Code issue

[CorydoraSterbai4343]

This part of the code won't compile : LCD_SH1106_SDA -> A4 (I2C SDA) LCD_SH1106_SCL -> A5 (I2C SCL) It needs #define added at the begienning like this : #define LCD_SH1106_SDA -> A4 (12C SDA) #define LCD_SH1106_SDA -> A5 (12C SCL) Only then it'l work fine. (This is labeled SH1106 but it works for SSD1306 too. It's used to define 12C pins.) For more detail this is the error : Arduino: 1.8.19 (Windows 10), Board: "Arduino Nano, ATmega328P (Old Bootloader)"

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. This is the raw error , I only changed the name because it was my real one and i can't show it. WARNING! By default this part comes commented so it's not an issue. Only if you want to use an SSD1306 or SH1106 it's a problem.
