基于MSP430的智能仪表的LCD驱动设计

Design of LCD Drive for Intelligent Instrument Based on MSP430

介绍了基于MSP430单片机的智能仪表的微功耗中英文人机界面的设计思路和方法,并给出了重要的程序。通过MSP430F147与字符型LCD(液晶显示器)接口电路,实现了中文人机界面的设计方案。详细介绍了以MSP430F147为核心进行液晶显示驱动的实现方法,给出了软硬件设计的相关内容。同时,对MSP430F147超低功耗控制的关键问题进行论述,低功耗特性的基本要求贯穿于中文人机界面的设计始终。

This paper introduces the Design of Driving LCD of Intelligent Instrument Based on MSP430 series single-chip controller, and gives the example procedure at the same time. Man-machine interface play an important role in the embedded systems which use single-chip controller as its core. With the use of LCD inter- face circuit, the Chinese and English display interface has been realized. The LCD system drive method based on MSP430 is introduced in details and the related content about the software and hardware devise are presen- ted. In addition, some key issues on MSP430 ultra-low-power control are discussed. Ultra-low-power characteristic through out the Chinese Man-machine interface design usually is its basic requirement.
