WS:I2S声道选择线,I2S协议可以传输左右两个声道的数据,WS信号是由主机发送给从机的,从机根据WS的电平高低,判断当前数据帧发送左声道还是右声道数据,WS低电平时,从机发送左声道数据,高电平发送右声道。 L/R:芯片左右声道选择线,每个麦克风只能检测一处声源,因此若要进行双声道录音,就要使用两个模块,一左一右放置。

RS232/RS422/RS485通信接口区别RS-232、RS-422与RS-485标准只对接口的电气特性做出规定,而不涉及接插件、电缆或协议,在此基础上用户可以建立自己的高层通信协议。例如:视频服务器都带有多个RS422串行通讯接口,每个接口均可通过RS422通讯线由外部计算机控制实现记录与播放。
