Abstract

The invention is suitable for the technical field of communication, and provides a data acquisition method and system of an I2C bus. The method comprises: configuring addresses of the slave equipmentaccording to a preset sequence; sending an addressing instruction, inquiring each slave equipment in sequence according to the addresses in the preset sequence, wherein the addressing instruction andthe addresses are in one-to-one correspondence; and importing the data collected by the slave equipment into the master equipment. By reconfiguring the addresses of the slave equipment, when the dataof the slave equipment are collected, the addressing instruction is sent, each slave equipment is inquired according to the preset sequence of the addresses, and then the data collected by the slave equipment are imported into the master equipment one by one. The address conflict problem between the slave equipments is solved, and the master equipment can control the slave equipment at the same time.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an I2C bus data acquisition method and system. Background technique [0002] Today, with the rapid development of robot technology, robots are becoming more and more intelligent, and systems are becoming more and more complex. In particular, more and more sensors are used on large mobile robots. The infrared sensors in the prior art generally use the analog communication method, the interference of the analog communication is relatively large, and the sensor is prone to false alarms. [0003] Digital circuits generally use I2C communication (digital circuits have strong anti-interference ability and almost no false alarm rate), and the I2C communication interface of MCU generally only has two channels, and the addresses of I2C communication for multiple infrared sensors are the same, resulting in infrared The address conflict between sensors cannot control mul...
