蜂鸣器在单片机上的应用,汇编语言,附原理图及说明学习文档 蜂鸣器的正极性的一端联接到5V电源上面，另一端联接到三极管的集电极，三极管的基级由单片机的P2.4管脚通过一个与非门来控制， 用户可以通过程序控制P2.4管脚的置低和置高来使蜂鸣器发出声音和关闭。 蜂鸣器的声音大小及音调可以通过调整P2.4管脚的置高时间及输出的波形进行控制，这一点可以在调试程序的时候来试验。-On the buzzer in single-chip applications, assembly language, with a schematic diagram and instructions to study documents the positive polarity of the end of the buzzer connected to the 5V power supply above, the other end connected to the transistor" s collector, the base level by the single-chip transistor Machine P2.4 pin through a NAND gate to control, the user can be programmed to set pin P2.4 low and set high to make the buzzer sound on and off. Buzzer sound size and pitch can be set by adjusting the P2.4 pin of the high time and output waveform control, and this point could be the time to test the debugger.

MCD1实战一,点亮一个LED并持续3秒后熄灭 该实战的目的作为学习和应用MCD1在线调试工具套件，进行项目的软件和硬件 联合调试的范例程序，也就是当做一个用户程序实例，而演示板暂时充当用户电 路的角色。这样就构成了一个软件、硬件齐全的自制项目模拟环境。 本程序实现的功能是，把端口RC的8条引脚全部设置为输出模式，并从RC0输出高电平 从而点亮RC0口的一个LED,持续3秒后LED熄灭. 该程序可用于PIC16F87X(A)所有系列-MCD1 real one, to light a LED and continuously put out 3 seconds after the real purpose for learning and application debugging MCD1 online suite of tools to carry out the project software and hardware examples of joint commissioning procedures, that is, as a user instance, and the demonstration user circuit board to serve as a temporary role. This constitutes a software, hardware, a full range of home-made simulation environment projects. Realize the function of this procedure is that the 8-port RC pin all set to output mode and high output from the RC0 so I RC0 a lit LED, continuous 3 seconds after the LED goes out. The program can be used to PIC16F87X ( A) All Series

C语言是一种计算机程序设计语言,它既具有高级语言的特点,又具有汇编语言的特点。它的功能性非常强大,目前是各高校的一门必修课。并且市场上许多软件也是基于C语言的平台而产生的,所以C语言在大学中的教学也称得上是"不遗余力"。但是近些年很多的学生普遍反映C语言晦涩难懂,不容易学透,非常努力的学最后却得不能心满意足,课程过后一无所获,甚至一个小小的程序都写不出来,于是针对这些情况就做出一些初步的分析,并且从C语言编程技巧上提出相关的改善对策。 (C language is a computer programming language, both with advanced language features, but also has characteristics of assembly language. Its function is very powerful, is now a required course in colleges and universities. And also a lot of software on the market based on the C language, platform and produce, so C language teaching at the university is also described as a "spare no effort." But in recent years, a lot of students generally reflect the C language obscure, not easy to learn thoroughly, very hard to learn, but finally could not have satisfied the course after nothing, even a small program that can not write, so for these situations to to make some preliminary analysis, and from the C programming language skills relevant improvement measures put forward.)
