基于单基片机的微型打印机的设计

摘要

目前，电子领域正向着数字化、信息化、微型化发展。打印机作为数字输出设备之一也朝着多功能、高性能的方向发展。微型打印机是电子信息领域一种很重要的输出设备。

本文设计的主要目的是运用单片机来控制微型打印机来实现打印的目的。本设计基于荣达RD-E系列微型打印机，以单片机P80C51以核心元件，辅以必要的外围电路（包括实时时钟电路、温度传感器和液晶显示模块、按键、打印机），采用并行接口技术，同时通过液晶显示器显示打印的数字和文字信息。可以实现打印一段固定的文字和单个任意的数字，同时把打印的内容显示在液晶屏上。本文主要用温度传感器测量温度，再通过单片机控制热敏电阻打印机打印出小票，设计了时钟接口电路，打印机接口电路，温度传感器接口电路和液晶显示接口电路。再辅助软件设计来进行调试。

BASED 0N A SINGLE SUBSTRATE MACHINE

DESIGNED FOR MICRO PRINTER

ABSTRACT

At present, the electronics field is developing towards digitalization, information, miniaturation. Printer, as one of the digital output devices are also moving into the direction of multi-function, high performance. The micro printer.It is a kind of important electronic information field output device.

Design is the main purpose of this article is to use single-chip microcomputer to control the micro printer for printing purposes. This design based on RD - E series micro printer, P80C51 MCU core components, supplemented by the necessary peripheral circuit (including real time clock circuit, temperature sensor and LCD display module, keys, printer), USES the parallel interface technology, at the same time, through the LCD display to print Numbers and text messages. Can achieve print a fixed text and a single arbitrary Numbers, and at the same time to print the contents of the display on the LCD screen. Temperature is measured in this paper, with a temperature sensor, and controlled by single chip thermal resistor printer to print out receipts, designs the interface circuit, clock printer interface circuit and temperature sensor interface circuit and LCD interface circuit. Auxiliary software designed to debug.
