I2C_LCD 上面的例子使用LCD接线比较多,下面介绍一种I2C_LCD,接线只需要4根 首先你需要有一个I2C封装的1602LCD,通过PCF8574T转接板来转接。如图: I2C_LCD 引脚说明 GND —— 地线 VCC —— 电源(5V or 3.3v 电源不同显示效果有点差别) SDA —— I2C 数据线 ...
首先,把转接板焊接到LCD显示屏上(方向如上图) 如果你的A4,A5口已经被占用,那么你还可以接到Arduino最上面的两个没有标文字的IO口,即D0-D13那一排最上面的那两个口 SCL -> 最上面的口 SDA -> 第二个口 扫描I2C地址 将以下代码拷贝到Arduino IDE,并执行。然后选择工具->串口监视器,把右下角的波特率改...
