Detailed Description

Example application: Generate PWM on PB10 using TIM2 and print duty cycle over UART2.

• Initializes SysTick timer with 40 µs tick.
• Initializes UART2 at 9600 baud.
• Configures PB10 as alternate function (AF1) for TIM2_CH3.
• Initializes TIM2 for PWM output using HAL PWM driver.
• Continuously ramps the duty cycle from 0% to 100% and prints it over UART2.
