Design Based on MCU Chinese Character
Dot Array Display System
Abstract:For ordinary plane static advertisement screen cannot dynamic display and LCD screen video advertisement costs too high, this paper put forward the LED dot array display system design method. This system uses AT89C51 MCU as the core, Chinese characters shows the use of LED dot array display, temperature detection circuit using DS18B20 temperature sensor, the time display circuit uses the clock chip DS1302, and through the auxiliary circuit to achieve any set time. The system realizes the Chinese characters dot array display of scrolling text, image display as well as clock and temperature display.
Key words: MCU; LED dot Array; Dynamic display
