Hi All,I have a situation where I would like to allow STM32H7 based embedded web server users to update the password which is originally hardcoded in the code using const keyword. Which effectively means password is placed in internal flash memory o...

Using STM32F767 Nucleo board and STMCubeIDE I am trying to transmit SPI data with data size of 8bit per transaction while I have setup my SPI2 in Full Duplex mode.Problem is that although I am able to transmit from MCU and receive on slave side the d...

Hi,I am using stm32f779 RTC upto subseconds granularity that is using SSR register value for giving upto milliseconds level of time output .The scenario is such that there is external time source ( network clock) to which I synchronise RTC by updat...

I am using STM32F779 and trying to use its RTC sub second functionality. Also, using a network time to synchronize with RTC. The issue I am having is as follows along with what I have already tried:In order to advance SSR register to synchronize wit...

We came across a situation where an application code which is working for STM32H753 revision Y when moved to same MCU's revision V does not even go to the main.cpp.Sometimes if it manages to go to main.cpp it writes to I2C1 some values consistently ...

Thanks for response. Can you please share any example code which describes how to do it?

There are major differences between running an application using the C-SPY debugger, compared to running stand alone.When debugging the application with the C-SPY debugger, a number of SFRs are set by:the flash loader source code.the mac file used by...

Thanks very much KnarfB that resolved problem.

@Community member thanks for your response. Even if the value of SSR is larger than PREDIVS it is valid?As soon as I get returned from update and print that value rather than 3 digits output it shows 6 digits for milliseconds (that only happens str...

If you look at the last section of the STM32F7 Reference Manual RTC synchronization that tells you about how to advance or delay adding into SSR using SUB bits of SHIFTR. Let me know if you need any more help.
