Running STM32H7 at 1.8V with USB High speed ULPI PHY USB3310

Hello all, I'm building a system that I'd like to run at 1.8V with an STM32H7 and USB high speed PHY.I have a few questions, so I'll just jump right in:1) Will the STM32H7 core run at 400MHz when powered by VDD=1.8V? Some MCUs can't run as fast ...

STM32F1 DMA+GPIO Issue?

I need to transfer parallel data via GPIO and DMA. The microprocessor I use is STM32F103C8I need to transfer some memory data to GPIO quickly. I've written an init code using STM32F103 and the HAL library. But DMA doesn't work. At the end of the proc...

Does the stm32h743i_eval.h work also for STM32H753i Eval boards ?

I have problems to get the example code running, few functions aren't known. I changed them to HAL-functions which were written (nearly) the same. But the Code fails just in the beginning. At the moment I try to erase the on-board external flash. Is ...

are there some tutorials about STMCUBE MX ?

FreeRTOS USB Host example

I need a STM32F411 DISCO USB Host example using FreeRTOS.My project is based on STM32F401. I don't have target hardware yet & have survived with a NUCLEO 401 and linking wire. That won't be good enough for USB.Nearest is a STM32F411 DISCO but my rush...

Can't connect to COM Port

Hi,I implemented a composite device program for my mcu (STM32F407IG) .Everything is working fine and the mcu get recognized as cdc+msc.Somehow it won't connect to the vcp when i am using a terminal program like HTerm to send data to vcp.Anyone have e...
