无刷直流电机的SPWM程序,可以用来实现变频的作用

本程序实现驱动TC1320实现DA转换。 入口参数：待转换的数据在SOU中。 出口参数：无。-TC1320 drive the process to achieve the realization of DA conversion. Entrance parameters: the data to be converted in the SOU. Export parameters: None.

基于51单片机的带时间显示和紧急控制的交通灯的设计。 此程序在硬件上调试通，用定时器1延时，外部中断0接紧急控制，R0为100MS延时常数，R2为状态延时常数，8279控制数码管显示时间,用P1口控制双色灯-With 51 single-chip based on the time display and the emergency control of traffic lights design. On this process in hardware debugging pass, with one delay timer, external interrupt 0 then the emergency control, R0 for 100MS constant delay, R2 for a state of constant delay, digital 8279 control display time control using two-color lights I P1

开始时，显示“00”，第1次按下SP1后就开始计时。 第2次按SP1后，计时停止。 第3次按SP1后，计时归零。 -Beginning to show 00 , 1st press SP1 after the beginning of time. 2nd by SP1, the time to stop. The 3rd by SP1, the time zero.

s3c44b0初始化的引导程序，包括系统初始化，定义堆栈，进入主程序。-S3C44B0 guidance initialization procedures, including system initialization, the definition of the stack into the main program.

《汇编语言》(Assembly Language)是计算机专业中一门重要的基础课程，是一种面向机器的低级语言。它依赖于硬件，能通过巧妙的程序设计充分发挥硬件的潜力。汇编语言程序产生的代码运行效率高。因此，到目前为止，许多软件系统(例如操作系统等)的核心部分仍然用汇编语言来编写。-err

这是我们实习的源代码，是我们老师提供的，希望对大家有所帮助。呵呵，你们认为呢？-This is our attachment to the source code, is provided by the teachers, we hope to help. Oh, do you think?

按键显示汇编，设计语言教科书和编译教科书的有关知识，并增加了一些有关汇编 层体系结构的材料，以满足没学过计算机组织的学生们的需要-Button shows a compilation of language textbooks and textbooks compiled the relevant knowledge, and an increase of some of the compilation of the material layer architecture to meet the needs of organizations never learned the computer needs of students

RS232中断通信-RS232 communication disruption

An example to illustrate how to set the internal adjustable CID gain and receive FSK or DTMF data. Assume end-code of DTMF data string is "D".-An example to illustrate how to set the inte CID rnal adjustable gain and receive FSK or DTMF data. Assume end-of DTMF code data string is "D" .

本动画先显示一些提示信息，然后按任意键进入，只见一个方框向中间由大变小，并留下痕迹，然后出现一个心，按空格重复出现心，按其他键将重复,按Q键退出程序，。-the animation first showing some hints information, and then by arbitrary keys to enter, I saw a box to the middle into small, and leave your mark, and then there appears a heart by heart spaces repeated by other keys to repeat, according to withdraw from the Q key procedures.
