Timers and PWM (Bare-Metal)

Purpose

Configure MCU timers for PWM output, input capture, and periodic scheduling: prescaler/ARR setup, compare channels, and SysTick as a simple tick source.

When to Use

• Motor/LED dimming via PWM
• Measuring pulse width (input capture)
• Bare-metal millis() without FreeRTOS
• Hardware periodic sampling trigger

Workflow

1. PWM on TIM2 CH1 (STM32)
