串口通信原理

串口通信基本概念

串口通信是指通过串行接口进行数据传输的通信方式,在串口通信中，数据以一位一位的形式依次传输，通常使用串行通信接口标准RS232进行数据传输。

串口通信参数

串口通信参数主要包括波特率、数据位、停止位、校验位等，波特率是指每秒传输的位数，数据位是指数据传输的位数，停止位是指数据传输结束后，用于表示传输结束的位，校验位用于检测数据传输过程中的错误。

获取串口权限

在Android 6.0（API级别23）及以上版本中，需要动态申请串口权限，在AndroidManifest.xml文件中添加以下权限：

<usespermission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <usespermission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <usespermission
