Hi Georgi,

While translating (verbose build) I'm getting the following error message.
Could you please help with it? I'm not an experienced developer.

C:\Users\cskocsis.platformio\lib\Adafruit SSD1306_ID135\Adafruit_SSD1306.cpp:482:47: error: 'digitalPinToPort' was not declared in this scope
dcPort = (PortReg *)portOutputRegister(digitalPinToPort(dcPin));

Arduino IDE or PlatformIO?

somewhere is defined _ _ AVR _ _
https://github.com/adafruit/Adafruit_SSD1306/blob/76a2a1fc0015f211670afde51908de1b5aaec95e/Adafruit_SSD1306.h#L43

and this define HAVE_PORTREG

fast workaround: "hack" the Adafruit_SSD1306.h at the begining
#undef _ _ AVR _ _

Thank you so much! It's working now.
Although, the image is not correct.

Could you still help in this, please?

Thanks! :)

or try clear display buffer

[Wiz-IO]

and look your display - there is 5 to 3.3 voltage regulator - bypass it

[Wiz-IO]

and if you use I2C/SPI periphery do not init before sim-ready ( Mediatek bug )
https://github.com/Wiz-IO/platformio-quectel-examples/blob/master/Arduino/bc66/i2c_oled/src/main.cpp#L74

without sim - no problem
