HAL Library 17- IWDG for STM32Fxxx

Sometimes you need watchdog timer to look at your system if it gets stuck. I made a little library to work with it and to be compatible with HAL based drivers.

IWDG timer in STM32Fxxx device has its own clock which is independent from main system clock. You have to constantly reset it’s counter value or it will elapse and reset MCU.
