摘要
本文研制一种基于51单片机实时控制的LCD液晶显示屏控制系统。硬件系统由单片机最小系统和液晶显示系统组成,PC机进行显示内容的编辑和字模数据的提取;液晶显示系统由主控模块T6963C和LCD液晶显示模块接口电路组成,主控模块负责接收单片机字模数据并控制各显示模块工作,显示模块以T6963C主控制器为核心,控制LCD液晶显示屏显示,为了方便系统扩展,各模块之间的连接采用接插式结构,单片机与PC机之间采用RS232标准接口进行数据和命令的串行通信。本文不仅从总体上对系统进行了整体规划,还以其中一个实例详细介绍了PC机字模的提取、字模数据的发送、单片机串行接收数据、液晶显示屏的显示等部分的软硬件设计及实现过程。本系统的设计优点硬件电路简单,软件功能完善,控制系统可靠,性价比较高等特点,具有一定的使用和参考价值。Abstract
This article designs with develops one kind based on 51 SCM(Single Chip Microcomputer ) the real-time control LCD display monitor control system. This system is composed by on SCM small system and LCD display system, on the PC machine carries on the demonstration content the edition and matrix data withdrawing; LCD display system controls the module and certain LCD by the host demonstrated the module T6963C composes, the host controls the module T6963C to be responsible for in the receive the SCM matrix data and controls each demonstration module work, demonstrated the module take the host controls the module T6963C as a core, controls the LCD display monitor display, In order to the convenient system expands, between various modules connection uses meets inserts the type structure, between the SCM and PC machine to use the RS-232 standard to carry on the data and the order serial communication. This article not only has carried on the whole plan from the overall to the system, but also in detail introduced take module design as the example the PC machine matrix withdraws, the matrix data transmission, the monolithic integrated circuit serial receive data, the LCD display monitor display and so on the partial software and hardware design and the realiz
