摘　　要：介绍TMS320LF2407型DSP的主要特点和LCM320240液晶显示模块的基本使用方法。在此基础上讨论了DSP与液晶显示屏之间采用数字I/O口模拟时序的硬件接口设计方案,给出了基于C语言具体的实现方法,最终实现了DSP与LCM320240的良好接口,并在实际系统应用中取得了成功。同时,可为其他DSP与LCD的接口设计和控制实现提供参考。The main features of TMS320LF2407 DSP and the basic method of application of LCM320240 LCD are presented.The hardware interface design scheme about using digital I/O ports to simulate time sequence between DSP and LCD is discussed,and the specific software implementation method using C language is given.A good interface between DSP and LCM320240 is ultimately realizes and it proves to be successful in the practical system application.At the same time,it can be a references to design and control of interface between other DSP and LCD.
