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。 The hardware and software design method of Nios II LCD interface module based on SOPC is introduced. The interface of LCD module is realized by SOPCBuilder ’s component editor. The interface module can be used independently in the later development like interface module , So that developers do not have to understand the principle of LCD screen can be used to develop. The system uses standard C language functions to manipulate components to display information such as characters, graphics and colors, and is easy to use, flexible, efficient and low-cost.
