【Abstract】 This paper introduces a design project of controlled system in which Chinese characters information is dynamically displayed with 8×8 LED lattice, and provides concrete realization methad of each part’s of functional electric circuit. From which we can understand the basic principle of the LED lattice displaying Chinese characters. This system makes the choice of displaying information and implementation by PLD. It is very convenient and practical to extend and modify information.更多还原
