STM32 PWM Without HAL Libraries | Full Tutorial

Описание: 🧠 Bare-Metal STM32 Series: PWM from Scratch

⚠️ Problem:
❌ Only digital ON/OFF control
❌ No LED dimming
❌ No motor speed control
❌ No PWM driver

✅ Solution:
✔️ Build PWM from scratch using STM32 timers
✔️ Understand how PWM actually works
✔️ Write a reusable bare-metal PWM driver
✔️ Control LED brightness and motor speed

🛠️ Board I Use: STM32 Nucleo L4
