WPI437 1.3 Inch OLED Screen for Arduino

Product Overview

The Whadda product is an OLED display that has several advantages such as low power consumption, high resolution, and a bright, large viewing angle for better readability. It requires a 2.8-5.5 V power supply and has a pin layout that includes SCK clock, MOSI data, reset, data/command, chip-select signal, and ground.

Safety Instructions

Before using the Whadda product, it is important to read and understand the instruction manual and all safety signs. The product is designed for indoor use only to ensure safe usage.

Product Usage Instructions

Before bringing the Whadda product into service, it is recommended to read the manual thoroughly. If the device was damaged during delivery, do not install or use it and contact your dealer for assistance.

To connect the Whadda product:

Connect VCC pin to 5V and GND pin to GND
Connect D0 (SCL) to D4, and RES (reset) to RESET
Connect D1 (SCK) to D5, CS to D6, and DC (data/command) to D7

To upload the sketch:

Go to Files Examples and scroll down to U8glib.
Open the example Graphicstest.
In the sketch Graphicstest, several types of displays can be selected. Un-comment U8GLIB_SH1106_128X64 u8g(4, 5, 6, 7) for WPI437.
Compile and upload the sketch to your WPB100 for usage.

The Graphics test sketch with only the correct driver line for WPI437 is available in the code section of the manual. The product can now be used for its intended purpose.

What is Arduino

Arduino® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a twitter message or publishing online. Surf to www.arduino.cc for more information.

Example

Connection

VCC → 5 V
GND → GND
D0 (SCL) → D4
RES → RESET
D1 (SCK) → D5
CS → D6
DC → D7

Uploading the Sketch

Go to the product page on www.velleman.eu and download the U8glib.zip file. Start the Arduino® IDE and import this library: Sketch → Include Library → Add Zip library. Once finished, go back to Sketch → Include Library → Manage libraries, and scroll down until you find the U8glib library. Select this library and tap “Update”. Now you have the latest version with examples

Go to Files → Examples and scroll down to U8glib. Open the example Graphicstest. In the sketch “Graphicstest”, several types of displays can be selected. Just “un-comment”
the one you need. For the WPI437 you have to un-comment: U8GLIB_SH1106_128X64 u8g(4, 5, 6, 7); Compile and upload the sketch to your WPB100 and enjoy

Code
The “Graphicstest” sketch with only the correct driver line for WPI437 looks like this:

GraphicsTest.pde

Before compiling: Please remove comment from the constructor of the
connected graphics display (see below).
