Bare-Metal STM32: Writing Registers Without HAL

In this video, I walk through programming the STM32 MODER register using pure bare-metal C 🖥️⚡—no HAL, no libraries. 🛠️ Board I Use: STM32 Nucleo L4 — https://amzn.to/4rqbhJZ While the example focuses on GPIO MODER, the same techniques apply to any STM32 register 🔧💡. Once you understand this, you can confidently read from and write to other peripherals like timers ⏱️, UART ✉️, and more. This tutorial is perfect for anyone learning embedded systems 🛠️ who wants to see how C code maps directly to STM32 hardware. Mastering the MODER register is the foundation for mastering all STM32 register programming 🚀📘. ⚠️ Educational content only. Code shown may contain bugs or errors.
