Overview

The Digilent PmodOLEDrgb is an organic RGB LED module with a 96×64 pixel display capable of 16-bit color

resolution.

1 Functional Description

The PmodOLEDrgb utilizes a Solomon Systech SSD1331 display controller to receive information from the host

board and display the desired information on the OLED screen.

2 Interfacing with the Pmod

The PmodOLEDrgb communicates with the host board via the SPI protocol. By driving and keeping the Chip Select

(CS) line at a logic level low, users may send both commands and data streams to the display controller based on

the state of the Data/Command (D/C) pin.

PmodOLEDrgb™ Reference Manual As a graphical display interface, users may light up any individual pixel on the OLED, display predefined characters, or even load bitmaps onto the screen. Each pixel can be set to one of the 65,535 colors that are available. The OLED display has a specific power-up and power-down sequence to ensure the longevity of the device. There are two field-effect transistors (FETs) that control the display’s two power supplies.

PmodOLEDrgb™ Reference Manual Although users are welcome to create their own interface code for the PmodOLEDrgb if they so desire, preconstructed libraries that provide functions for initializing the display and rendering simple text and graphics onto the screen exist. They are available on the PmodOLEDrgb example code page and can be used as-is or as a starting point for a more sophisticated graphics library. Any external power applied to the PmodOLEDrgb must be within 2.
