Connect an Adafruit SSD1351 1.5" Color OLED breakout board to a Particle Photon.
Should be possible, but I haven't yet gotten it working. See https://community.particle.io/t/particle-photon-oled-screen-and-sd-card-demo/18145 and https://github.com/mikeseeh/photon-demo-oled-sdcard for examples where folks have succeeded.
With a small change, this library could be adjusted to work with 1.27 inch OLED, and possibly the 0.96 inch OLED breakout boards.
For hardware SPI (considerably faster), connect the pins as follows:
Photon -> OLED
----------------------
3V3 -> 3Vo (3V)
GND -> GND (G)
D6 -> DC
D5 -> RESET (R)
A5 -> MOSI (SI)
A3 -> SCK (CL)
A2 -> OLEDCS (OC)
DC and RESET may be set to any pin, but the example defaults to D5 & D6.
Any combination of pins may be used for software SPI, but the display will update more slowly.

- The lion's share of the credit goes to Adafruit - https://github.com/adafruit/Adafruit-SSD1351-library
- I started with https://github.com/mikeseeh/photon-demo-oled-sdcard
- Which I think is based on https://github.com/pkourany/Adafruit_SSD1351_Library/
