摘要
本文采用以ST7920为控制器的YM12864R构成了自动监控型独立通气笼盒(Individually Ventilated Cages,IVC)系统的人机界面显示部分;给出了点阵液晶显示模块与单片机之间的硬件接口设计;介绍了液晶模块文本显示和绘图显示的基本特性及实现,并重点介绍了任意字符反白和任意位置任意大小图形显示的方法。
The human-machine interface display of individually ventilated cages（IVC） with automatic monitoring is realized based on YM12864R which takes ST7920 as controller.The design of hardware interface between ST7920 and MCU is introduced.The paper shows the basic characteristics and implementation of data display and graphic display of the LCM,especially the display of any highlighted character or graphics of different sizes at any position.
