Deos anybody know how to change UART configuration to send MSB or LSB first? I use STM Cube MX with STM32F446RE.

I am using the RTC of the STM32L4 Discovery board and have noticed that the sub-seconds are counting down. Is there anyone with an idea on how to resolve this issue?

Can anyone please suggest a simple RFID/NFC tag to monitore & read sensor data using STM32 Nucleo board?

I am currently working on an RTOS application that includes RTC, and have observed that there is a clock drift of approx. 25 to 32 seconds after a 24-hour measurement cycle. Additionally, the drift seems to be not linear.I've measured the RTC frequen...

Thank you for providing this information. I'd like to know if there is any configuration that may force the RTC to count up instead of subtracting the value.

The issue has been resolved in HAL_RTC_Init() looses time · Issue #24 · STMicroelectronics/STM32CubeH7 · GitHub as the number of times I reset the MCU had an impact on the drift.Thanks for indicating the main cause of the problem.

I noticed a significant increase in the drift when resetting the board many times. Do you think it would be advisable for me to check the RCC_BDCR?

I am using Discovery kit with STM32L4R9AI MCU and the RTC clock source is LSE 32.768KHZ.I have to investigate whether the drift increases with reset, but the drift also appears without reset.
