Overview

The PmodOLED features an SPI-controlled

monochrome OLED display, perfect for

embedded applications requiring small,

complex visual output.

Features include:

• a 128x32 pixel 0.9’’ WiseChip/Univision

UG-23832HSWEG04 OLED graphic

display panel

• standard SPI interface

• clock speeds of up to 10MHz

• internal display buffer

Functional Description

The PmodOLED uses a standard 12-pin

connector to display output on a 128x32 pixel

organic LED (OLED) panel. The graphic

display panel uses the Solomon Systech

SSD1306 display controller.

An SPI interface is used to configure the

display, as well as to send the bitmap data to

the device.

The PmodOLED displays the last image drawn

on the screen until it is powered down or a new

image is drawn to the display. Refreshing and

updating is handled internally.

Power Supply

The PmodOLED has two field-effect transistors

(FETs) that control the display’s two power

supplies. The VDDC control toggles the power

to the logic of the display. The VBATC control

toggles the power to the OLED display itself.

These two pins have pull-up resistors that turn

off their respective power supplies when

they’re not being driven. These pins are

configured as outputs and driven low to turn on

the power supply.

The PmodOLED has a particular power-

on/power-off sequence that must be followed

to prolong the life of the display.

Power-on sequence:

1. Apply power to VDD.

2. Send Display Off command.

3. Initialize display to desired operating mode.

4. Clear screen.

5. Apply power to VBAT.

6. Delay 100ms.

7. Send Display On command.

Power-off sequence:

1. Send Display Off command.

2. Power off VBAT.

3. Delay 100ms.

4. Power off VDD.
