SSD1306 OLED I2C Display with Nucleo STM32F446RE using STM32CubeIDE

Prerequisites

This project assumes you have already installed STM32CubeIDE. You need to have previously done a basic blink sketch with Nucleo STM32F446RE using STM32CubeIDE. I have made a complete video from installing STM32CubeIDE to LED blink program. You can watch it by clicking this link. https://www.youtube.com/watch?v=oAwZ0cjlmN8

Wiring Diagram

STM32CubeIDE Settings

Click connectivity --> Click I2C1

For I2C select I2C

Configuration --> Parameter Settings

For I2C speed select Fast Mode

Set PB8 to I2C1_SCL

Set PB9 to I2C1_SDA

Libraries

Inside Core/Inc Folder

Inside Core/Src Folder

Additional code on top of STM32CubeIDE generated code (main.c file)
