时钟 用数码管显示时，分，秒 按键可以调节时间 使用汇编语言...

风扇电机，生产线上质量检测系统，检测电机1800V，900V的漏电流参数，电机堵转电流参数及各档位转速的电路参数-Fan Motor, production line quality inspection system to detect electrical 1800V, 900V the leakage current parameters, the electrical current parameters stall speed and stall the circuit parameters

8051核的DES源代码 使用C语言写的基于51核的DES原码，变量定义使用汇编。占用了130字节RAM，比我所见到的包括汇编编写的都要快。 -8051 nuclear DES use source code written in C language based on the 51 nuclear DES original code, the use of variable definition compilation. Occupy the 130 byte RAM, than I have seen in the preparation of the compilation must fast.

单片机的入门小程序，用它来来扫描键盘，并根据不同的按键方式，显示不同流水灯-Procedures for the entry of small single-chip, to use it to scan the keyboard and buttons according to different methods show different water lights

ad9951，dds资料，有用的朋友看看，希望对你有用！-ad9951, dds information useful to look at the Friend, I hope useful for you!

一个控制城市夜景霓虹灯的程序，带proteus仿真。喜欢的可以看看哦-City night lights a control procedure, with proteus simulation. Oh look at like

多功能小车仿真。L298驱动直流电机，有液晶LCD显示方向，速度。-Multi-function car simulation. L298-driven DC motor,there is the direction of liquid crystal LCD display,speed.

学习单片机的教程往往是流水灯、数码管、键盘等等。这些例程主要是熟悉单片机的端口性质，程序算法一般都比较简单。极少见结合单片机I/O端口，内部存储器以及运算技巧为一体的综合性练习。超简单单片机学习套材中的16X16汉字点阵模块提供了一个全新的学习平台。在一块只能显示一个汉字的点阵中，只利用Atmega48的内部资源实现几个汉字的移动，不但要清楚点阵的物理性能，知道如何送数据；还要了解单片机的可用资源，并通过编程利用内部存储器移动交换数据，确实是需要些技-Microcontroller tutorial to learn is often water lights, digital control, keyboard and so on. These routines are mainly familiar with the nature of microcontroller port, the program algorithm is generally relatively simple. Rare combination of microcontroller I/O ports, the internal memory and computing skills integrated exercises. Super-simple MCU learning materials in the 16X16 set of Chinese characters dot-matrix module provides a new learning platform. Can only display one character at a dot-matrix, only the use of internal resources to achieve Atmega48 few characters of the movement, not only to clear the physical properties of dot-matrix, to know how to send data also understand the MCU resources available, and programmed to exchange data using internal m

一个学生的信息包括姓名、班级、学号、成绩，其中成绩需要精确到1位小数。试编写程序实现以下功能：(1)   可以录入学生成绩（十进制形式）；(2)   可以按要求（如学号或成绩）进行排序显示；(3)   可以统计平均成绩；可以统计不及格、60~70、70~80、80~90、90~100各分数段的人数。

反汇编源代码fd-Disassemble the source code fd

该程序是判断某年是否是闰年，即输入任何一年份，若是闰年，则输出闰年，若不是，则输出不是闰年。
