30 FPS Video on SSD1106 OLED Display

0.96" OLED 64x128 Display Module

OpenCV

Arduino IDE

Arduino Nano R3

<p >I wanted to push the limits of the OLED display. The SSD1106 is usually used for displaying text and some animations for simple projects. I wanted to see if real-time video could be streamed to the display. There were a lot of hurdles faced in this project. The most limiting factor was the bandwidth of the LED - micro-controller interface. I had to overclock the SPI connection to 2MHz using a fast and optimized library to be able to get enough bandwidth to transmit video. The UART interface that is used to receive the video from the computer runs at 1MHZ.</p><p >Another problem is that the OLED displays only have two colors, off and on. You cannot get gray scale video out of it. I tried to use dithering to get the illusion of shaded of gray. It works pretty good in my opinion. Let me know what you think of the project!</p><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/aljv_NSFFC8" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Demonstration Video</div></figcaption></figure></div><p ><br ></br></p>

30 FPS Video on SSD1106 OLED Display

I wondered if the SSD1106 can be used for more than text & simple graphics. After a bit of overclocking I managed to stream video at 30 FPS.
