Guide du débutant pour le prototypage d'écrans

In this guide, you’ll learn how to locate example code and upload it to your microcontroller for prototyping with your display. This article is meant to be used as a tutorial using our 4×20 character OLED, but you can apply this guide to all of our displays.

There are two places you can look for free example code to help you get started:

Finding Example Code in our Code Library

From our website, head to our Support Center to locate hundreds of free example code written by our engineers, designed specifically for our displays. These resources are organized by display type, but feel free to use the search bar to locate a specific part number that you are looking for code on. Here's a quick step-by-step guide to reference:

  1. From our website, click Support Center or go to support.newhavendisplay.com
  2. Click on the Example Code category button
  3. Browse code by display type and view all articles in the category if needed to expand what's available
  4. Find the part number you need and click into the article to view the example code
  5. Copy the code and paste it into your integrated development environment (IDE)
  6. Edit the code and/or upload it to your microcontroller

What is GitHub?

GitHub is a repository for open-source software where users can find code examples for our displays. You’ll find a wide variety of example codes here available for free. Using these codes will help you see the different features and functions our displays are capable of.

Go to Github on your computer

Finding Code on GitHub

Let's get started! Follow these steps to navigate through GitHub and upload example code to your display.

1. In the "find a repository" search bar, enter the display part number to see available code. You'll see results start to populate as you type. The part number for our 4x20 slim character OLED is "0420cw" Step 1 of GitHub tutorial
2. Click to open the repository. Step 2 of GitHub tutorial
3. Open the demo code folder and find the .ino file inside. Step 3 of GitHub tutorial
4. The full code will expand when you click the .ino file. Now you can copy the code directly from the page and paste it into your IDE. Be sure to copy the entire code beginning to end. Step 4 of GitHub tutorial

Upload Your Code to Arduino

1. Open the Arduino IDE and paste the copied code into the program. Step 5 of GitHub tutorial
2. Open the tools tab to verify that the correct Arduino board and port are selected for uploading. Step 6 of GitHub tutorial
3. Click the arrow button in the top left corner of the window to begin uploading the program to Arduino. Step 7 of GitHub tutorial

When the code is finished uploading, you will see the result on your display.

Congratulations!

You communicated with our 4x20 slim character OLED.
