基于单片机的超声波测距仪的软件程序，控制产生发出超声波，利用接收探头接收到被反射回来的超声波来达到测距的目的。-Based on Ultrasonic range finder software program to control the generation emit ultrasonic probe is received by the receiving ultrasonic waves are reflected back to achieve ranging purposes.

用c语音编写的超声波测距的源代码，可以实现超声波测距的界面c语言编程-C speech prepared by ultrasonic distance of the source code, you can achieve ultrasonic distance c programming language interface
