I2C Example

[中文]

I2C is a dedicated two-wire serial communication peripheral that supports master-slave data transmission. It can be used to connect various sensors, memory, and displays for data collection and control.

For basic knowledge and configuration instructions about I2C peripherals, please refer to I2C Interface. This document explains the general configuration process and implementation methods of specific functions through the I2C peripheral examples provided by the official ESP-IDF, helping to learn and master the use of I2C peripherals.

For ease of understanding and use, the content of the document is divided into two parts:

  1. General Steps Document: Summarizes the basic usage process of I2C peripherals (such as initialization, configuration, startup, etc.), providing unified step instructions and API references.

  2. Example Document: Explains the implementation of each example by function, the common parts avoid repetition by referencing the general steps document, only retaining the logic and parameter settings unique to the example.

This layered structure facilitates understanding the relevant basic knowledge and overall process in the general steps document first, then learning the implementation details of specific functions in the example document, thereby understanding the working principle and program design method of I2C peripherals more efficiently.
