This design is a 16 ×32 lattice LED electron display monitor design. The whole equipment is with the 40-pin AT89C51 MCU (Micro Controller Unit) produced by the American ATMEL company at the core, introduced take it as the control system LED lattice electron display monitor dynamic design and the development process. Controls good 6 driver 74HC595 through this chip actuates the display monitor demonstration. The electronic screen can show all kinds of written or monochrome images, one full screen display Chinese characters, 8 pieces of 8×8 dot-matrix LED display modules to form the 16×32 dot matrix display mode. Show dynamic show that makes static graphic or text can be achieved, shifted out of various formats. This paper describes the hardware design of the LED dot matrix display, and the principle function of the various parts of the circuit, the corresponding software program design and the use of some such. MCM process control system used for editing C language, Programming control points indicated by the corresponding LED anode and overcast extreme level. We can effectively control the defense showed bright spots. The lattice data shows characters can prepare themselves (that is, direct lattice Painting), which can also be extracted from the standard font.
Key words: LED dispay Mnitor, AT89C51 Micro Controller Unit5, C language, Dynamic display.
