51单片机控制智能温控风扇，多档调节，pwd调速。包含源码和电路图(51 single chip computer control intelligent temperature control fan, multi-stage adjustment, PWD speed regulation. Contains source code and circuit diagrams)

基于单片机的智能家居系统：红外遥控，红外报警 ，光与LED灯，串口显示光信息 ，时间显示，电机正转，，电机反转，温度报警 (Microcontroller-based Smart Home System: Infrared remote control, infrared alarm, light and LED lights, serial optical information display, time display, the motor is transferred, motor reversal, temperature alarm)

绪论，介绍了温度控制的发展趋势，发展现状，以及PID控制的相关介绍(the introduction of an article)

基于C51单片机proteus仿真的音乐播放器，可以播放多首歌曲以及基本的播放器按键功能。(C51 MCU proteus simulation based music player that can play multiple songs, and basic player key functions.)

C8051F060初始化程序，包括端口看门狗定时器串口晶振(C8051F060 initialization procedures, including serial port Watchdog Timer oscillator)

说明：  ADS112C04驱动，可采集电压，产生恒定电流等(ADS112C04 Driver,can Acquisition voltage,and Generating a constant current)

蓝桥杯CT107D矩阵键盘的源代码测试使用供学习和参考(Blue Bridge Cup Matrix Keyboard)

单片机和matlab串口通信程序，简单易用(Microcontroller and matlab serial communication program, easy to use)

在51开发板上，向AT24C02 EEPROM中写入0x(xx),同时读出之后赋值给P1口。注意三处加*********(In the 51 development board， write 0x (xx)to AT24C02 EEPROM , while after reading assigned to P1 port. Note that three plus。)

说明：  sd卡初始，由于SD卡使用SPI模式，并且是块读取(512Byte),所以需要单片机提供大于512的可用RAM，以供缓冲使用 这里可以选择STC89c52RD+、STC89C58RD+、STC89C516RD+，后缀RD+表明扩展RAM是1024字节，RC表明扩展RAM256字节(sd card original, because the SD card using SPI mode, and is a block read (512Byte), so they need the microcontroller to provide more than 512 of the available RAM, for buffer used here can choose STC89c52RD+, STC89C58RD+, STC89C516RD+, the suffix RD+ that extended RAM is 1024 bytes, RC that extended RAM256 byte)
