基于NiosⅡ处理器的128*64液晶显示接口的实现

Implementation of 128*64 display interface module based on processor NiosⅡ

通过对基于SOPC技术的嵌入式NiosⅡ处理器系统的介绍,在分析液晶驱动芯片时序的基础上,利用硬件描述语言,针对128*64液晶显示模块,编写逻辑接口,给出了自定义逻辑的实现方法及在NiosⅡIDE集成开发环境下的基本编程应用,实现了128*64液晶在嵌入式NiosⅡ处理器系统的应用.

This paper introduces the system of the embedded processor NiosⅡ based on SOPC technology.For the 128＊64 LCD module interface,we use HDL to finish logic interface on the basis of the timing analysis,give the method of custom logic and basic programming applications in NiosⅡ IDE,and achieve the application of the 128＊64 LCD in the system of embedded processor NiosⅡ.
