Learn how to interface the SSD1306 OLED display with an STM32 microcontroller using the I2C protocol, STM32CubeMX, and HAL libraries. In this step-by-step tutorial, you'll see how to configure I2C in CubeMX, write HAL-based code, and display text and bitmaps on a 128x64 OLED screen. This guide is perfect for beginners and embedded developers working on real-time display projects with STM32.
📌 Covered in this video:
- Wiring the OLED to STM32 (I2C)
- CubeMX I2C and GPIO setup
- HAL-based SSD1306 initialization
- Displaying text and images on OLED
✅ Tested on STM32F103 (Blue Pill), but works with other STM32 MCUs.
