Temperature data display design based on AT89C51 microcontroller-EEWORLD

Collect

1. System Overview

The modules used in the system include AT89C51 microcontroller + LCD12864 + DS18B20 temperature detection module.

The system uses AT89C51 as the control core, uses the DS18B20 temperature detection module, and uses LCD12864 to display the collected temperature data. Compared with LCD1602, LCD12864 can display text. The LCD12864 display is called a dot matrix liquid crystal display module, also known as 12864, because it It is an array of 64 arrays in 128 rows including 12864 LCD dots. Each display point should have a binary number, 0 means gone, 1 means bright. If a dictionary is set up in the module, there is no need to design Chinese characters.

2. Simulation Overview

1. The ambient temperature is displayed on the LCD12864 display.

2. Press to display date and time data after interface switching.

3. Programming

Use Keil 51 for programming. When you open Proteus, the program is burned by default. If it is not burned, click on the AT89C51 microcontroller and import the program to run the system (the program file is a file with the suffix hex).
