Detailed Description

Blink LED on PA05 and print system millis over UART2.

This example demonstrates:

• Initializing SysTick timer with 40 µs tick.
• Configuring GPIO PA05 as output for LED control.
• Initializing UART2 at 9600 baud for console output.
• Initializing TIM5 timer (prescaler 0, auto-reload 1e9).
• Toggling LED and printing system millis in an infinite loop.
