51单片机的RS232串口程序，可以编译通过-RS232_MCU_CAN COMPLIE SUCEESS

本程序是基于51系列单片实现UART通讯的程序，调试编译已通过，可以直接使用，可以实现rs232通信功能。适合初学者-This program is based on 51 series single-chip implementation of a UART communication program, debug compiler has passed, it can be used directly, you can achieve rs232 communication. Suitabl

用51单片控制电压检测，包括ad转换，数据存储处理，通讯程序等功能。反复使用，程序可靠。-use MCU51 systems to control test circuit,include ad,eeprom,rs232,etc.

51+sht75+lcd+rs232,本人的毕业设计，经测试具备准确的温湿度测量，且具有超调报警功能-51+sht75+lcd+rs232,it is my graduate project, this program has an accuracy measurement of humity and temperature, and has an alarm function.

用PC机与多个51单片机通过RS232进行通讯。在多机通讯中，要保证主机与所选择的从机实现可靠的通信，必须保证串口具有识别的功能。在串行口控制寄存器SCON中 有一位叫做SM2，就是为了多机通讯而设置的控制位-Using a PC and a number of 51 single-chip RS232 communication. In multi-machine communication, to ensure that the host and the selected slave t
