device PID : 0x6010 , FT2232 or FT2232H Device PID : 0x6001 , 232AM, FT232B or FT232R PID : 0x6006 , Direct Driver Recovery PID PID : 0x601C , FT4222 PID : 0xFAC1 , USB Instruments PS40M10 PID : 0xFAC2 , USB Instruments DS1M12 PID : 0xFAC3 , USB Instruments DS100M10 PID : 0xFAC4 , USB Instruments DS60M10 PID : 0xFAC5 , USB Instruments EasySYNC LA100 PID : 0xFAC6 , USB2-F-7x01 CANPlus Adapter PID : 0x6012 , ES001H PID : 0x1025 , Macraigor - customer request PID : 0x0001 , Keith Support Request 8/10/04 PID : 0x6017 , Additional VID/PID To use this driver with other VID and PID combinations, the `setVIDPID(int, int)` function is a pre-requisite. `openByIndex(Context, int, com.ftdi.j2xx.D2xxManager.DriverParameters)`, `openByLocation(Context, int, com.ftdi.j2xx.D2xxManager.DriverParameters)`, `openBySerialNumber(Context, java.lang.String, com.ftdi.j2xx.D2xxManager.DriverParameters)`, `openByDescription(Context, java.lang.String, com.ftdi.j2xx.D2xxManager.DriverParameters)`, `createDeviceInfoList(Context)`.
      Parameters:
        `vendorId` - The vendor ID that the driver aligns with
        `productId` - The product ID that the driver aligns with
      Returns:

    - #### createDeviceInfoList

          public int createDeviceInfoList(Context parentContext)

      This method builds an internal device information list and returns the number of D2XX devices connected to the system. The list contains information about both unopened and opened devices. Device information may be retrieved via the `getDeviceInfoList(int, com.ftdi.j2xx.D2xxManager.FtDeviceInfoListNode[])` or `getDeviceInfoListDetail(int)` methods. Remarks: An application can use this function to ascertain the number of devices attached to the system. The application allocates space for the device information list and retrieves the list using `getDeviceInfoList(int, com.ftdi.j2xx.D2xxManager.FtDeviceInfoListNode[])` or `getDeviceInfoListDetail(int)` methods. If the devices connected to the system change, the device info list will not be updated until `createDeviceInfoList(Context)` is called again.
      Parameters:
        `parentContext` - The calling activity must pass the application Context into this function.
      Returns:
        The number of devices represented in the device information list. This is used to ensure that sufficient storage for the device list is returned by `getDeviceInfoList(int, com.ftdi.j2xx.D2xxManager.FtDeviceInfoListNode[])`.

    - #### getDeviceInfoList

      This method returns the device list created with a prior call to `createDeviceInfoList(Context)`. The list contains all available information for all of the available devices at the time that `createDeviceInfoList(Context)` was called. Note that the flags element of each `D2xxManager.FtDeviceInfoListNode` object in the list is a bit-mask of `FT_FLAGS_OPENED` and `FT_FLAGS_HI_SPEED`. Remarks: This function should only be called after calling `createDeviceInfoList(Context)`. If the devices connected to the system change, the device info list will not be updated until `createDeviceInfoList(Context)` is called again. Location ID information is not returned for devices that are open when `createDeviceInfoList(Context)` is called. Information is not available for devices which are open in other processes. The Flags parameter of the `FT_FLAGS_OPENED` indicate that the device is open, but other fields will be unpopulated.
      Parameters:
        `numDevs` - The number of devices represented in the device information list.
        `deviceList` - An array of `D2xxManager.FtDeviceInfoListNode`. That contains information on all available devices after a successful call..

NOTE:This function is to be called after calling `createDeviceInfoList(Context)`. The device info list is not updated where changes are made to the connected devices until `createDeviceInfoList(Context)` is called again. The index value is zero-based.
      Parameters:
        `index` - An index of the information pertaining to the devices in the list.
      Returns:
        A `D2xxManager.FtDeviceInfoListNode` object containing the information available for the device specified index in the list. NULL for error.
