Controlling an OLED display based on the SSD1306 driver using I2C in CircuitPython

If you’re diving into the world of the CircuitPython NRF 5280 module , you’ll likely find it paired with a nifty expansion board.
This board makes your life easier by allowing straightforward connections for the I2C and SDA pins found on the right side.
And when it comes to displaying information, the OLED display is a great match, especially as it works seamlessly with the SSD1306 driver —it fits perfectly with the pin map for the OLED port.
Just remember, making sure all connections are secure is key; it’s super important to follow the steps carefully for a stable setup.
Also, don’t rush when inserting the module—take your time to align it properly and you’ll be good to go!.

Alright, let’s dive into the fun world of OLED displays! First off, we kick things off by wiping the old code clean and starting fresh to keep things tidy.
Then, we get our hands dirty by importing some key libraries, like I2C and the trusty SSD1306 driver – these are must-haves for working with OLED screens.
Next, it’s all about setting up the gears: configuring pins, especially the clock pin, is crucial because it handles the data flow.
Plus, we need to set the resolution at a nice 64 out of 128 to get the visuals just right.
By using the I2C interface , we can manage the device address, allowing us to perform operations from zero up to 30.
Finally, the fun part: we fill the display with zero, which basically darkens the screen to show that everything’s been reset.
If we ever need to switch things up, we can easily transform the display to a bright white, signaling a total reset.
How cool is that?.

Drawing on an OLED screen might sound complicated, but it’s pretty straightforward! You start with the command display pixel X Y1 to place a pixel precisely where you want it on the screen.
Yes, there might be a bit of flexibility with display settings, but you should see a nice little dot at your chosen spot.
If you want to make a horizontal line, just use display H line 50, 201, and bam! You’ve got a line going from point A to B.
Want to venture into rectangles? Use display left 5, 15, 20, 11 and watch it come to life! And if circles are your thing, try display circle 50, 15, 10.
These commands really show off how versatile this whole setup is.
The best part? You can even input text, letting you customize your display with your own words after the system matches them with the right font.
How cool is that?.

In this session, we dove into how to control an OLED display using the SSD1306 driver through the I2C interface, all in CircuitPython.
It was pretty hands-on and a great way to get started with some cool tech! Looking ahead, we’re planning to roll out even more valuable content that will encourage viewers to dig deeper and explore additional learning opportunities.
So stay tuned for future sessions!.
