Double Tap Parameter Configuration 无法通过内码设置

Question

我正在为双击事件编写代码，但它运行不正常，所以我认为配置以下内部寄存器可能有助于获得更好的结果：

1. doubleTapDur,
2. doubleTap安静，
3. 点击Ths，
4. 轴

   为了设置寄存器的值，我通过 Movesense showcase adb bridge app 使用了 ADB bridge。这是 APK 的链接：Showcaseapp-debug_adb-bridge-build.apk

   我使用下面的命令来读写双击参数。它正在工作。

   阅读：

   adb.exe shell am broadcast -a "android.intent.action.MOVESENSE"  --es type get --es path Component/LSM6DS3/TapParams --es value '''{}'''
   
   

   写：

    adb.exe shell am broadcast -a "android.intent.action.MOVESENSE"  --es type put --es path Component/LSM6DS3/TapParams --es value '''{\"newParams\":{\"doubleTapDur\": 8, \"doubleTapQuiet\": 3, \"tapThs\": 8, \"axes\": 8}}'''
   

   为了在内部（内部代码）设置这些参数，我编写了一个函数 DoubleTAPConfig()，它在 params 中设置值。但它不起作用。我不确定我错过了什么。任何帮助将不胜感激。

   这是我的代码：-

               DOUBLETAPEnabled = !DOUBLETAPEnabled;
           }

       }
   }
   
   void DOUBLETAP::DoubleTAPConfig()
   {
       WB_RES::TapParams TapConfig;
   
       TapConfig.doubleTapDur = 8;   // set 0-15   Default:_ 0000
       TapConfig.doubleTapQuiet = 3; // set 0-3    Default value:_ 00
       TapConfig.tapThs = 8;         // set 0-31    Default value:_ 00000
       TapConfig.axes = 8;           // set 0-14   bitfield:_ x=8, y=4, z=2
   
       asyncPut(WB_RES::LOCAL::COMPONENT_LSM6DS3_TAPPARAMS(), AsyncRequestOptions::Empty, TapConfig);
       
       // also try with this coomund line 
      // asyncPut(WB_RES::LOCAL::COMPONENT_LSM6DS3_WAKEUP(),AsyncRequestOptions(NULL, 0, true), TapConfig);
   
   }
   
   

   我不确定我错过了什么。任何帮助将不胜感激。

/Component/LSM6DS3/TapParams - 资源直接访问 LSM6 芯片寄存器，因此在您的固件代码中会发生以下情况：

1. 您将 tap-params 设置到寄存器中（DoubleTAPConfig 方法）
2. 您启动 DOUBLE_TAP 检测，这会立即将寄存器中的点击参数重置为默认值

   你需要：

   1. 先订阅DOUBLE_TAP服务
   2. 只有在它运行时（最安全的方法是等到您收到带有 resultCode == 200 的 onSubscribeResult 回调），调用 DoubleTAPConfig()。
