Hallo everyone,I tried to export the measured data of my project on a WeAct-3.0 STM32H723 board as an USB_OTG_HS stream to a Virtual COM Port on my Windows desktop. Unfortunately, I fail to get this operational, despite many trial and erro...

Hallo everyone,Since some time I struggle to get DMA access working on a STM32H723. I was pointed out this MCU is a complicated beast, but I would at least expect sensible, coherent documentation for it.When I look at page 683, I see:on next pag...

Hallo,I needed more performance for my project, so I replaced my STM32F401 Blackpill by a WeAct STM32H723VGT6 board. I adapted my HW to accomodate the different layout of the H723 board and modified my application where needed because differences in ...

Hallo Ascha.3,Thank you for the correction. I didn't check the result after my change of the USB Clock setting (to 50MHz), I assumed the automatic solver had found a way to create the requested value. After your reply I checked it; the solver has...

Hallo AScha.3,Thank you for your quick and useful response. I never thought about your reasoning, which makes sense. And I assume the debug cases I ended in the endless 'HardFault_Error' loop are caused by this.A related question: is it possible ...
