Nios Ⅱ液晶屏接口组件设计

Design of Nios Ⅱ LCD Interface Component

介绍基于SOPC的Nios II液晶屏接口组件的硬件和软件设计方法,利用SOPCBuilder的组件编辑器实现液晶屏接口设计,该接口组件可以和系统自带的接口组件一样,在以后的开发中独立地使用,让开发者不必了解液晶屏原理就可以使用液晶屏进行开发。系统以标准C语言函数来操作组件,可以显示字符、图形和颜色等信息,使用方便,具有灵活性、高效性和低成本的特点。

Both hardware and software method to design the Niosll interface for LCD based on SOPC was introduced. Component editor in SOPC Builder is used to design the interface component for LCD. Applications developers can use this interface component independently as same as system provided in- terface component without knowing LCD principle. System access hardware with standard C language functions and can display character, image, color information and so on. It has the features of agility, high efficiency and low cost.
