Unlock STM32 Peripherals! GPIO Alternate Function Made Simple (Bare Metal) No HAL library
🚀 Struggling to use STM32 Timers with GPIO pins?
In this video, you’ll learn how *GPIO Alternate Function (AF)* works at the register level using *bare metal programming* — no HAL, no shortcuts.
🔥 We’ll specifically configure **Timer functionality using GPIO Alternate Function**, so you understand how peripherals connect to real pins.
---
🔥 By the end of this video, you will:
✔ Understand what Alternate Function really is
✔ Configure GPIO registers (MODER, AFR) step-by-step
✔ Connect GPIO pins to *Timer peripherals (PWM / Output Compare)*
✔ Write clean bare-metal code for STM32

💡 This is a must-watch for:
Students learning Embedded Systems
Beginners in STM32
Anyone who wants to move beyond HAL
