Learn how to use PWM on an STM32 microcontroller to control a standard servo motor (0°–180° movement), configured using STM32CubeMX and implemented in Keil with HAL libraries.

🧰 This tutorial covers:
- Configuring Timer and PWM channels in CubeMX
- Generating a 50 Hz PWM signal (~20 ms period)
- Translating pulse widths (0.5 ms to 2.5 ms) into servo angles
- Starting PWM in firmware using HAL_TIM_PWM_Start()
- Dynamically adjusting position using __HAL_TIM_SET_COMPARE()
