I2C和SPI是两种非常流行的串行接口总线。本教程将介绍使用I2C连接Arduino和LCD驱动模块,但是LCD驱动模块也可以连接SPI接口。您可以通过跳接驱动模块上的焊接跳线(图2:LCD驱动模块上的焊接跳线)来设置I2C地址(A0、A1、A2)或使能SPI(SPI使能)。本教程中使用I2C的唯一电路是LCD驱动模块,所以我们不需要更改当前配置。这意...
转到链接 并下载库 Arduino-LiquidCrystal-I2C-library。然后打开 Arduino IDE 并转到Sketch>Include Library> Add.ZIP Library 。接下来选择下载的 ZIP 文件并单击打开。 第4步 接下来创建草图。首先,我包含标题“Wire.h”。该库有助于与 I2C 设备进行通信。然后包括“LiquidCrystal_I2C.h”以更好地与显示器通信...
