Electronic brick based on I2C interface

Abstract

The invention discloses an electronic brick based on an I2C interface. The electronic brick comprises a base and component blocks installed on the base in a pluggable mode. The component blocks are configured to different addresses; the base is provided with a microcontroller and a single-chip microcomputer for managing the communication data flow between the microcontroller and the component blocks, each component block comprises a first type component block based on I2C communication, the first type component blocks and the single-chip microcomputer are configured to be communicated in an I2C communication mode, and the microcontroller and the single-chip microcomputer are configured to be communicated in an I2C communication mode. Due to the fact that only two data lines need to be arranged between the first type component block and the base, connection is easy, plugging is easy, the child's using difficulty is lowered, the playability is improved, the cost is controlled due to thesimple hardware connection requirement, and the good economy is achieved; an I2C bus can be hooked to multiple peripheral devices, the expansibility is good, the varieties of peripheral modules are greatly enlarged, and product upgrading is more convenient.

Description

technical field [0001] The invention relates to the field of intelligent toys and teaching aids, and more specifically, relates to an electronic building block based on an I2C interface. Background technique [0002] Smart toys are a brand-new market emerging from the rapid development of the electronic information industry, and are the direction of development in the field of children's toys / teaching aids in the future. Electronic building blocks subvert the traditional building blocks in a brand-new way. While cultivating children's hands-on ability, they also expose them to certain knowledge of physics and chemistry, allowing children to have a more perceptual and specific understanding of science. Electronic building blocks overcome many shortcomings of traditional building blocks, make children more interested, bring easy and free electronic DIY experience, and help young children realize their electronic creative dreams. [0003] The data communication between electro...

Problems solved by technology

Among the more popular serial communication protocols such as SPI, UART, I2C, etc., the synchronous communication protocol SPI is full-duplex communication, and according to the protocol, there are MOSI, MISO, NSS, and SCK four-wire connections. Although the data transmission capability is more powerful, However, the hardware connection is relatively complicated, and it is not suitable for use in this product; the universal asynchronous serial communication UART is also full-duplex, and requires corresponding communication modules on both sides of the communication, that is, it is more suitable for use between microcontrollers; The I2C communication protocol has the simplest hardware connection requirements. It only needs one data line SDA and one clock line SCL to complete half-duplex communication. Each device connected to the I2C bus has a unique address identification code. The host can address different slaves according to the address, and the communication between the host and multiple slaves can be realized, which is in line with the design concept of this product.

However, it is true that I2C communication has not been applied to electronic building blocks at present
