MGLS12032A点阵图形式液晶显示模块与8031单片机的接口设计

Interface design for dot matrix graphic mode LCD module MGLS12032A with 8031 singlechip microcomputer

ＭＧＬＳ１２０３２Ａ是香港精电公司生产的点阵图形式液晶显示器，非常适合于便携式应用，其读写时序采用的是６８系列ＭＰＵ的操作时序。正确分析时序是电路设计正确与否的关键，为了将其应用于８０系列ＭＰＵ，在详细分析了其时序后，提出了一种其与８０３１单片机的接口电路，并给出了用Ｃ语言编写的应用函数。本电路及软件已成功应用工程项目中。

MGLS12032A is a dot matrix graphic mode LCD device, it is extraordinary fit for portable application. Because its readwrite time sequence is same as that of 68 series MPU, we analyze its time sequence and then present a interface circuit with 8031 singlechip microcomputer in order to use it in 80 series MPU. Finally, we present its application functions that written with C language. This circuit and corresponding software have been applied in a project successfully.
