基于CPLD的LCD控制器的设计

Design of LCD Controller Based on CPLD Chip

介绍了一种使用CPLD芯片设计LCD控制器的方法 .用一片CPLD芯片就完成了全部的译码、时序控制、显示控制等功能 ,这样CPU和LCD之间就可能直接用一个CPLD芯片连接了 ,无需再加入其它的接口器件 .对系统的硬件及软件都给出了较详细的说明 ,并用可编程逻辑器件MAX70 0

This paper introduces the method of designing LCD controller with CPLD chip.Realizing all needed function such as encoding,sequence control,display control and so on with only one CPLD chip,it can be used to connect CPU with LCD without any other devices.This paper also gives the hardware and software of this system in detail,and then realizes by using programmable logic device MAX7000S series.
