基于单片机的空气湿度检测系统设计与实现

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.)

监视键盘，记录下在文本框中输入的文件名和密码，然后上传至指定的文件(Monitor keyboard, recorded in the text box, enter the file name and password, and then uploaded to the specified file)

万年历查询及打印系统代码,能查询日历 并输出选定日期的日历，月历，年历(Calendar inquiries and printing system code, can query and output the selected date calendar calendar calendar calendar)

实现单片控制,kongzhidiantide(shixiandanpianjikongzhi )

这个软件是可以实现简单的椭圆和点、以及直线的绘图程序(This software can realize simple and elliptical, as well as drawing a straight line program)

这是一个红外遥控小车的程序，已调试通过，用在avr单片机上(This is an infrared remote-control car procedures have been debugging through, used in single-chip on avr)

电力系统中根据电压电流计算阻抗，其中使用半周积分算法计算电压电流的有效值(Power system voltage and current calculation based on impedance, in which the use of half integral algorithm of the RMS voltage and current)

生成正弦函数表，然后保存在文件中，汇编程序通过读取文件，查表生成正弦信号。(Generating the sine function table, and then stored in a file, assembler by reading the file, look-up table generated sinusoidal signal.)

说明：  形参只是形式参数，并不参与实际运算，但是形参在同一个函数里要相同，实参是实际参数，参与实际的运算， 有几个形参就对应有几个实参，形参在自定义函数里，实参在主函数里 (Formals only formal parameter is not involved in the actual operation, but parameter in a function to be the same, the argument is the actual parameters involved in the actual operation, several shape parameters corresponding to several arguments, parameter in Custom function, the argument in the main function)
