使用三星单片机S3F9454编写的1LED流水灯(Samsung SCM S3F9454 prepared using light water 1LED)

main.c已详尽注释连接的引脚 和 调试助手参数。STM32分别以串口,硬件SPI,模拟并口驱动CH395,4个socket连接, 原路返回上位机发送的数据。串口模式支持更改工作波特率，硬件SPI速率最高36MHz, 模拟并口较快，这三种模式支持在stm32任意型号下。(Main.c has commented on pins and debugging assistant parameters in detail. STM32 drives CH395 and 4 sockets by serial port, hardware SPI and analog parallel port respectively, and returns the data sent by the host computer in the original way. Serial mode supports changing working baud rate. Hardware SPI rate is up to 36MHz and analog parallel port is fast. These three modes support any model of stm32.)

这是基于STC89C52编程开发的脉搏检测器，里面包含PCB原理图，程序代码和一篇参考论文。(This is based programming development STC89C52 pulse detector, which contains PCB schematics, program code and a reference papers.)

说明：  MODBUS通讯协议及编程，对理解MODBUS很有帮助(MODBUS communication protocol and programming are very helpful for understanding MODBUS.)

可实验0.5KHZ到10KHZ的简单测频,并由数码管显示出来!(Experimental 0.5KHZ can be simple to 10KHz frequency measurement by digital tube display!)

51单片机实现简易家电定时控制装置，主要是完成家电的定时工作，防止出现烧点家电的作用(51 single-chip implementation simple timing control device for household appliances, major home appliances are to complete the job from time to time to prevent burning at the role of home appliances)

十字路口车辆穿梭，行人熙攘，车行车道，人行人道，有条不紊。那么靠什么来实现这井然秩序呢？靠的是交通信号灯的自动指挥系统。交通信号灯控制方式很多。本设计主要分为五大模块输入控制电路、时钟控制电路、片内外程序切换控制、显示电路。以MSC-51系列单片机IntelAT89C51为中心器件来设计交通灯控制器，实现了AT89C51芯片的P0口设置红、绿灯、黄灯燃亮时间的功能；为了系统稳定可靠采用了74LS14施密特触发器芯片的消抖电路，避免了系统因输入信号抖动产生误操作；显示时间直接通过AT89C51的P2口输出，由CD4511驱动LED数码管显示红灯燃亮时间。(Crossroads shuttle vehicles, pedestrians bustling, car lanes, walkways, everything in good order and well arranged. So what can we do to achieve this orderly order? It depends on the automatic command system of traffic lights. There are many ways to control traffic lights. This design is mainly divided into five modules, input control circuit, clock control circuit, chip internal and external program switching control, display circuit. MSC-51 series microcontroller IntelAT89C51 centric devices to design the traffic light controller, the AT89C51 chip P0 port set of red, green, yellow light to kindle the function of time; the system is stable and reliable with shake eliminating circuit 74LS14 Schmidt trigger chip, avoids the system for input signal jitter generation misoperation; direct display time AT89C51 through the P2 port output, driven by CD4511 LED digital tube display lights burning time.)
