Controlling an OLED display with a Raspberry Pi Pico using MicroPython

So, we’re diving into a project where we’ll be controlling an OLED display using the SSD1306 driver, and we’re going to do this through the I2C protocol with a Raspberry Pi Pico.
First things first, it’s super important to properly insert the Raspberry Pi Pico into expansion mode if you want to get this setup rolling smoothly.
Once that’s done, you’re on the right track to making things pop up on that display!.

When you’re setting up your Raspberry Pi Pico with an OLED display, it’s important to remember that it runs on a 3.3V power supply.
You’ll be working with three key connections: GND, SCL, and SDA.
Now, in the world of I2C communication, SCL is the clock signal, while SDA is the line for sending data.
For your hardware setup, GPIO 10 is typically used for the SDA line, and GPIO 11 is for SCL.
But here’s a cool tip: MicroPython actually lets you swap these connections if you need to, so you can use software-based I2C communication.
Just make sure you connect your OLED display according to the instructions for everything to work smoothly!.

Setting up the SSD1306 module is easier than it sounds! First off, you’re going to want to create some specific files in your library folder.
You’ll need to grab the source code for the SSD1306 module from a provided link and copy that over.
Once you’ve got that, pop a new file named ssd1306.py into the right directory and don’t forget to clear the main file before you insert the copied code to make sure everything runs smoothly.
And just like that, you’re on your way to utilizing your display!.

Hey there! The latest and greatest version of Ray, called H21, has just dropped and is all set for you to dive into.
So, CircuitPython used to have a bunch of cool commands, but if you’re rolling with MicroPython on the SSD1306, you’ll notice that the circle command is missing.
The only command that’s made it through successfully so far is the rect command.
But don’t sweat it too much; the program still does a fantastic job of displaying pixels, lines, rectangles, and text effortlessly on the OLED screen.
Just keep in mind that there’s still some testing to do, especially for showing text smoothly on the display..

Let me tell you, this setup opens up a world of creative possibilities, letting you dabble in all sorts of graphical outputs and interactive designs.
The Raspberry Pi Pico is a fantastic choice whether you’re just starting out or you’ve been around the block a few times - it’s powerful yet super user-friendly.
One of the cool things about it is that with MicroPython, you can whip up some simple code that makes your ideas pop on the OLED display.
So, whether you’re brainstorming or already working on a project, controlling the OLED with MicroPython on the Pico is definitely doable, proving just how practical this whole setup really is..
