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.
