STM32F401 Bare Metal Tutorial | Direct Register Programming | GPIO output Part 2

In this video, we learn **Bare Metal Programming on the STM32F401 microcontroller** by working directly with hardware registers — without using HAL, libraries, or external frameworks. Bare metal programming helps embedded engineers understand how microcontrollers actually work internally. Instead of relying on abstraction layers, we control peripherals directly through registers. In this tutorial you will learn: • What bare metal programming really means • How STM32 registers control hardware peripherals • How to configure GPIO using direct register access • How to write minimal embedded C code for STM32F401 This video is part of a **bare-metal STM32 series**, designed to help beginners and intermediate engineers build a strong foundation in embedded systems. Microcontroller used: **STM32F401** If you want to truly understand microcontrollers instead of just using libraries, this series is for you. 🔧 Topics Covered: STM32F401 Bare Metal Programming Register Level Programming GPIO Configuration Embedded C ARM Cortex-M4 📌 Future videos in this series will cover: Timers Interrupts SPI / I2C Display interfacing and more STM32 internals.
