The Realization of an Extensible System Based on MCS51
Liang Fang · Computer Knowledge and Technology · 2007
This paper discusses two elementary principles of using MCS51 to design circuit, which are storage unexpanded and priority, and gives idiographic circuits and realized assembler of digital clock. In the scheme, display adopts the software decoder and the dynamic scanner, and time can be adjusted by using a keyboard, which keyboard works under the interruptive mode. This scheme is simple and extensible.
