FT311D and FT312D Demo_APK_User_Guide Application Note

PublishTime：2024-07-25

●FTDI’s FT311D device is targeted at providing a data bridge from an Android USB device port through a USB2.0 Full-Speed Host to alternative interfaces such as GPIO, UART, PWM, I²C or SPI, while the FT312D device is specific to UART interfaces. To enable complete functionality, the development of JAVA applications to run on Android platforms is required. This user guide provides sample applications that have been developed by FTDI Chip as design examples.
●Android is a commonly used operating system, mostly applied in portable devices such as mobile phones and tablet computing devices. Sometimes it is desirable to connect these devices to external peripherals (“accessories” in Android terminology). One possible solution is to use USB technology to provide the necessary connectivity. To enable this digital link, the FT311D and FT312D integrated circuits from FTDI Chip will enumerate the USB device port of an Android device per the Android Open Accessory Mode Specification (Android version 3.1 onwards). This application note outlines how to run demonstration applications that FTDI Chip has provided. Although source code is provided, it is not discussed in this application note and is provided as is; functionality is neither guaranteed nor supported.
