摘要

介绍了DSP芯片TMS320F2812和液晶模块MGLS-12032的功能特点以及TMS320F2812与液晶模块之间的接口设计方法

通过适当的电路设计解决了电平不兼容的问题。通过分析液晶模块的时序

阐述了在TMS320F2812中用软件模拟时序的方法

也即通过软件的方法解决了高速DSP处理器与慢速液晶模块之间时序不兼容的问题

实现了对液晶模块MGLS-12032的控制。

Abstract

TMS320F2812 digital signal processor and MGLS-12032 LCD module are introduced. The interface circuit between the digital signal processor and the LCD module is discussed. By designing a proper interface circuit between the DSP controller and the LCD module

the problem of electrical level compatibility is settled. According to the timing chart of the LCD module

this paper shows how to design LCD display program to control the LCD module properly. By this way the compatibility problem between a high speed device and a low speed one is solved well.
