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.
- Detect voltage rise or drop with interrupt
- STM32Fxxx HAL
- defines.h configuration file
Functions and enumerations
Full functions and enumerations can be found on PVD API site.
Examples for receiver and transmitter with or without interrupt pin are available on my Github account, where you can take a look at main.c file for more informations.
