Design and Application of Intelligent LED Information Display Screen
摘要
Abstract
In regard to the issues including information can not be update off-line, the splash screen which was caused by conflict between reading-writing frame cache and scanning, an intelligent LED display control system design method was presented based on ATMEGA32. In hardware section, MBI5026 was used to enhance the driver ability, and ADXL202 was used to build up the abilities of gravity recognition and automatic information display rotation. In software section, Chinese input-PINYIN, real time information display was available in the program, a scanning optimal model is also established. By setting up the parameters of numbers of row-column and numbers of scanning optimally, the scanning speed can be improved to its maximum capacity. Experimental results show that the system has great advantages, including the brightness can be adjusted intelligently, the external circuit is simple and easy to install and upgrade. In short, it is an excellent application for engineering.关键词
