android - 为什么 ADK 的 demokit 程序不能在 Arduino 中编译？

Question

我对 Arduino 和 Java 有很好的了解，因此我决定尝试使用 Samsung Galaxy 10.1 选项卡来控制我的 Arduino ATMega。我已经安装了带有 SDK 管理器的 API 12、Eclipse 的 ADT 插件，现在我正在按照安装 Arduino 软件和必要的库（在Android Open Accessory Development Kit中）中的说明安装 ADK 板的固件。当我点击编译时，它给了我两个错误：

demokit:146: 错误: 'acc' 未在此范围内声明

demokit：249：错误：“touch_robot”未在此范围内声明

并说

'AndroidAccessory' 没有命名类型。

代码如下所示：

现在我用 Arduino 1.0 取得了成功，我想分享解决方案：

我使用了CapSense04.zip库：
我在arduino_bundle_ADK.zip的以下文件中将类型从 void 更改为 size_t ：

AndroidAccessory.cpp 第 280 行：size_t AndroidAccessory::write(uint8_t b)
AndroidAccessory.h 第 71 行：size_t write(uint8_t b);

Max_LCD.cpp 第 257 行：inline size_t Max_LCD::write(uint8_t value)
Max_LCD.h 第 101 行：virtual size_t write(uint8_t);

我还在demokit.pde 中将send更改为write并将receive更改为read（您可以在 adk_release_0512.zip 中找到它）

Demokit.pde 第 377Wire.write(reg_addr);
行：第 383c = Wire.read();
行：第 391Wire.write(reg_addr);
行：第 392 行：Wire.write(val);

也许尝试使用早期版本的 Arduino（即不是 arduino 1.0）——据我所知，最近的更新更改了一些类名。

我遇到了这里详述的错误，所以这为我修复了它：http ://www.jjoe64.com/2011/12/adk-arduino-wprogramh-not-found.html

Arduino 1.0 IDE中没有WProgram.h。包含语句应该是：

#if ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#endif

这将修复 Arduino 1.0 下的 header not found 问题。

代码的更高版本（arduino_bundle_ADK_02）不需要修补。

免责声明：除了 ADK 应用程序弹出之外，我仍然无法让这个动物园与 Nexus S 一起工作（在初始连接几秒钟后害怕“设置数据包错误：D”），但我认为原因在其他地方。

考虑到该类现在在 CapSense 库 v.04 中被命名为 (CapacitiveSensor) 并且该库现在也称为 CapacitiveSensor 然后在按下验证后，我已经将错误“CapSense”更改为“CapacitiveSensor”属性“touch_robot.capSense”到“touch_robot.capacitiveSensor”

只是为了分享信息，如果您使用 arduino uno (Mega328)，请查看此站点。uno 的固件在这里。注意它使用 arduino IDE v0.22 并且需要添加库。

快乐的微控制器编程...

最好的问候，

ADK 软件最近刚刚更新为与 Arduino 1.0 兼容。

查看 developer.android.com 上的 ADK 页面：http: //developer.android.com/guide/topics/usb/adk.html

新的下载链接是： https ://dl-ssl.google.com/android/adk/adk_release_20120606.zip
