本档含详细的电路原理、源程序，AT89C51主控，利用车辆检测器不仅可开发电子警察，还可开发出如：自动显示泊车数的停车场，实时配时的路口信号机系统，自动车库，交通车流量计数器等。-The file containing detailed circuit principle, source, AT89C51 master the use of vehicle detector electronics can be developed not only the police, but also developed such as: automatically displays the number of parking spaces car park, with real-time signal at the junction system, automatic garage, traffic flow, such as counters.

小型加减乘除计数器-ASM程序，包含LINK.EXE,MASM.EXE.-small counter- ASM procedures, including LINK.EXE, MASM.EXE. Thank you

本源程序是实现军用卷图机通过输入页码来是卷图机卷至指定得页码的功能，其中实现了卷动中相应页码输入，向前卷动，向后卷动，返回上次操作等操作，但由于时间原因在红外接口部分没有做好接口-the source is military aircraft through the volumes imported map pages is to map volumes to the designated machine rolls in the pages of the function, which achieved a scrolling pages corresponding input, scrolling forward and backward scrolling, the last operation to operation, But because of the time because in the infrared part of interface do not interface. .

这是一个时钟程序，用VB编写的，本人是VB初学者，有问题的地方请大家多多原谅。也请各位高手们多多指教。-This is a clock program, prepared by the VB, I VB beginners, problem areas you will excuse me please. Hope you have a master exhibitions.

汇编程序案例6数据加密程序encode.rar-Assembler Case 6 data encryption procedures encode.rar

应用背景 程序可以根据让用户自定义输入生成随机点数量、设定X范围、设定Y范围、设定Z范围来自定义生成一系列随机点数量，并根据用户设定的周围搜索点数量来进行规则格网的插值，然后根据输入的等高线间距进行等高线的生成。 关键技术在图层显示上，可以显示DEM数据、随机点数据、等高线数据，并根据用户自定义的图层进行显示和叠加。程序可以修改等高距进行显示。

汇编语言实例 好的很！-assembly language is a good example!

单片机产生PWM波对电机进行调速 脉冲宽度调制(Pulse Width Modulation―PWM)是指将输出信号的基本周期固定，通过调整基本周期内工作周期的大小来控制输出功率-Single-chip PWM wave generated on the motor speed Pulse width modulation (Pulse Width Modulation-PWM) refers to the basic cycle of the output signal of a fixed basic cycle by adjusting the duty cycle to control the size of the output power

用汇编编写的密码锁，proteus仿真，程序，原理图全套，希望对需要的人有用-Compilation prepared by using locks, proteus simulation, procedures, a full set of schematic diagram, in the hope that those who need it useful
