说明：  51单片机的eeprom和iic通信软件模拟程序(Eeprom and IIc communications in 51 single chip machines)

智能追踪小车，并且可以用遥控手动控制转弯加前后左右(Intelligent tracking car, and can be controlled manually with the remote turn around Canada)

说明：  将设备数字量的数据采集到MCU芯片中，以既定的mqtt格式由wifi模块连接路由器传输到服务器平台。(The data of device digital quantity is collected into MCU chip and transmitted to server platform by WiFi module connecting router in established mqtt format.)

一个完整的基于ST单片机的恒压频比变频控制程序，很有参考价值，附带的文档有详细的软件结构说明(A complete ST-based single-chip constant voltage frequency VF control program with a detailed description.)

CD4051/CC4051是单8通道数字控制模拟电子开关，有三个二进控制输入端A、B、C和INH输入，具有低导通阻抗和很低的截止漏电流。(CD4051/CC4051 is single channel 8 digital controlled analog electronic switch, there are three binary control input A, B, C and INH input, has low conduction resistance and very low by leakage current.)

说明：  通过读出SD卡中320x240像素、16位BMP图片的HEX数据，依次写到屏上，还原图片(Read SD card in 320x240 pixels, 16 BMP picture HEX data, in turn written to the screen to restore the picture)

包含proteus仿真文件及c语言程序，在开发板上进行过运行。利用双色LED显示电路，和四位静态数码管显示电路模拟十字路口交通信号灯。4位LED数码管显示时间，双色LED灯显示红绿灯状态。熟悉交通信号灯控制逻辑。设计一个十字路口的交通灯控制电路，要求南北方向和东西方向两个交叉路口的车辆交替运行。每次绿灯变红灯时,要求黄灯先亮3S,才能变换运行车辆。东西方向、南北方向车道除了有红、黄、绿灯指示外，每一种灯亮的时间都用数码管显示器进行显示（采用倒计时的方法）。考虑到特殊车辆情况，设置紧急转换开头。(It contains proteus simulation file and C language program. It has been run on the development board. Two-color LED display circuit and four-bit static digital tube display circuit are used to simulate traffic lights at intersections. Four-bit LED digital tube display time, two-color LED lights show the status of traffic lights. Familiar with traffic signal control logic. Design a traffic light control circuit at the intersection, which requires the vehicles running alternately in the north-south direction and the East-West direction. Every time the green light turns red, the yellow light is required to turn on 3S before changing the running vehicle. In addition to the red, yellow and green lights in the east-west and North-South lanes, the time of each kind of light is displayed by digital tube display (countdown method). Considering the special vehicle situation, set up the emergency switch start.)

通过一个简单例子，说明C语言对于学习单片机的重要性，有助于新手的入门.(By a simple example to illustrate the C language for learning the importance of SCM to help novice entry.)
