Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] figure 1 For the application scene diagram of the communication method of the internal integrated circuit (English: Inter Integrated Circuit, I2C for short) host computer provided by the embodiment of the present invention, refer to figure 1 , N I2C masters ( figure 1 Among them are respectively I2C master 11, I2C master 12, ..., I2C master 1N) and M I2C slaves ( figure 1 Among them, the I2C slaves 21, I2C slaves 22, ..., I2C slaves 2M) are connected to the I2C bus, N≥2 and N is an integer, and M is a positive integer. The I2C bus includes the SCL (Serial Clock, serial clock) line ( figure 1 Indicated by a thin line) and SDA (Serial Data, serial data) line ( figure 1 Indicated by thick lines) two signal lines, SCL lines of N...

Abstract

The invention discloses a communication method and device of an internal integrated circuit host, and belongs to the technical field of communication. The method comprises the steps of receiving a start bit and the address and write instruction of a second I2C host, wherein the start bit and the address and write instruction of the second I2C host are sent by a first I2C host in sequence; when thefirst I2C host receives the right to use a memory, receiving data sent by the first I2C host in bytes, and storing the data in the memory; receiving a stop bit sent by the first I2C host, and sendingan interrupt signal to the second I2C host; receiving a start bit, a set address and a write instruction sent by the second I2C host in sequence; sending data to the second I2C host in bytes; receiving a stop bit sent by the second I2C host, and making the first I2C host lose the right to use the memory. According to the communication method and device of the internal integrated circuit host, oneI2C host can write data into another I2C host.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication method and device for an internal integrated circuit host. Background technique [0002] The internal integrated circuit (English: Inter Integrated Circuit, referred to as: I2C) bus is a simple bidirectional two-wire synchronous serial bus, including serial data (English: Serial Data, referred to as: SDA) line and serial clock (English: Serial Clock, referred to as: SCL) line two signal lines. The SDA lines of all devices connected to the I2C bus are connected to the SDA line of the I2C bus, and the SCL lines of all devices connected to the I2C bus are connected to the SCL line of the I2C bus. [0003] The devices connected to the I2C bus include at least one I2C master and at least one I2C slave. The I2C master is a device configured in master mode, which can initiate transmission, generate clock signals and terminate transmission, that is, control the d...
