Hi,
I purchased 2.3 128x32 monochrome oled. Following the SPI wiring diagram correctly I got no results from the ssd1305test. no errors on screen for code and all wires are connected according to specifications.
The oled won't turn on or run script. It may be a faulty oled could i get a replacement for the price i payed.
Thank you

If your photo app does not support resizing there are plenty of free online sites that will do it. 800x600 is a good size to aim for.

Re: 2.3 128x32 monochrome oled
Looks like you are missing a couple of connections there:
* Connect Pin #8 (DIN) to digital #11 via the level shifter (green wires)
* Connect Pin #15 (CS) to digital #10 via the level shifter (yellow wires)
Also, it looks like you might have the level shifter chip reversed. The notch or dot indicates pin 1 on the chip and should be facing to the right as in the photo below:

Re: 2.3 128x32 monochrome oled
the image quality does not show it but im certain it's all connected and properly orientated. I've rewired this multiple times according to all instruction provided.
No result or indication of it working.
Could it be faulty do i need a new one?

Try reversing the chip. It will not work connected backwards.
