HAL Library 26- Power Voltage Detector (PVD) for STM32Fxxx

Power Voltage Detector (PVD) can be used to detect if power voltage is below or above selected voltage. It can be used for closing file using FATFS when detected voltage below treshold so you don’t break data on card or similar thing, sky is the limit here.

PVD allows you to select 8 voltages between 2 and 3 volts. For detailed voltages, check reference manual.
