基于128×64点阵液晶显示的智能温度控制器的设计与实现

Design and implementation of the intelligent temperature controller based on 128×64 dot matrix liquid crystal display

以智能温度控制器的设计实验为依托,文章给出了一套液晶显示模块驱动实验的设计方案,详细介绍了LM3033液晶显示模块的功能特性、接口电路及应用程序。实验中应用DS18B20温度传感器实现温度信号的采集,并把采集到的信号传送给单片机,单片机将信号进行处理完成相应的智能控制,同时将环境温度、系统状态等信息显示在LM3033液晶显示模块上。

Based on the intelligent temperature controller design experiment, a design scheme of the liquid crystal display module （LCM） driving experiment is given in this paper. The functional properties, the interface circuit, and the application program of the LM3033 LCM are introduced in detail. In this experiment, the temperature signal is collected through the DS18B20 digital temperature sensor, and then transmitted to the MCU. The temperature signal processing and the intelligent control are performed by MCU. At the same time, informations, such as ambient temperature and system status are displayed on the LM3033 LCM.
