Comprehensive multifunctional digital clock system comprising multi-point accurate timing reminding

The invention discloses a comprehensive multifunctional digital clock system comprising multi-point accurate timing reminding. The digital clock system is a medical multifunctional timing clock (hereinafter referred to as a medical clock for short) which uses an S3C2440A chip as a core control component according to the design method. The requirements of the project are analyzed, the medical clockcomprises a starting module, a timing module, a background alarm music selection playing module, an LCD display module and a clock training module. The structural diagram of six functional modules ofthe medical clock is shown in FIG. 1. The S3C2440A serves as a main control chip of the medical clock, and Timer, the TRC, LCD and IO functions in the chip realize various functional modules. Audio output is realized by the aid of a WT58D audio storage playing chip. The practicability of the digital clock system is improved. 本发明公开了种包含多点精确计时提醒的综合型多功能数字时钟系统，该数字时钟系统以S3C2440A芯片为核心控制部件的医用多功能定时时钟(以下简称医用时钟)的设计方法。通过项目的需求分析,医用时钟包括
