我对Arduino和
Java有一个很好的了解,我决定采取一个刺,试图用我的三星galaxy 10.1选项卡来控制我的Arduino ATMega.我已经使用SDK管理器安装了API 12,Eclipse的ADT插件,现在我按照
Installing the Arduino software and necessary libraries(Android Open Accessory Development Kit)的说明安装ADK板的固件.当我编译它给我两个错误：
demokit:146: error: ‘acc’ was not declared in this scope
demokit:249: error: ‘touch_robot’ was not declared in this scope
并说
‘AndroidAccessory’ does not name a type.
代码如下所示：

顺便说一句,我甚至试图复制我的arduino目录中的ADK_relsease_0512文件夹仍然没有工作.提前致谢！
解决方法
现在我用Arduino 1.0获得了成功,我想分享解决方案：
>我用的是CapSense04.zip库：
>我从arduino_bundle_ADK.zip更改了以下文件中的类型从void到size_t：
AndroidAccessory.cpp行280：size_t AndroidAccessory :: write(uint8_t b)
AndroidAccessory.h第71行：size_t write(uint8_t b);
Max_LCD.cpp行257：inline size_t Max_LCD :: write(uint8_t value)
Max_LCD.h行101：virtual size_t write(uint8_t);
我也改了发送来写和接收来读,在demokit.pde(你会发现它在adk_release_0512.zip)
Demokit.pde行377：Wire.write(reg_addr);行383：c = Wire.read();第391行：Wire.write(reg_addr);第392行：Wire.write(val);
