This post should give you the correct wiring

Adafruit SSD1306 [SOLVED]

If building in Particle Build (Web IDE) you need to change the includes in the demos to // e.g. ssd1306-128x64-spi.ino #include "Adafruit_SSD1306/Adafruit_GFX.h" #include "Adafruit_SSD1306/Adafruit_SSD1306.h" If building with Particle Dev or CLI just leave them as they are For all IDEs do the wiring like this // use hardware SPI // OLED_D0 -> A3 (SPI CLK) // OLED_D1 -> …
