内藏液晶显示控制器T6963C与DSP的接口应用

The Application Interface of LCD Display Module Based on Inner T6963C Controller and DSP

点阵式液晶显示模块具有性能稳定、适合应用于便携式智能仪器仪表等特点,是一种较低价位、具有较高显示功能的显示器件。文中介绍了内藏液晶显示控制器T6963C的液晶显示模块的特点及其显示方式。在此基础上,给出了该液晶显示模块与基于DSP(数字信号处理器)TMS320LF2407A的嵌入式系统的硬件接口电路和部分C语言代码。最后,实现了该液晶显示模块在TMS320LF2407A的嵌入式系统中的液晶显示功能,成为该现场温度监控系统的重要组成部分。其程序与硬件逻辑图也可为其他DSP系统提供参考。

The main feature of dot-matrix liquid crystal display module has stable performance and it has been applied to portable intelligent instrument. It has a low cost and is a display device which has very strong display function. This article introduces feature and display way of embedded system based on T6963. Based on this, this paper introduces hardware interface circuit and part C language code of LCD display module and embedded system based on TMS320LF2407A. The LCD display function is realized and this module becomes the most part in temperature control system. The hardware and software can help of other DSP systems.
