I2C只需要两个引脚,不管连接几个I2C设备都是使用SDA和SCL。这使得它在连接多个设备时非常方便,因为它占用的引脚相对较少。 I2C 与 SPI 的 SDA 不一样 • SPI的SDA:在SPI通信中,SDA通常指的是MOSI(Master Out Slave In),全称是"Master Out Slave In",表示主设备输出数据给从设备。

I2C LCD1602的蓝色电位器用于调整背光以获得更好的显示效果。I2C仅使用两个双向漏极开路线,串行数据线(SDA)和串行时钟线(SCL),通过电阻上拉。使用的典型电压为+5V或3.3V,但允许使用其它电压的系统。 线路图 LiquidCrystal_I2C库 将LiquidCrystal_I2C 库拷到arduino IDE 下的 libraries 目录下。
