Title:
I2C BUS COMMUNICATION CONTROL METHOD, DEVICE AND SYSTEM, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/258748
Kind Code:
A1
Abstract:
An I2C bus communication control method, device and system, and a readable storage medium. The method comprises: receiving configuration information of an I2C bus sent by an upper-layer application; analyzing the configuration information to obtain a plurality of polling parameters; writing the plurality of polling parameters into a polling table; and controlling the I2C bus, and executing a corresponding read-write operation according to the polling table. In the method, the read-write operation executed on the I2C bus is performed according to the polling table, thus an accurate communication condition of the I2C bus can be directly obtained on the basis of the polling table without accessing a bus state in a polling manner; congestion risks can be reduced, and the access efficiency of a single main device can also be achieved when a plurality of main devices exist. The method facilitates management and maintenance; and if hardware or function change occurs, only the polling table needs to be updated, a program does not need to be modified, and function update or hardware replacement can be quickly adapted.
