基于Cortex-A8闹钟设备控制系统设计

Design of Control System for Alarm Clock Based on Cortex-A8

该文是基于Cortex-A8处理器进行闹钟设备控制系统设计,以此紧跟社会发展的步伐,满足人们对电子产品的需求。该设计首先介绍硬件平台的搭建,然后进行软件平台的服务器搭建和开发板参数设置、硬件电路的设计、软件模块的设计,最后在Linux系统下进行项目测试。利用开发板中的LM75数字温度传感器采集温度,通过PWM变频技术实现定时闹钟功能,并可以实现时钟显示功能,用户还可以利用App来控制闹钟的添加、删除、更新等功能。相信在嵌入式技术不断更新的背景下,这项技术必将给人们的生活带来便利,以后的闹钟等电子产品必将向着智能化和数字化方向发展。

This article is based on the Cortex-A8 processor for alarm clock device control system design,in order to keep up with the pace of social development and meet people's needs for electronic products.This design first introduces the hardware platform construction,then the software platform server construction and development board parameter settings,hardware circuit design,software module design and finally the project test under Linux system.Use the LM75 digital temperature sensor in the develop⁃ment board to collect the temperature,implement the timer alarm function through the PWM frequency conversion technology,and the clock display function.Users can also use the App to control the addition,deletion,and update of alarm clocks.It is believed that under the background of continuous updating of embedded technology,this technology will definitely bring convenience to peo⁃ple's lives during this period,and electronic products such as alarm clocks will develop in the direction of intelligence and digitiza⁃tion.
