因此,我们的第一个示例是I2C HEX地址扫描器。 找到I2C LCD显示器的十六进制地址后,我们将相应地控制该显示器,以通过I2C从Arduino或NodeMCU向LCD显示器发送消息。 下图显示了I2C LCD显示屏分别与Arduino Uno和NodeMCU之间的硬件连接。 下表列出了Arduino Uno和LCD显示屏之间的硬件连接关系。 下表列出了Node MCU和LCD...
Arduno的IDE（1.8.13）使用“库管理器”的功能即可在线下载相关库文件，名称叫“LiquidCrystalI2C”。或者单独下载LiquidCrystal_I2C，解压缩后，将文件夹拷贝至C:\Program Files (x86)\Arduino\libraries目录下。LiquidCrystal_I2C lcd(0x27,16,2);初始化对象中有三个参数，分别对应 地址、列、行。地址取决于转接...
