SPI clock is not clocking!

Hi everyone, i'm trying to read some data from an accelerator and for this purpose using SPI. I'm using NUCLEO-F401RE board. So after enabling SPI, clock pin goes HIGH as i want (CPOL=1) but when i send data CLK stays as HIGH until i disable SPI, mea...

How does USB FS DFU work to make firmware updates?

Hello I have two cards, the first is a STM32F746 Discovery and the second is a STM32L475 Discovery.I have to use USB FS to do the firmware updates using the DFU class in USB_Device in CubeMx.I have all tried to update the cards with the DfuSe Demo so...

Is the assembly language necessary for working with STM32 ?

STM with RDM DMX

Is there anyone who worked on RDMDMX with STM32 Controller?

I am using STM32F411VET6 MCU. I want to get into the DFU mode by using BOOT0 and BOOT1 pins. But MCU is not getting into the DFU mode.Please help refarding this
