Abstract

The invention discloses a method for achieving hot pull and hot plug and electronic devices. The method for achieving hot pull and hot plug is applied to a first device which is connected with a second device through an inter-integrated circuit (I2C) bus. The first device is provided with M I2C components which are connected on the I2C bus based on the I2C protocol. The second device is provided with N I2C components which are connected on the I2C bus on the basis of the I2C protocol. The M and the N are integral numbers larger than zero. The method includes the steps of obtaining error information which carries out I2C communication with the second device, carrying out ergodic operations on the M I2C components and the N I2C components on the basis of the error information, obtaining a great amount of feedback information on the basis of the ergodic operations, and determining that the I2C bus between the first device and the second device is switched off when the condition that the great amount of feedback information all comes from the M I2C components is determined.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method for realizing hot plugging and hot plugging and electronic equipment. Background technique [0002] The I2C (Inter-Integrated Circuit) bus is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripherals. It is a special form of synchronous communication, which has the advantages of less interface lines, simple control mode, small device package, and high communication rate. [0003] Each I2C bus is connected with a host and a slave, and data transmission is performed between the host and the slave through the I2C bus, and multiple components are connected to the host and the slave. However, hot swapping is not supported in the I2C bus protocol specification. Therefore, when the slave machine and the master machine are separated, a deadlock will be caused, so that the data transmission cannot continue. The so-called deadlock: refer...
