Micro OLED Examples
Note: The following examples has been updated to reflect changes in the Micro OLED Arduino Library.
Example: Feature Demo
This first example demonstrates many of the available features of the screen through several applications. Keep in mind when looking at this example that drawing anything takes two steps. You must first write what you want the screen to display into the screens memory, then you must tell the screen to display what is in its memory.
To begin, we must include our Wire library to use I2C, and the SFE_MicroOLED library to control the screen. The code also includes modular functions to tell the microcontroller how to print each example. This is a good place to look to see examples of how the functions discussed earlier are implemented. The example code will then loop between all of the examples. This is a good way to see exactly what your code looks like on the screen.

SFE_MicroOLED Library Demo
Paul Clark @ SparkFun Electronics
Original Creation Date: December 11th, 2020
This sketch uses the MicroOLED library to show all the functionality built into the library
using the begin function defined in version v1.3 of the library - which allows different
TwoWire ports and custom I2C addresses to be used.
If you are using the standard Micro OLED display, its I2C address will be 0x3D or 0x3C
depending on how you have the D/C or ADDR jumper configured.
Hardware Connections:
This example assumes you are using Qwiic. See the SPI examples for
a detailed breakdown of connection info.

The example code will look something like the GIF below.
Example: Drawing Bitmaps
It is also possible to load bitmaps of your own custom images into the screen. This can be done using this Bitmap generator. The tool is pretty self explanatory, just load in an image, tell the tool that your screen is 64x48, go to File, and Save the output.
Open the file generated as a text file, it should look something like the below image.
This array is the image that will be displayed by the screen, so now we just have to paste it into the bitmaps.h header file as the correct data type so our compiler is able to find the image. Make sure you change the array to a uint8_t. The pasted bitmap should look something like the below image, with the variable type changed to uint8_t.
You will also need to change the name of the array when referencing them in the example code. In this case, we named it rick and morty.
