Here's a python library to use with the SSD1322 256X64 display (ER-OLEDM032-1) and a Raspberry Pi2/3.

This library was originally created by TopherCantrell, i just added some enhancements (with his permission), drawing shapes, fonts added, etc...

Reference Manual

ER-OLEDM032-1W display from Buydisplay.

The ER-OLEDM032-1 is a 256x64 graphical OLED display. Each pixel is a 4-bit gray-scale value. The display board has four different interface options (8-bit parallel for 6800 series microprocessor, 8-bit parallel for 8080 series microprocessor, 3-wire SPI interface and 4-wire SPI interface), the default interface is 8-bit 8080 parallel. I used the 4-wire SPI mode in this project to connect the display to the Pi2.
