本例程基于STM32F103RC系列ARM单片机的外部按键测试程序(This routine is based on external key test program of STM32F103RC series ARM microcontroller)

说明：  由于超声波指向性强，能量消耗缓慢，在介质中传播的距离较远，因而超声波经常用于距离的测量，如测距仪和物位测量仪等都可以通过超声波来实现。利用超声波检测往往比较迅速、方便、计算简单、易于做到实时控制，并且在测量精度方面能达到工业实用的要求，因此在移动机器人研制上也得到了广泛的应用。(Because of its strong directivity, slow energy consumption and long propagation distance in the medium, ultrasound is often used for distance measurement, such as range finder and level gauge, which can be achieved by ultrasound. Ultrasound detection is often fast, convenient, simple in calculation, easy to achieve real-time control, and can meet the requirements of industrial application in measurement accuracy, so it has been widely used in the development of mobile robots.)
