Abstract
The LED lattice display system is a kind of new information display media with the rapid development of the computer, micro-electronics, photoelectron technology.
This 16*64 LED display system includes SPCE061A MCU system, sixteen 8*8 LED lattice modules, display driving circuit, SPR4096 memory module, PCF8563 as the real-time clock chip, keyboard controller et. In addition, it includes LCD circuit, real-time temperature detective, RF communication circuit. This system can display the numbers, letters, Chinese characters. It can display the information timely and circularly, up-rollingly, down rollingly left-rollingly, right-rollingly. The lightness of the displaying information can be adjusted continuously. Further more, this system can be remote controlled and communicate with PC by COM1 to update the display information.
