The system can display in both Chinese and English characters of the show and from top to bottom and move around the magic show. And can be cascaded to expand the screen size to achieve increased content purposes. The PC sends control mands and displays code to microcontroller, AT89S51 receives control mands from PC and shows the code, Driver module drives a 1616resolution LED lattice LED?s panel display scan showed. Communication between PC and the microcontroller using RS232C munications standards. the characteristics that AT89S51 microcontroller is cheap and could be coded conveniently makes the whole system Convenient to Maintenance and Repair. In addition, the system will take up only a small amount of the MCU I/O and memory,so that the system has functional space for expansion. Key words: AT89S51, lattice LED?s panel display, serial munication 本科生畢業(yè)論文 super vision in lar ge and m edium goods vehicle.
