Abstract

Due to no SPI serial bus interface in MCS51 scm,MCS51 scm couldn't use SPI bus interface apparatuses.The paper firstly introduced the characteristic and Sequence of SPI serial bus.Take double CPU communication as example,the paper implemented SPI serial bus interface communication making use of interrupt on MCS51 scm.Then the paper showed the method and software design program.The slave computer could implement SPI interface and other operation tasks.
