IDO-SBC3566基于瑞芯微RK3566研发的一款高性能低功耗的智能主板采用四核A55,主频高达1.8GHz专为个人移动互联网设备和AIOT设备而设计内置了多种功能强大的嵌入式硬件引擎为高端应用提供了优异的性能支持几乎全格式的4K编解码内置3DGPU能够完全兼容OpenGL ES1.1/2.0/3.2、OpenCL2.0和Vulkan1.0.特殊的MMU2D硬件引擎此外凭借其强大的兼容性可以轻松地转换基于TensorFlow/MXNet/PyTorch/Caffe等一系列框架的网络模型。
支持AndroidLinuxOpenHarmony麒麟OS等多种操作系统可广泛应用于平板、教育平板、带屏音箱、词典笔、云终端、视频会议系统等安卓/Linux类应用方案以及其他带屏消费类、或轻量级AI应用场景。
产品规格书查看深圳触觉智能官网-产品中心 添加以太网共享服务
在源码目录下新建以太网共享服务文件实现系统开机启动时开启以太网共享。
packages/apps/Settings/src/com/android/settings/StartEth1ShareRunnable.java
文件内容如下
package com.android.settings;//以太网共享
import android.app.Service;
import android.content.Context;
import android.os.Handler;
import android.util.Log;
import android.content.Intent;
import android.os.IBinder;import android.net.ConnectivityManager;
import static android.net.TetheringManager.TETHERING_ETHERNET;
import android.net.ConnectivityManager.OnStartTetheringCallback;public class StartEth1ShareRunnable extends Service {private static final String TAG StartEth1ShareRunnable;private Context mContext;//以太网共享private ConnectivityManager mCm;private OnStartTetheringCallback mStartTetheringCallback;Overridepublic IBinder onBind(Intent arg0) {// TODO Auto-generated method stubreturn null;}Overridepublic void onCreate() {super.onCreate();mCm (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);mStartTetheringCallback new OnStartTetheringCallback();mHandler.post(StartEth1ShareRunnable);//启用以太网}private Handler mHandler new Handler();private class OnStartTetheringCallback extends ConnectivityManager.OnStartTetheringCallback {Overridepublic void onTetheringStarted() {Log.d(TAG, ethernet onTetheringStarted!\n);}Overridepublic void onTetheringFailed() {Log.e(TAG, ethernet onTetheringFailed!\n);}}//以太网共享private Runnable StartEth1ShareRunnable new Runnable() {Overridepublic void run() {try {if (mCm ! null)mCm.startTethering(TETHERING_ETHERNET, true, mStartTetheringCallback, mHandler);//开启以太网共享} catch (Exception e) {Log.e(TAG, ethernet startTethering error!\n);e.printStackTrace();mHandler.postDelayed(StartEth1ShareRunnable, 10000);//延迟10秒后重新执行}}};
}
在packages/apps/Settings/src/com/android/settings/ 添加一个广播 MyBootReceiver.java 用于接收启动完成事件在收到广播后调用StartEth1ShareRunnable服务
package com.android.settings;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;public class MyBootReceiver extends BroadcastReceiver {Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString action intent.getAction();if (action.equals(Intent.ACTION_BOOT_COMPLETED)){Intent service new Intent(context, StartEth1ShareRunnable.class);context.startService(service);}}
}
功能验证 SBC3566主板插入可使用的EC20 4G模块以及SIM卡如下图所示 从SBC3566主板网口接一根网线到另外一块主板网口上并给两个主板供电。
在SBC3566系统查看网口及4G获取的IP
共享的网口网络IP192.168.5.1 4G网卡IP10.47.102.124
