摘要
介绍了处理器与液晶显示模块之间硬件接口的一种设计方案。采用I／O方式连接，实现了SEP3203与液晶显示控制器JM12864G的一种接口设计方法．并通过与键盘复用接口，节省了处理器硬件引脚资源。给出了主要部分软件实现的流程，并在实际系统中得到验证。
Introduce a hardware interface design between CPU and LCD controller. The design implements an interface between SEP3203 and JM12864G.useing an I/O request signal. By interface sharing, retrench the hardware resource of the CPU pins. The main part of the software flowchart is proposed and the design was validated in practical system application.
