Hi,I'll need one NUCLEO-H7A3ZI-Q in about a month. But next week the Trump administration takes over here in the USA and he promised to impose tariffs on Chinese products. I remember last time he was in office. Almost everything electronics got an ex...

Hi all,I used touchGFX before with a STM32F746-DISCO board and that worked fine to get started but now I'm looking to make a custom board with an STM32H7A3 MCU and I see nothing in the touchGFX designer for this MCU. There is an STM32H7B3 DISCO board...

Hi,I' was looking at this board thinking it is one of the newer ones. I think of the STM32F7 as the older and STM32H7 as the newer ones. The reason I'm asking is because I want a STM32H7 kit with an (micro) SD socket and an audio codec. This kit see...

This is for: cubeIDE and the built-in version of cubeMX and STM32F746 disco board.The autogenerated code from cubeMX generates this Error_Handler() function for every (potential) error from the HAL functions. Every peripheral gets the same function c...

Hi all,Reading page 400 of RM0399 (Reference manual STM32H745/755 and STM32H747/757). It talks about how to allocate peripherals for each core. But I don't understand. I can't seem to find the PERxEN bit in either RCC_DnxxxxENR or RCC_C1_DnxxxxENR re...

That's gonna take time but thanks for asking.

I found how to remove the shortcut folders. when I was adding the folders to the CM7 core project. It looks like I added them as "/DiscoBaseEmpty_CM4/Core/Src" and "/DiscoBaseEmpty_CM4/Core/Startup" to the source locations in the project properties (...

It is not good practice. If this was a board to be assembled by a CM (contract manufacturer) it would have solder paste applied by a stencil. The stencil has a thickness depending on the components on your board. Not a lot of paste goes onto the pads...

Hi,I didn't read all the replies I just did a text search for vias and pads and didn't see anyone pointing out that there are vias in pads (MCU, ULN2003 GND pin and caps). That's something to avoid unless you're very very tight for space. Just draw a...
