基于DSP的LCD显示控制系统的设计与实现

Design and Implementation of DSP-based LCD Display Control System

基于TEDSPC5409Ⅲ型DSP实验系统和CCS2.0软件,采用DSP与单片机相结合的方式控制LCD,设计并实现了LCD显示控制系统。系统中的DSP实现与单片机之间的并口通讯,单片机将DSP送来的数据进行实时处理,并将数理所对应的汉字进行循环显示,使系统具有循环显示中文汉字和字符的功能。系统的DSP可以一次发送多个数据,单片机控制液晶显示屏循环显示两行汉字。系统具有较高的实用价值。

Based on TEDSPC5409Ⅲ DSP experimental system and CCS2.0 software,control of LCD by combining DSP and MCU,the LCD display control system.In which DSP and MCU communicate between the parallel port is designed.MCU will process the data sent by DSP in real time and display the Chinese characters corresponding to the data.The system has the function of the recycling display for Chinese characters and characters.The DSP system can send multiple data a time and MCU control LCD screen shows two lines of Chinese characters circularly.
