单片机课程设计定时闹钟[摘要] 单片机电子闹钟是集电子技术、数字显示技术为一体的产品,具有按时闹铃,使用方便等优点。本论文从电子闹钟系统的功能、软件设计、软件调试等方面论述这一系统。本设计使用学校提供的单片机试验箱为基础,以AT89C52RC芯片为核心,采用动态扫描方式显示,通过使用该单片机,加之在显示电路部分使用的驱动电路,实现在4个LED数码管上显示时间、定时、闹铃的功能,并通过4个按键实现设置日期、进行调时、设定闹铃等功能。在实现各功能时数码管进行相应显示,闹铃或定时时间到时蜂鸣器响,整点报时等功能。本课程设计主要的问题,在于如何编写与调试用C语言实现的单片机程序。在此,我通过不断地修改程序与仿真,让程序达到我期望的程度。[关键词]定时闹钟、C52单片机、软件分析、软件设计
Timing alarm of MCU Course Design[Abstract] The design uses microcontroller chamber to AT89C52RC chip as the core, the use of dynamic scanning display, through the use of the microcontroller, in addition to part of the circuit used in the display drive circuit, to achieve the 4 LED digital tube display time, time, alarm functions, and implementation through 4 keys to set the date, the tone, the alarm and other functions, all functions in the realization of the corresponding digital display, alarm or timer time when the buzzer sounds, The whole point timekeeping functions. I use the C language as the programming language, and by the relevant simulation software emulation, through hardware and software to achieve the ultimate goal.MCU-based alarm clock is a set of electronic technology, digital display technology for the integration of products, with time and alarm, ease of use. This paper from the electronic alarm system features, software design, software debugging, we discussed the system.[Key words] Clock, C52 Microcontroller, Software Analysis, Software Programming
