STM32U5 internal RTC time greater than 24 hours

We are using the STM32U5 MCU and its internal RTC in our project.We are facing an issue where the RTC time sometimes goes beyond 24 hours — for example, we observed a timestamp showing 37 hours. The RTC is configured in 24-hour format, and we have in...

Resolved! STM32H5 ADC Measuring VREF+

Good morning,I would like to measure the supply voltage on an STM32H573RI. To do this, I measure VREFINT and then want to calculate the supply voltage.My approach (simplified):sConfig.Channel = ADC_CHANNEL_VREFINT; sConfig.Rank = ADC_REG...
