Problems solved by technology

[0002] Existing security chips only provide 7816 interfaces, and most of the MCUs in IoT smart devices do not have 7816 interfaces. The 7816 interfaces need to be simulated by software, which greatly increases the difficulty of development and prolongs the development cycle.

Abstract

The invention relates to the technical field of IoT (Internet of Things), and particularly discloses an IoT intelligent device, which comprises a chip, a first micro-control unit and a second micro-control unit, wherein the chip comprises a safety module, a protocol analysis module, an interface control module and an interface communication module; the first micro-control unit is connected with the interface control module through a first GPIO (General Purpose Input / Output) interface and performs data interaction with the interface communication module through an SC_SPI protocol; the second micro-control unit is connected with the interface control module through a second GPIO interface and performs data interaction with the interface communication module through an SC_I2C protocol; when the first micro-control unit and the second micro-control unit both send data to the chip, the chip performs data interaction with the two micro-control units through a concurrent protocol. The IoT intelligent device of the invention supports I2C single interface communication or SPI single interface communication, and also supports dual-interface concurrent communication of an I2C interface and anSPI interface, thus the development difficulty of the IoT intelligent device is simplified, and the development cost is saved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an intelligent device of the Internet of Things. Background technique [0002] Existing security chips only provide 7816 interfaces, and most of the MCUs in IoT smart devices do not have 7816 interfaces. Software must be used to simulate 7816 interfaces, which greatly increases the difficulty of development and prolongs the development cycle. Contents of the invention [0003] An object of the present invention is to provide a smart device for the Internet of Things and a communication party, which supports I2C single-interface communication or SPI single-interface communication, and also supports dual-interface concurrent communication of the I2C interface and the SPI interface, which simplifies the development of the smart device for the Internet of Things Difficulty, saving development costs. [0004] To achieve the above purpose, the present invention provid...
