摘 要

在日常生活中,由于信息来源的技术特点不同,信息获取的方法也多种多样,但是,通过感觉器官获取信息存在很大的局限性,很多信息是五官难以在快节奏的生活中捕捉的。因此,智能终端的出现给人们的生活带来了很大的便利。

在智能终端方面,目前市面上已经成熟的终端机也有不同的方案。由于设计者考虑到智能终端的使用场合及人群,各种智能终端开发时基于的开发平台也会有很大区别。这里主要介绍的是通过MSP430F235单片机控制液晶显示打印的智能终端,它的主要原理是根据MSP430F235单片机,RD-W32热敏打印机模块和240128点阵液晶显示模块组成这个智能终端的三大核心板块,主控板MSP430单片机对热敏打印机和液晶显示进行控制,实现操作。

本文主要介绍的核心部分采用MSP430F235对信息进行处理,对液晶显示屏、打印机等外围设备进行控制。MSP430F235单片机是一个低功耗的单片机,特别适合于电池应用的场合或手持设备。 液晶模块采用内藏 T6963C 的液晶显示器,优势在于:已经实现了T6963C 与行、列驱动器及显示缓冲区RAM 的接口。打印模块采用RD-W32系列打印机,支持全切,半切功能,打印纸宽为57mm;整台打印机只由一块控制板,一个带切刀的打印头组成。

Abstract

In daily life, because the technical characteristics is different from the sources of information, diverse methods of information acquisition, however, access to information through the sense organs, a lot of limitations, a lot of information is difficult to capture in the fast-paced of life. Therefore, the intelligent terminal bring a big convenience to people’s lives.

The intelligent terminals, the current market mature terminals have different options. As the designers consider the use of intelligent terminals and crowd situations, the development platform will be very different when development of a variety of intelligent terminals based on. This introduction is through the MSP430F235 MCU LCD printing intelligent terminal, its main principle is based on MSP430F235 MCU, RD-W32 thermal printer module and 240x128dot matrix liquid crystal display, which make up of intelligent terminal modules of three core sections. The MSP430 MCU on the thermal printer and LCD control, to achieve operation.

This article focuses on the core of information processing using MSP430F235 on the LCD screen, printer and other peripherals to control. MSP430F235 MCU is a low-power microcontrollers are ideally suited for battery applications or handheld device. LCD module containing the chip T6963C. Advantage: already implement the T6963C and the rows, columns, drive and display buffer RAM interface. Print module using RD-W32 series printer, support full, half cut functionality, 57mm paper width; the entire printer only by a dashboard, a print head with cutter.

Key words: MSP430F235; T6963C; LCD; RD-W32 thermal printer
