VNC2 Android Open Accessory to USB Bridge Example
4th July 2014
FTDI have released a Vinculum II source code project to compliment the FT311/FT312 USB to UART, SPI, I2C, PWM, GPIO solutions.
This example describes how to use the Vinculum II (VNC2) to host an Android Open Accessory USB port and bridge to another USB peripheral e,g, the FT232.
The user can take this starter project to get started with their own specific application and add USB accessories to their Android platform.
FTDI have released a UART Terminal application based on their JAVA D2xx driver for use on the Android platform. This application supports all the FTDI to UART devices such as FT230X, FT231X, FT234XD, FT232R and FT232H. The application will allow for configuring the UART interface and transferring data in or out of the Android device.
The application is available from the Google play store here with a user manual, AN_242 available here
Source code is available here
Alternatively the apk may be downloaded here for direct installation.
Launch: FT312D - USB Host Chip
22nd April 2013
The FT312D Android host IC is launched today, providing an instant bridge from your Android USB port(B) to peripheral hardware over UART.
Following on from the success of the FT311D Android Open Accessories host device, the FT312D is a dedicated Android Open Accessory USB host to UART bridge with enhanced buffering and performance.
The device is available in 32 pin LQFP and QFN packages with support for extended temperature ranges of -40°C to 85°C.
Also included in the launch of the FT312D, are Android software examples allowing for rapid test and creation of new and exciting applications.
The FTDI Chip Android Open Accessory HyperTerm Utility is available for download on Google Play.

Announcing Java D2XX Android Driver Availability
7th February 2013
The Java D2XX driver supporting USB host class library model is available free of charge from FTDI Chip (Download full press release in English or in Chinese). The driver supports FTDI’s full complement of USB bridge, slave chips including R Chips(232R/245R), H- Series (USB2.0 Hi-Speed), and the X-Chip Series for Android v3.2 or later series. This library requires no special root access privileges, and can be easily adapted into applications by developers. The API is packaged in d2xx.jar and is distributed with demo application source code see technical note 147 (TN_147), which is available for download.
This PCN details the update of the FT311D Android Host IC from Rev B to Rev C. The device required a change to enable connection to the latest revision of Android Open Accessory Mode, upgraded from 1.0 to 2.0 in November 2012. All related product documentation has been updated to reflect this upgrade; we apologize for any inconvenience this may cause.
31st July 2012
The FT311D multi-interface Android host IC is launched today. Providing an instant bridge from your Android USB port(B) to peripheral hardware over GPIO, UART, PWM, I2C Master, SPI Slave or SPI Master interfaces.
Simply select the interface mode with pull up/pull down resistors on the FT311D mode select pins and plug into your Android (3.1 or later) device to access peripheral hardware over USB via Androids’ Open Accessory Mode. With this new chip, system providers can enhance connectivity to this popular mobile ecosystem, with the ability to create user applications that capitalize on Android platform resources; high-performance processing, accelerometers, touch-screen interfaces, etc.
Also included in the launch of the FT311D, are development modules and a suite of Android software examples allowing for rapid test and creation of new and exciting applications.

App Note: Accessing Android Open Accessory Mode with Vinco Development Platform
31st January 2012
This App Note describes connecting a Vinculum-II/ Vinco with the Vinco Touch-Key shield to a Motorola Xoom over USB running the Android Open Accessories Initiative environment.
Note : Many Android systems with
USB host capability enumerate devices with application
incompatible permissions (0660). In order to modify the default
permissions a user must have root access. FTDI does not accept any
responsibility for customers who choose to enable root access on
their Android platform and subsequently may void their warranty.
Enabling root access on such devices is entirely at the user’s own
