How to display any image on OLED display

 Here is short tutorial on how to display any image on OLED display. 

You should be familiar with basic of displaying text on OLED display with Arduino or some kind of microcontroller. For those who wants to follow this tutorial can read my previous blog post on how to use OLED display with Arduino. Specifically, there are two types of OLED module driver, the SSD1306 and the SH1106 drivers. For my case my OLED did not work the the SSD1306 driver so I used the SH1106 library. Below is the link to the tutorial:

Beginner's Guide to Testing an OLED Display with Arduino

Once you have a working hardware and program working you can follow the steps outlined here to display picture on the OLED screen. So here I am using 1.3 inch OLED screen. The circuit diagram below shows how to interface the OLED display and Arduino Uno.

The picture above also shows the actual picture being displayed.

The first thing to do is to have your picture converted to byte oriented code and then paste that picture byte code in your Arduino Sketch.

Here for example, I have used the following picture and generated that image byte code and then pasted in the arduino code.

Then go to the following url to convert your image to arduino readable byte code.

As shown in the image below, choose and upload your picture. Set the canvas size to 128 pixel by 64 pixel. Then see the preview of your image and if everything is fine click on the generate code button. Then click on the copy button and paste it in your Arduino code.

Below is an example of the arduino code that is generated by the above online image to byte converter for OLED LCD Display.

Now copy the code and paste it in your Arduino code. The complete code is below.

Now upload it and you should see your image being displayed. You should note that in the above code there is bit of animation of the image.

See also the animation of the prototyping and check the validity of the program code for custom image display with the help of electronics design software Proteus Professional.

 And below is video showing the actual physical demonstration of image displayed on OLED display.
