是protel的讲义，应该有利于大家的学习

在单片机上实现对工业现场的多模态PID控制源代码,方面大家参考-In SCM to achieve the industrial scene, multi-mode PID control of source code, refer to aspects of U.S.

基于STC12C5412AD单片机的简易存储示波器设计-STC12C5412AD based on the simple single-chip design storage oscilloscope

本程序功能是利用单片机控制用户板上的小键盘，将按下的键通过单片机的串口发送给PC机，在PC机串口助手显示出来。用行翻转法的方法来识别输入的键盘。 二、通过单片机将键盘按下的键在LCD上显示出来。 -This procedure is the use of single-chip control functions of the user on-board a small keyboard, the keys will be pressed through the single-chip serial port sent to the PC, the PC Serial Port assistants displayed. Line inversion method used to identify the method of keyboard input. Second, through the single-chip microcomputer keyboard keys pressed on the LCD display.

lcd液晶屏显示的源程序,c语言编写.在KEIL环境下编译,直接下载到单片机即可-lcd LCD display source, c language. in KEIL compiler environment, can be directly downloaded to a single-chip microcomputer

24位高精度AD：AD7710的中文资料-24 high-accuracy AD: AD7710 Chinese information

C语言控制单片机。里面包含了很多用C语言编写的经典的例子，对初学者入门及提高很有帮助。-C language to control single-chip microcomputer. Which contains a lot of use of C language classic example of entry for beginners and helpful to improve.

我认为很经典的供初学者学习的数码管显示程序-I think that is very classic for beginners to learn the digital tube display program

自己写的C51仿真器代码-himself wrote the code C51 Emulator

：章介绍了数据采集系统中STC12系列单片机与PC机之间的串行通信。设计了sTc12c2052AD 与 MAX232的硬件电路，使用汇编语言编程，设置了串行1：7的工作方式，相应的波特率计算方法及特点，发送并接 收数据。单片机从EEPROM 中读取数据，通过R．S-232将其传入PC，并将数据存储在24C02中。-: Chapter introduces data acquisition system STC12 Series MCU and PC serial communication between machines. Designed sTc12c2052AD with MAX232 hardware circuit, the use of assembly language programming, set up the way the work of serial 1:7, the corresponding baud rate calculation method and the characteristics of sending and receiving data. Single-chip EEPROM read data from, by R. S-232 to incoming PC, and data storage in the 24C02.
