class pyupm_ssd1351.SSD1351(oc, dc, rst)

Bases: pyupm_ssd1351.GFX

API for SSD1351 OLED displays.

ID: ssd1351

Name: SPI-based OLED Display

Category: display

Manufacturer: adafruit

Link:http://www.adafruit.com/products/1431

Connection: spi This module defines the interface for the SSD1351 display library. It was tested with the Adafruit 1.5” OLED Display, but should work with any SSD1351 display running in SPI mode.

On the Intel Edison don’t forget to disable SPI Power Management (PM) for this driver to work, you can find more details on this topic here:http://iotdk.intel.com/docs/master/mraa/edison.html
