Detailed Description

• ID: ssd1351
• Name: SPI-based OLED Display
• Category: display
• Manufacturer: adafruit

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

    // Initialize display with pins
    // oc = 0, dc = 1, r  = 2, si = 11, cl = 13

        }
