Embedded Artists’ AOAA (Android Open Accessory Application) Kit (OM13036,598) is a standalone platform for evaluation and prototyping electronic accessories for Google’s Android operating system. It lets you get up-and-running with AOA experiments immediately. The AOAA board is also suitable for experimenting with CAN, Ethernet and RF networks.
The board has been developed by Embedded Artists in close cooperation with NXP. It contains two microcontrollers from NXP, the LPC1769 (Cortex-M3 core) and LPC11C24 (Cortex-M0 core). The two microcontrollers are connected via an on-board CAN network.
Android Open Accessory allows connecting Accessories to an Android device. The Accessory and Android device communicates over USB. The Accessory has to implement a USB Host interface, while the Android acts as a USB client (also called USB Device). The AOAA Kit supports the requirements to implement an Android Accessory and much more!
From a software perspective, the Accessory must implement a USB Host interface. There must also be two applications, one on the Accessory and one on the Android device. The two applications communicate over a custom defined protocol. AOA leaves this protocol open.
The applications have complete freedom in defining the protocol between them and to create functionality that supports the application in the best way.
Key Applications: eMetering, Lighting, Industrial networking, Alarm systems, White goods, Motor control, Elevator systems, Industrial and sensor based networks.
