AVR单片机与VRAM型彩色液晶模块接口电路及驱动程序设计

Design of Interface Circuit and Driving Program for AVR and VRAM Color LCD Module

以AVR单片机为控制核心,以LR035VRAM彩色液晶模块为人机界面,介绍ATmega1280单片机与VRAM型彩色液晶模块接口之间的设计方法。通过分析液晶模块的时序,阐述了在ATmega1280单片机中用软件模拟时序的方法,给出了基于ICCAVR编程语言的驱动程序设计模块,实现了对液晶模块LR035VRAM的显示控制。同时,将其成功移植应用在某火炮仿真瞄准训练显示系统中。

Used the single chip microcomputer of AVR as controller,LR035VRAM color LCD module as human machine interface,the interface circuit between ATmega1280 and VRAM color LCD module was introduced.According to the timing chart of LCD module,the module of driving program design was provided based on ICCAVR programmed language and the display control of LR035VRAM color LCD module was realized.It was successfully transplanted in the display system of gun aimed simulation training.
