单片机电子时钟，是利用单片机技术实现计时、时间显示、时间调整、定时调整、闹铃等功能。完成该项目能够有效的训练大家的单片机应用能力，电子时钟的设计过程中，除了应用单片机前六课题的基础知识外，还使用了外部中断技术、定时器中断技术、键盘查询及动态显示技术，希望大家通过该项目的设计，对单片机应用技术有一个较深的认识-Single-chip electronic clock, single-chip technology is the use of time, time display, time adjustment, timing adjustment, alarm and other functions. Completion of the project can be an effective single-chip training capabilities all, electronic clock in the design process, in addition to the application of single-chip based on the first six issues of knowledge, but also the use of the external interrupt technology, technology timer interrupt, keyboard inquiries and dynamic display technology, we hope that through the project' s design, the application of single-chip technology has gained a better understanding of a
