Abstract: Aiming at the problems such as the increase of CPU peripheral chips, chip communication requirements, the shortage of communication interface, the communication complexity etc, this paper elaborates the I2C work principle and work process of STM32F37 series microcontroller, with the application of I2C in the multifunctional electrical transducer. It introduces the hardware design, the initialization and the implementation of the data transmission of the STM32F37XX’s I2C interface, analyzes the advantages and characteristics of the interface in data transmission by detailing its sequence, filter set and data reload works. The results show that the I2C interface can transmit data accurately, and it can be set flexibly, with the advantage of interface program portability, simple hardware design etc.
