So my OLED with Wemos D1 Mini is not working...

This isn't my first rodeo - I've troubleshooted issues with ATMEGAs, Arduino, PIC32, etc and I'm a software dev by day so please don't count me out as being a noob!

All test programs I've found upload just fine, but then nothing happens.

What I've done:

I've soldered all pins and continuity tested every pin.

I'm using the version of SSD1306 from here https://github.com/mcauser/Adafruit_SSD1306/tree/esp8266-64x48 and even have it referenced from the local project folder.

I'm not using D4 or D5 but have changed OLED_RESET for every value anyhow just out of frustration (it was a suggestion out ther).

After upload get this in the serial monitor if it means anything to anyone:


I'm uploading via the Arduino IDE - are there some special settings I need to use?

Thanks in advance. I'm new here, just desperate to get this to work. I spend most my time doing home automation stuff using Wemos. So please let me know if I'm breaking any rules or such, or being impolite.

Did you get it to work?

I tried several libraries and none of them seem to work...
