1.引入依赖

implementation project(path: ':ecg500')

2.申请使用权限（https://developer.android.com/guide/topics/connectivity/usb/host?hl=zh-cn）

<manifest ...>
  <uses-feature android:name="android.hardware.usb.host" /> <!-- usb权限 -->
  <uses-sdk android:minSdkVersion="12" />
  ...
  <application>
      <!-- 适配7.0 -->
       <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths" />
        </provider>
   
      <activity ...>
         ...
           <!-- usb连接 -->
          <intent-filter>
              <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
          </intent-filter>
   
          <meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
           android:resource="@xml/device_filter" />
      </activity>
   </application>
   </manifest>
  

<?xml version="1.0" encoding="utf-8"?>

<resources>
   <usb-device vendor-id="6790" product-id="29987" /> <!-- FT230X 新设备-->
   <usb-device vendor-id="1027" product-id="24597" /> <!-- FT230X 旧设备-->
</resources>

3.设备通信流程提示，详例参见demo

1. 连接

   usbConnManager.connectFunction()
   

2. 获取数据

   usbConnManager.collectReadData()
   

4.生成Hl7Xml文件上传获取心电报告

具体参见GetPDFViewModel

1. https://github.com/viatom-develop/Lepu-AI/blob/main/AI%E5%BC%80%E6%94%BE%E5%B9%B3%E5%8F%B0%E6%8E%A5%E5%8F%A3.md
2. 通过开通账号密码获取接口请求令牌，具体请参考示例及接口文档

5.切换波形展示

MainEcgManager.getInstance().updateMainEcgShowStyle(LeadType.LEAD_6)

6.本地心电传统分析

具体参见：viewViewModel.getValue().getLocalPdf(ecgDataArray)
结论：viewViewModel.getValue().getMLocalResult().observe()
全部分析数据：viewViewModel.getValue().getMLocalResultBean().observe()
