Frequently Answers and Questions

What are the functions of the Window Watchdog (WWDG) and Independent Watchdog (IWDG)?

The WWDG and IWDG are timers that reset the microcontroller if they are not refreshed within a certain time limit. This prevents the microcontroller from getting stuck in a loop or malfunctioning due to software or hardware errors.

What is the Clock Security System (CSS)?

The CSS monitors the High Speed External (HSE) oscillator. If the HSE oscillator fails, the CSS automatically switches to the Internal High Speed (HSI) oscillator, ensuring that the microcontroller continues to operate.

How do I simulate malfunctions on the development board?

You can use the two buttons on the board to simulate malfunctions. Pressing one button can cause a software failure, while pressing the other can simulate a hardware failure. This lets you test how the WWDG, IWDG, and CSS handle different scenarios.
