摘要
系统以单片机为控制部件,实现了日历时钟、定时、报警及汉字显示等各项功能.介绍了系统的软硬件结构及工作原理,并对十六路动态扫描电路及驱动芯片UNL 2003A、74HC 595的结构、技术参数和工作状态进行了分析.
The system is controlled by SCM,which realized the functions of calendar clock, timing, alarm and Chinese characters displaying. The structures and working theories of software and hardware are introduced. The sixteen dynamic scanning circuits and the aspects of the structures, technical parameters and working states of driving chips UNL2003A/74HC595 are analyzed in detail as well.
