SG12864液晶模块与单片机接口及图像显示设计实现

介绍了基于KS0108控制器的SG12864液晶模块的读写时序和指令系统,并设计了一种与AT89C52单片机的简洁接口,讨论了液晶模块图像显示的原理。针对该接口电路,给出了设计过程与编程方法,实现了液晶模块与单片机接口并进行图像显示。通过该设计,只需改变图像模值即可实现任意静态图像的显示,为液晶模块与单片机的接口设计以及实现图像显示提供了好的思路。

To Implement the Interface and Graphics Display between SG12864 LCD Module and Single-chip Microcomputer

This article introduces the read-write sequence and the instruction system of the SG12864 module, which based on KS0108 controller, then about the concise interface between SG12864 and the AT 89C52. In accordance with the interface circuit, provides the design process and programming method, which implements the graphics display between LCD module and single-chip microcomputer. According to the design, only change the graphic matrix value, the circuit can display arbitrarily static graphic, which provide idea for the display of static graphic and the interface design of LCD and single-chip microcomputer.
