STM32 GPIO From Scratch: No HAL, Just Registers

🚀 STM32 Nucleo Blinky — Bare-Metal GPIO (No HAL, No Libraries) Learn how to get started with the STM32 Nucleo (STM32L4) using pure bare-metal programming. In this video, I turn on and blink LEDs by working directly with registers — no HAL, no external libraries. This approach helps you understand how microcontrollers really work and builds a strong foundation for IoT, robotics, and automation projects. ❌ No HAL ❌ No libraries ✅ Register-level GPIO control 🛠️ Board I Use: STM32 Nucleo L4 — https://amzn.to/4rqbhJZ ⚠️ Disclaimer: This is not best practice. ➡️ In the next video, I’ll refactor this into clean, readable, maintainable code. 📚 Watch These First (Prerequisites): ▶️ Reading from & Writing to Registers —    • Bare-Metal STM32: Writing Registers Withou...   ▶️ Register Addressing —    • Direct Register Access Without the Confusi...   ▶️ Hexadecimal —    • Why Binary Fails for Datasheets | Hexadeci...   ▶️ Bitwise Operations —    • Learn These 6 Bitwise Ops Before You Touch...   💻 Get the Lesson 01 Blinky Code Here: https://github.com/equipembedded/STM3... 👍 Like • 💬 Comment • 🔔 Subscribe for more STM32 bare-metal content ⚠️ Educational content only.
