Hi, According to mb1363 for the H755 Nucleo, in order to change from the default SMPS to internal LDO supply, to enable 480 MHz clock, I need to change C54/C58 from 100 nF to 2.2 uF. However it appears that there are no capacitors installed on my boa...

Hi,I have a project that was started on STM32F439 which I'm now migrating to STM32H755.In my original project I had a number of GPIO assignments for which the code generator was creating definitions in main.h, such as below: #define LCD_RST_Pin GPIO_...

Hi all, my first post here, being new to STM32..I have an STM32F439ZI Nucleo for which I have ADC1 nicely capturing data with TIM2 defining the sample rate and circular DMA.This was working well until I regenerated the code using the option to initia...

Hi @linuxfan , did you ever get a full understanding of DMA Access Mode, especially in the context of dual interleaved mode?Thanks

Thank you for confirming @Mike_ST , I will upload photos later today as requested.

I have this working, i.e. printf() and variable trace views in CubeIDE for STM32H755, but it wasn't exactly easy.Here's an explanation of how I made it work, including some things that didn't work when following standard advice that I found in this c...

If the number you are dividing by (the divisor) is a constant, or one that changes less frequently than the numerator, then normal practice is to calculate k=1/d (where d = your divisor), save that value, then use: y = x*k (= x/d) as your real-time s...
