Android Open Accessory Application Kit

Produktbeschreibung

Embedded Artists’ AOAA Kit 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.

Easy usage

Download code to the board by using:

• ISP over UART program download. Use the free tool Flash Magic to download a compiled application to the LPC1769 side of the AOAA board. Please note that this tool cannot be used to download code to the LPC11C24 side of the board.
• Use the free LPCXpresso IDE together with, for example, an LPC-Link. It is possible to create an LPC-Link given an LPCXpresso Board or you can use the LPC-Link enhanced LPC1227 board where no modification is needed and a 10-pos IDC ribbon cable is included.
• Use a debugger and JTAG adapter of your choice which supports the Cortex-M3 and Cortex-M0 ARM cores and more specifically the NXP LPC1769 and LPC11C24 microcontrollers. You might need an adapter such as the 10-pin to 20-pin JTAG Adpater Kit between your JTAG solution and the target board.

The following resources are available for download either directly below or from our support site after registration of the AOAA Kit.
The right column contains the different sample applications that will help you get up-and-running quickly with your application program development.

Software

Sample Software Disclaimer

Project files exist for Code Red's LPCXpresso/Red Suite.

• Demo 1: Android Open Accessory demo which lets you control and monitor the AOA Board (LPC1769 side) from an Android device.
• Demo 2: Android Open Accessory demo which lets an Android device detect CAN nodes (such as the LPC11C24 side of the AOA board) in a CAN network. The CAN nodes can be controlled and monitored from the Android device.
• Demo 3: Android Open Accessory demo which lets an Android device detect Xbee nodes in an Xbee network. The Xbee nodes can be controlled and monitored from the Android device.
• FreeRTOS has been ported to the board and a demo is available that show how to use it. 
• lwIP v1.4.0 has been ported to the board. The httpserver_raw (webserver) application from the lwIP contrib package is available with a small modification to use the on-board SD-card interface instead of the ROM based file system.
• FatFs file system module has been ported to the board. The lwIP demo (based on httpserver_raw) is using this module to access files on an SD card.
• nxpUSBlib is available and used in the AOA demos.

• XBee Node code for the LPC1769 LPCXpresso Board together with an LPCXpresso Base Board. Demo 3 is illustrating the use of a XBee network where this code, on the above mentioned hardware, can act as one of the XBee nodes.

XBee Node on LPC1769 LPCXpresso with Base Board

One of the AOA demos is controlling XBee nodes in an XBee network. This bundle contains an implementation of an XBee node that runs on an LPC1769 LPCXpresso Board (EA-XPR-003) togheter with an LPCXpresso Base Board (EA-XPR-021)
