1.连线 我使用的是Arduino(UNO)开发板和LCD1602带拓展板I2C。具体连线比较简单。 GND --- 地线 VCC --- 电源5V SDA --- I2C 数据线 SCL --- I2C 时钟线 2.安装库 arduinoIDE里面有专门为lcd1602编写的库,打开项目->加载库->搜索LiquidCrystal_I2C 3.查找串口地址 首先需要知道LCD的串口地址,之后会用到 ...

ESP8266驱动I2C 简介 本指南演示如何使用使用 Arduino IDE 将 0.96 英寸 SSD1306 OLED 显示屏与 ESP8266 一起使用。我们将向您展示如何编写文本、设置不同的字体、绘制形状和显示位图图像。 我们将在本教程中使用的 OLED显示屏是 SSD1306 型号:单色
Arduino IDE Sanki Notes Scan I2C Address THIS IS OLED 0.9 and 1.3 inch I2C Address CHANGING I2C ADDRESSES: SOME I2C interfaces have pins (or solder pads) that can be changed to change the address. They are usually labelled A0-A1-A2 . Here's the way addresses change from a default 0x27...
