I2C总线的Arduino库函数 I2C即Inter-Integrated Circuit串行总线的缩写,是PHILIPS公司推出的芯片间串行传输总线。它以1根串行数据线(SDA)和1根串行时钟线(SCL)实现了双工的同步数据传输。具有接口线少,控制方式简化,器件封装形式小,通信速率较高等优点。在主

I2C Modes & Communication Speeds Originally, the I2C-bus was limited to 100 kbit/s operations. Over time there have been several additions to the specification so that there are now five operating speed categories. Standard-mode, Fast-mode (Fm), Fast-mode Plus (Fm+), and High-speed mode ...
