Design of Olympic Games countdown plates based on AT89S52ZHANG Zi-cong, JIN Yong-xingCollege of Optics and Electronic Technology, China Jiliang University, Hangzhou 310018, ChinaAbstract:A design of Olympic Games countdown plates based on microcontrollers was studied. In this design, the system used AT89S52 as the controlling core to control the clock chip and a serial real-time clock chip DS1302 as the clock chip completing timing. The software realized the control and the integration of separated modules and finally achieved the functions such as the display of Olympic countdown information, the setting of the clock using the keyboard, time showing, etc. This paper presents in detail the algorithm for countdowns.[著者文摘]
