对ad7685的详细运用。加上12864显示。有电路图、芯片资料(Detailed use of ad7685 plus 12864 shows)

51单片机对串行存储器 24c02的 读写程序 (Serial memory 24c02 literacy procedures)

中文51单片机数据手册，包括89和90系列，初学者使用(Chinese 51 singlechip Data Handbook)

STM32控制24位ADC实现模数转换功能，并利用OLED显示。(STM32 controls the 24 bit ADC to realize the analog-to-digital conversion function and displays it by OLED.)

说明：  本程序是用单片机开发的DL/T645-2007的程序，本程序的开发已经在实际使用，能够读取电表的基本数据，返回的数据也是正常的。(This program is a DL / t645-2007 program developed by single chip microcomputer. The development of this program has been used in practice. It can read the basic data of electricity meter and return the normal data.)

51单片机中断与定时器INT，有设计原理图，结构图，以及程序源代码(51 MCU interrupt and timer INT, a design schematics, charts, and source code)

该程序实现4~20mA直流电流的采集，并通过485通信上传，通信协议为modbus rtu(4~20mA DC current measure)

本程序是关于LED在单片机里的流水等的演示程序，已经经过测试(This program is on the LED in the SCM in the water and other presentation program, has been tested)
