Abstract: A lattice LED’s panel display system controlled by a microcomputer DS80C320 was given. The system received the control command and display data from PC by way of one serial interface of DS80C320 using RS-232/RS-485 communication protocol. The microcomputer controls the scanning of data display by way of another serial interface of DS80C320. It used a new kind of high-capacity FLASH storage 29F040 as its data storage ware . The main points of system design were also presented .
