I bought this OLED from eBay, but cannot figure out how to get it to work with the ESP8266.

Any suggestions for a working library? Or can I simply modify SD1306 somehow?

- Sun May 21, 2017 6:11 pm #66168 It's a really nice OLED for a great price (they're about $2,50 on AliExpress), though it's not 128*128 but 128*64 pixels.

I2C address is on 0x3c (not 0x78 like the PCB says) and you can use any good SD1306-library (for instance the one from AdaFruit).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
