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...

Resolved! UART & DMA overrun error

Hi all.I'm working on a project where my MCU (STM32H755) communicate with a device via UART at 921600 Bauds.Here some details about the environment:The device sends constantly, each second, a log at 921600 Bauds. The MCU sends at same speed some comm...

Resolved! STM32G030 ADC DMA Not Working

Hi all,I am using STM32G030F6P6 and trying to read ADC channel 11 and channel 16 using DMA.ADC works correctly in polling and interrupt mode.When I enable DMA, the ADC values in the buffer remain 0 all the time.DMA does not trigger at EOC, and DMA tr...
