摘要
介绍了内置ST7920控制器的点阵图形液晶显示模块FYD12864-0204B的特点及使用原理,并设计了利用TMS320F2812的双向数字I/O口实现对该液晶的间接显示控制。同时,文中还给出了FYD12864-0402B同F2812的简单接口电路,以及相关的接口程序设计。
This paper presented the characteristics and application for the dot-matrix graphics LCD which is inner ST7920 controller And designed has used the bidirectional digital I/O mouth of TMS320F2812 realization to this liquid crystal indirect display control At the same time, this paper has also produced the simple connection electric circuit, as well as correlation interface routine design.
