Choose the library file “d2xx.jar”. The D2xxManager class allows access to driver-wide information such as the VID and PID combinations to match with the device information list, and provides APIs to open target devices returning corresponding FT_Device objects. The FT_Device object can perform UART, EEPROM, and Bit mode-related operations to control device status or read/write data. When the device is no longer required, the FT_Device object can be closed with the close() method. The D2xx Java library is fully documented using Javadoc. Information on the D2xx Android library methods, constants, and sub-classes is available in the corresponding Javadoc entry in the sample project’s/doc directory.
