This paper introduces a kind of simple 16×32 LED display screen design process based on MCS-51 single chip minicomputer. MCS-51 Controls 6 driver 74HC595 through this chip actuates the display monitor demonstration. Show dynamic show that makes static graphic or text can be achieved, shifted out of various formats. The detail hardware scheme, software flow and C language programmer design and so on is followed. 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.
Keywords: Lattice display screen, MCS-51 MCU, LED, C language
