Hi everyone,I'm working on decoding an SBUS signal, which uses an inverted normal UART protocol, supposedly at 100 kBd. However, I'm consistently encountering a HAL_ErrorCode 4 (which I believe indicates a framing error). The setup works fine when th...

HiI have a weird problem and do not understand where it could come from and thus do not know how to solve it. I am adding list entries to a list, and it seems to function correctly when I add them hardcoded. However, when attempting to add an entry r...

Hi Is there a way to sort of set a breakpoint to figure out which part of my code is messing with a specific memory address in STM32CubeIDE?I've got this dynamically allocated address that keeps getting changed by something else in my code, and I'm t...

Thank you, this works...Now, i have to find the problem :-). It seems that it is suddenly being changed at numerous locations in the code, but I dynamically allocated it and have not freed it. Any ideas?

I reinstalled STMCubeIDE and it is working again. The breakpoints could have been an idea so. Thank you all

... and do you have any insight into where this issue might have originated from suddenly?

It worked partially as the same problem still occurs at another location in the code... so it is not really 'the solution' yet. Any other ideas? What i did was: Project => Properties => C/C++ Build (Tree) => Settings => Tool Settings (Tab) => MCU GCC...
