一.超声波图片

测量距离：2cm——400cm
在这里插入图片描述

二.时序图

(1).以下时序图要先提供一个至少10us的脉冲触发信号，告诉单片机我准备好了，然后该超声波模块内部将发出8个40Khz的的周期电平并检测回波，这时候是超声波模块发送的波，检测能不能发送超声波，与单片机无关，所以代码就不用写写这里的代码，然后一旦检测到有回波信号后则向单片机输出回响信号，高电平持续的时间就是超声波发出波到返回的时间。

(2).以超声波为主体，Trig是接受触发信号RX，Echo是发送超声波TX。

六.换算距离

从下图手册可知，我们距离s可以等于时间微妙us/58，单位是cm，所以把定时器设置成1ms，在然后在定时器中断里面设置一个标志位，进去一次就是1ms，然后标志位在乘于一个1000，就是把1ms换算成1000us了，然后这个是来回的时间，但是要注意超声波回来的最后一刻，定时器没有达到ARR自动重装值的话，就结束了，这个也要算进去时间，就是TIM_GetCounter，然后t得到之后，t需要/2，因为是来回的时间，然后因为声速是340m/s，需要把us换成s，就是t * 0.00001/2=t/2000000，然后340m/s需要换成cm，也就是340 * 100，所以s=t/2000000 * 340 * 100，最后换算就是t/58。
