I'm just starting out with oled's and I think the one I have may be broken. From the Adafruit website tutorial I set up the arduino (I'm using an Arduino Mega 2560) to the SSD 1351 OLED just how it said to in the tutorial. I remembered to adjust the height in the library from 128 to 96 just how the test says and I'm running a test directly from adafruits ssd1351 library so there shouldn't be any code issues. My program compiles but when I press reset there is nothing displayed on the OLED. I'm thinking that the only issue there could be is that the pins need to be set up differently for the mega 2560. Here is how I connected it. I know that I connected it correctly on the breadboard.
GND -> GND (G)
5v -> VIN (+)
#2 -> SCLK (CL)
#3 -> MOSI (SI)
#4 -> DC
#5 -> OLEDCS (OC)
#6 -> RST (R)
Update: this is the website I got the tutorial from: Wiring and Graphics Test | Adafruit 1.27" and 1.5" Color OLED Breakout Board | Adafruit Learning System
