USART2

C8051芯片的I2C总线控制程序，包含五段代码（读写EEPROM,主控读写单字节，多字节，被动读写单字节，多字节）(C8051 chip of I2C bus control procedures, including five sections code (reading and writing EEPROM, master literacy single-byte, many bytes, passive literacy single-byte, multibyte) )

本程序是关于串口通信，已经调试通过，希望对大家有所帮助。(RS485)

说明：  餐饮信息管理系统源代码，主要用于餐饮内容信息的数据管理。(The source code of the catering information management system is mainly used for data management of catering content information.)

说明：  单片机串口通信的应用，通过串口，我们的个人电脑和单片机系统进行通信。 个人电脑作为上位机，向下位机单片机系统发送十六进制或者ASCLL码，单片机 系统接收后，用LED显示接收到的数据和向上位机发回原样数据。(The application of SCM serial communication, through the serial port, our personal computer and SCM system to communicate. As the upper computer, the personal computer sends the hexadecimal or ascll code to the lower computer single chip microcomputer system After receiving, the system uses led to display the received data and send back the original data to the upper computer.)

一个用于调试串口调试的工具，可以查看所有的串口，方便开发串口编程(A debugger for debugging serial ports, you can view all the serial ports, to facilitate the development of serial programming)

一个很通用的51的串口通信程序，很好用，但仅供参考(A very universal serial port communication program 51, very good, but for reference only)

一个用Visual C++编写的串口通信的例程，实现了一些串口属性的设置。(A use of Visual C++, prepared by serial communication routines to achieve a number of serial port property settings.)
