#79257 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:
Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,7)

load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d
vbb28d4a3
~ld


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. :)
