Abstract

The invention discloses an information interaction method and device.In the method, first information of first external equipment is determined firstly, and the first information comprises identification information of the first external equipment and at least one first interface of the first external equipment; then, according to the identification information of the first external equipment, determining a corresponding relationship between at least one second interface of the chip and the at least one first interface; if the chip needs to carry out information interaction with the first external equipment, and the information interaction needs to call a second target interface by the chip, determining a first target interface corresponding to the second target interface according to the corresponding relation; and carrying out information interaction with the first external equipment through the first target interface. According to the method and the device, a developer does not need to configure the bus interface of the chip for the external equipment needing information interaction, and compared with the prior art, the configuration operation of the bus interface is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an information interaction method and device. Background technique [0002] The bus is a channel for transmitting information between the chip and external devices. Among them, common bus types include the following: inter-integrated circuit (inter-integrated circuit, I2C) bus, universal serial bus (universal serial bus, USB), secure digital input and output (secure digital input and output, SDIO) bus and a peripheral component interconnect (PCI) bus, etc. [0003] Among them, the chip can use different types of buses to exchange information with different types of external devices. For example, if the chip needs to exchange information with SDIO external devices, the chip needs to use the SDIO bus. [0004] In addition, when the chip uses different types of buses to exchange information with different external devices, the bus interfaces called are ofte...
