And single tablets machine since with of serial features can achieved its and other peripherals MCU or PC machine Zhijian of munications, such on makes control system more of convenient practical, uses single tablets machine of serial munications can achieved data of remote transmission, and data analysis and system integrated control features, especially in data volume than larger of occasions Xia, uses a hosts to all from machine sent control instruction is a is good of address programme, in this process in the, serial munications is achieved single tablets machine and single tablets machine Zhijian munications of key. This article introduced the design of serial munication based on singlechip puter by pressing the input data, singlechip serial data to another microcontroller, while sending data are available at the 2 on a singlechip puter controlled digital tube display, accuracy to detect serial munication. Described in this method is simple and easy to understand, can be widely applied to various serial data munication systems.
