Synchronization time-division multiplexing bus communication method adopting serial communication interface

摘要

A synchronization time-division multiplexing bus communication method adopting a serial communication interface. Both receiving and sending data lines of a host and slaves are respectively connected to a bus. The method comprises: when a host sends a downlink data message correspondingly needed by each slave every time, each slave receiving data by means of an SCI interface, the slave beginning to send an uplink data message after waiting for a time interval, the next slave beginning to send an uplink data message after waiting for the same time interval after the previous slave sends an uplink data message, and so on, thereby achieving the bus communication method.
