I don’t know either but I don’t think this is an easy task for a beginner. Do you have any experience with SPI?
Why not get a display with HDMI connector? (The 2w has a mini-HDMI interface).

Summary of Pin Mapping:

  • VCC: 3.3V (Pin 1 or Pin 17)

  • GND: Ground (Pin 6 or Pin 9)

  • CS (Chip Select): Pin 24 (PI5)

  • RESET: Pin 36 (PI16)

  • DC/RS (Data/Command): Pin 37 (PI15)

  • MOSI: Pin 19 (PH7)

  • SCK (Clock): Pin 23 (PH6)

  • LED (Backlight): 3.3V (Pin 1 or 17)

Then you need to enable SPI, install the driver for the display and some library to communicate via SPI (like spidev) and mirror the output to the frame buffer (with e.g. fbcp).

Good luck

Hope someone can help here. I wouldn’t know either, but I started here. :wink:

Hey! Yes ive been trying to find mini hdmi displays, im looking for a 3.2 inch display with mini hdmi ive been looking forever and i cannot find one. Can you find one for me? Keep in mind my projects shell is a very small and claustrophobic shell, and ill need to power the screen via the 2w itself

Or look at this, its without HDMI and you can mount it directly on the pins
