摘要
分析了目前显示市场上各种主流显示器件的特性,介绍了OLED显示模块以及S3C2440的结构。针对OLED显示模块中8位数据并行接口占用I/O管脚较多,接口设计繁琐,无法满足系统需求的情况,采用SPI总线接口,进行相应的软件、硬件设计,达到了系统节约接口的要求。在占用资源较少的情况下实现了OLED屏幕的正常显示。
The characteristics of main display devices in the current market is analyzed.And this paper chooses the OLED display module,based on the general requirements of the S3C2440-based-system and the advantages and disadvantages of the display devices above.By analyzing the structure of S3C2440,this work uses SPI bus interface to solve the problem that the 8-bit parallel interface take too many I/O pins.Through the design of the hardware and software,the design meets the demand of the system saving interfaces,and achieving the OLED screen display module application on the condition.
