Implement of Modularization Programme Design of PS/2 Keyboard Based on SST89C54
Zheng Zhang · Modern Computer · 2008
Describes the interface and protocol used by PS/2 keyboard and how to design the PS/2 keyboard with MCU.It is a hierarchical structure design and modularization process technique that programs the application-embedded code in MCU.A hierarchical structure analysis is developed for the application-embedded code,including the PS/2 interface protocol used by keyboard and keyboard scanning technique.Introduces the skill of keyboard design with SST89C54.Accordingly,gives the modularization software implemen for PS/2 communication to PC and scanning all keys.
