Hello, I'm trying to use the RTC of my NUCLEO-L476RG including the sub-seconds feature. I've activated the RTC clock source in the .ioc and configured LSE as clock source (32.768KHz). I've set up an initial value to the RTC and I'm reading it out eve...

Hello,I've implemented the solution proposed in https://github.com/MaJerle/stm32-usart-uart-dma-rx-tx?tab=readme-ov-file by @Tilen MAJERLE for efficiently using the DMA in circular mode with a buffer for the UART in a STM32L4 board.I'm trying to port...

Thanks @waclawek.jan for pointing me in the right direction. I first got rid of "double" in the intermediate calculation step (although this was a non-optimized testing code).I have researched the HAL_RTCEx_SetSynchroShift function plus the RTC_SHIFT...

Hi @waclawek.jan, thanks for pointing to the appropriate HAL function to perform the shift register update. I've taken a look and seen that the RTC register locking and unlocking is performed inside that function.I've modified my functions as follows...

Thanks for your reply @Karl Yamashita. I think the problem is not setting the UART DMA in Normal or Circular mode - although in my opinion using circular mode helps saving CPU time. The problem is that with the generated code for a STM32MP157-DK2, I ...

Same problem here with STM32L462VETx and USB Virtual Port Com class. The warnings appeared when regenerating code after STM32CubeIDE update to Version: 1.15.0.

Hi, @JensH: with the same problem after the update, I followed your solution and worked for me as well.Could you shared with us why this problem appears after the update and how you came up with this concrete patch?Just willing to learn from this.Tha...
