STM32-IIC 配置解说（原创）STM32 - I2C 简介 ：I2C 总线接口连接微控制器和串行 I2C 总线。它提供多主机功能，控制所有 I2C总线特定的时序、协议、仲裁和定时。支持标准和快速两种模式，另外 STM32的 I2C 可以使用 DMA 方式操作。本文主要以一个实例来介绍 STM32-I2C 的配置方式和具体在工程中通过调用哪些库函数来实现 I2C 器件的通信。实例：写入数据到器件 AT24C02 并将存入的数据读出好，我们先来讲讲 STM32 I2C 模块的端口基本配置，由 STM32 中文参考手册可以查到在使用 I2C 时对应的引脚要配置成哪种模式。 SCL 和 SDA 引脚都配置成开漏复用输出(THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS
