基于AVR单片机的VRAM型彩色液晶显示模块设计

Design of VRAM Color LCD Display Module Based on AVR

介绍一种基于AVR单片机和硬件汉字库的VRAM型彩色液晶显示模块的设计。给出彩色液晶显示器的显示原理、硬件接口设计框图以及硬件汉字库的制作和应用,同时给出基于C语言的程序设计模块,实现了应用VRAM型液晶的模块化,便于移植在其他类型的单片机。

The paper introduces a design of VRAM color LCD display module based on AVR and the chip with Chinese characters. It provides the principle of this kind of LCD, the hardware design diagram and the making method of chip with Chinese characters. It also provides the module of program design based on C programmed language, which gives a module for applying to the VRAM color LCD so that the LCD is convenient for transplanting to other microcontrollers.
