摘　　要：本文介绍了一种基于AT89S52单片机控制的旋转式LED显示牌的设计,该显示牌以少量的LED在底座电机的旋转下,配合单片机的显示控制,可以在一个柱面顺序显示广告内容,具有耗费低,占用空间小,可视角度大,维护方便等优点,具有较高的经济价值。This paper introduces a kind of design of rotary LED board which bases on AT89S52 microcontroller. This display board needs a smalI amount of LEDs,when the motor installed in the base drives the rotation of the stem, and this apparatus can sequentially display advertising content in a cylinder in conditions of single chip microcomputer display control. This apparatus has many merits, such as low consumption, small space occupation, large viewing - angle and easy maintenance. It has rather high economic value.
