I'm using a STM32F373VCT6 and I have a problem with VBAT and ADC.
I have connected a CR2032 Batterie to the VBAT-Pin.
The RTC works fine with the batterie when the main power ist lost.
But if I try to measure the VBAT-Voltage with the internal ADC1 I get always 0.
The sampling on all other channels works fine; only the ADC_CHANNEL_VBAT gives this value.
Is there anyting else to do to measure the VBAT-voltage with the internal ADC1?
I'm working with CubeMX4.22.1 and CUBE V1.9.0.
