OLED显示器不能与teensy3.2板配合使用，但它与arduino UNO配合使用，代码如下：

他们没有编译错误。 OLED甚至没有开启。并且在扫描地址时出现了0X3C。我在谷歌搜索了很多但我认为他们在I2C通信中发出了问题。请帮帮我。

Answer 1

@vasu嗨，我遇到了同样的问题，但在回答我的问题之前，请同时检查是否有硬件故障。我购买的OLED显示屏只有VCC-GND-SCL-SDA。因此，我这里没有重设PIN。但是oled库最初会在启动时尝试将重置PIN拉高。由于我没有复位引脚，因此它坐在那儿等待复位为高电平。因此，为了在不使用复位引脚的情况下初始化oled显示，请在Arduino草图文件中尝试

 //1-->Manually set HIGH to digitally assigned reset pin

        pinMode(A4, OUTPUT);  //A4 is reset pin assigned programmatically (for example)
        digitalWrite(A4, HIGH);       



    //2-->Try changing your init to this

        U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE);

        //As this will be the right one to define from the user manual shown in the link
        //https://reprap.org/forum/file.php?267,file=54605

尝试上面的方法，让我知道如何进行。
