本文利用NiosⅡ软核设计LCD和矩阵键盘接口,以中断代替查询完成对矩阵键盘的控制;设计点阵型LCD与NiosⅡ的接口,实现对LCD中英文显示的支持。矩阵键盘控制和LCD接口均做成自定义外设组件,可重用、便于移植,体现了SOPC技术设计的优势。
The interfaces of LCD and Matrix_Key_Board are designed Based on NiosII soft core, the key control method of inquiry is replaced by interrupt, and the LCD is designed to support the Chinese and English display.
