汇编语言是很多相关课程(如数据结构、操作系统、微机原理等)的重要基础。其实仅从课程关系的角度讨论汇编语言的重要性未免片面，概括地说，如果你想从事计算机科学方面的工作的话，汇编语言的基础是必不可缺的。原因很简单，我们的工作平台、研究对象都是机器，汇编语言是人和计算机沟通的最直接的方式，它描述了机器最终所要执行的指令序列。想深入研究英国文化，不会英语行吗？汇编语言是和具体的微处理器相联系的，每一种微处理器的汇编语言都不一样，只能通过一种常用的、结构简洁的微处理器的汇编语言来进行学习，从而达到学习汇编的两个最根本的目的：充分获得底层编程的体验，深刻理解机器运行程序的机理。这两个目的达到了，其他目的也就自然而然地达到了。举例来说，你在学习操作系统等课程时，对许多问题就会有很通透的理解。 学习不能在一台抽象的计算机上来进行，必须针对一台具体的计算机来

面对一个人的大型C/C++程序时，只看其对struct 的使用情况我们就可以对其编写者的编程经验进行评估。因为一个大型的C/C++程序，势必要涉及一些(甚至大量)进行数据组合的结构体，这些结构体可以将原本意义属于一个整体的数据组合在一起。从某种程度上来说，会不会用struct，怎样用struct 是区别一个开发人员是否具备丰富开发经历的标志。
In the face of a large-scale C / C + + program, we can evaluate the programming experience of its author only by looking at its use of struct. Because a large-scale C / C + + program is bound to involve some (or even a large number) structures for data combination, which can combine the data originally belonging to a whole. To some extent, will you use struct? How to use struct is a sign to distinguish whether a developer has rich development experience. (2020-03-16, C/C++, 3967KB, 下载0次)

超声波传感器工作原理：
①采用I/O触发测距，给至少10us的高电平信号；
②模块自动发送8个40kHZ的方波，自动检测是否有信号返回；
③有信号返回，通过I/O输出一高电平，高电平持续的时间就是超声波从发射到返回的时间。
测试距离=(高电平时间*声速(340M/S))/2。
Ultrasonic sensor working principle:
(1) trigger the ranging with I/O to give at least 10us high level signal.
Module automatically sends 8 40kHZ Fang Bo to automatically detect whether there is a signal return.
(3) a signal is returned, and a high level is output through I/O. The duration of high level is the time from ultrasonic emission to return.
Test distance = (high level time * sound speed (340M/S)) /2. (2018-05-01, C/C++, 1196KB, 下载4次)
