摘要
阐述了OCMJ8X15B图形液晶显示器的引脚功能、控制指令,并以脱扣器寿命测试仪为例,介绍了图形液晶显示器与单片机的接口技术,给出了硬件电路。C8051F020单片机的接口驱动程序采用C51编程,提供了一个液晶显示器的写命令和数据操作子程序,并已调试通过。所设计的C8051F系列单片机与液晶显示器的接口硬件和软件实现简单,可直接应用于其他设备中。
The pin functions and control instructions of the graphic liquid crystal display（LCD） module OCMJ8X15B were described.The interface technique of the graphic LCD and single-chip microcomputer（SCM） for the release lifetime tester was introduced,and the corresponding hardware circuit was presented.The interface driver program of C8051F020 was developed in C51.A written command and a debugged data operating subprogram of LCD were also provided.The designed circuit and program of C8051F series SCM and LCD interface could be directly applied to other equipment.
