C8051F120 UART complete program, its compilation, and test

此为组态王软件的单片机协议，假如我们想使用自己的模块，就要按照此协议来做下位机的通讯程序，经过我多年的使用，这样是事半功倍，介绍给大家。-This is Singlechip Kingview software agreement, if we are to use their own modules, it is necessary to do under this agreement in accordance with the digital machine communication procedures, after my many years of use, this is a multiplier, introduced to the U.S..

使用的同步串行三线SPI 接口，可以方便的连接采用SPI 通信协议的外围或另一片AVR 单片机，实现在 短距离内的高速同步通信。ATmega128 的SPI 采用硬件方式实现面向字节的全双工3 线同步通信，支持主 机、从机和2 种不同极性的SPI 时序，通信速率有7 种选择，主机方式的最高速率为1/2 系统时钟，从机方式 最高速率为1/4 系统时钟。-Use three-wire SPI synchronous serial interface, can be used to facilitate the connection of the external SPI communication protocol or another chip AVR microcontroller, realize in the short distance high-speed synchronous communication. ATmega128
