摘要
液晶显示器(LCD)由于体积小、功耗低、寿命长、无电磁辐射等优点,在各类智能设备和仪器仪表中得到了广泛的应用。本文介绍了图形点阵式液晶控制器MG2401281与MCS51系列单片机8031的硬件接口电路,详细阐述了软件的编程方法。给出了液晶显示模块在半自动生化分析仪中应用的实例。从现场运行情况来看,该仪器显示清晰、直观、信息量大,大大地方便了操作。
Liquid Crystal Display(LCD)has many merits,such as small bulk,long life, no electromagnetic radiation and it consumes low power,it has been widely used in many intelligent equipments and instruments.The hardware interface circuit between graphic dot matrix liquid crystal controller MG-240128-1and MCS-51 series single chip computer 8031 is introduced,the software design is also clarified emphatically.A practical example of the application of liquid crystal module in photometer is given.From the operation condition,it is shown that this instrument has advantages such as displaying in focus,visual,more information and operating more conveniently than ever.
