Description: 程序能用于24小时计时,能作为秒表使用,能定时闹铃1分钟(也可关).
使用方法:开机后在00:00:00起开始计时,(1)长按P1.0进入调分状态:分单元闪烁
按P1.0加1,按P1.1减1.再长按P1.0进入时调整状态,时单元闪烁,加减调整同调分.-Procedures can be used 24 hours a time, can use as a stopwatch, alarm 1 can regular minutes (can also be off). Usage: reboot after the starting time 00:00:00, (1) long to enter the transfer by P1.0 sub-state: sub-unit plus 1 flashing by P1.0, P1.1 reduced by one. P1.0 longer by the time of entry adjust status, flashes when the unit, adjust plus or minus points cohomology. Platform: |

Description: 本文设计实现的是一个多功能数字电子钟，其功能为：24小时制时、分、秒的时间显示，具有整点报时功能；年、月、日及星期的日历显示；具有秒表功能；可显示当前环境温度；可通过按键对各时间信息进行调整。系统采用单片机AT89C52作为主控芯片。系统中的显示模块采用LCD1602液晶显示器实现。LCD1602可以显示两行字符，每行16个字符，能够满足本系统的显示要求。系统中的温度采集模块采用DS18B20芯片实现。DS18B20体积小，其输出量是数字量，可直接与单片机通信，且为单总线传送，可简化电路，大大减小系统的体积。系统中的时钟产生模块采用DS1302时钟芯片实现。DS1302时钟芯片为单总线传送，只需一条线就可以完成与单片机之间数据的交换，且该芯片准确度很高，可大大减小电子钟的时间误差。总得来说本设计电路简单、容易实现且性能稳定。-This article is designed to achieve a multi-functional digital clock, and its function as follows: a 24-hour hour, minute, seconds display, with the whole point timekeeping function year, month, day and week s calendar display with a stopwatch function can shows the current ambient temperature through key information on the time to adjust. AT89C52 single-chip computer system as the master chip. System module used to achieve LCD1602 LCD Monitor. LCD1602 can display two lines of characters, 16 characters per line, to meet the requirements of the system display. The temperature acquisition system DS18B20 chip modules. DS18B20 small size, its output is digital, can be directly related to single-chip communications, and send a single bus, simplifies the circuit, greatly reducing the system size. System Clock Generation Module DS1302 clock chip used. DS1302 clock chip to send a single bus, just a line can be completed with the exchange of data between the single-chip, and the high accura Platform: |
