摘要
首先介绍了控制器TMS320LF2407的主要特点及液晶显示控制器SED1335的原理与使用,然后给出了液晶显示系统的硬件接口设计方案,给出了具体的软件实现方法,最终实现了DSP系统的液晶多层界面显示的设计,并在实际应用中取得了很好的效果。
Firstly the paper presents the main features of TMS320LF2407 and the principle and usage of SED1335 controller,then gives the design of the interface of the DSP and the SED1335 controller,some software of this system also been given in the paper. Finally the multilayer menu of LCD has been realized and achieves good effect.
