摘　　要：本文介绍了基于PIC16F774单片机开发的液晶显示系统的设计与实现,包括系统的硬件电路设计和软件实现。本系统采用图形点阵式的JM240128A液晶显示器,其驱动控制系统由内置T6963C控制器控制,该液晶显示器系统通用性强,是构成微机控制系统中显示模块的理想方案。LCD显示模块与PIC之间的接口技术采用数据串行发送方式,可以使硬件电路更加简化、紧凑和可靠,用途广泛。The paper introduces the design and realization of liquid crystal display system based on PIC16F774 single chip processor consisting of the hardware interface circuits design and software realization. The graphics lattice pattern JM240128A is adopted into the LCD display module. The LCD with T6963C as its controller can be widely used in industry and is a ideal choice for Micropro-cessor control systems. The serial interface technique is used between the LCD block and PIC single chip processor, which makes the connection scheme easy and brief.
