STM32 MCUs Embedded software

Resolved! Is there any possibilities to produce nanosecond delay from STM32F4 Discovery ? because using HAL_Delay can only produce 1ms delay which is 500KHz

Will there any hardware issue for not working of USB OTG FS in STM32h743VIT.

I am using USB to communicate between two processors. Firstly it was working fine, but later during testing period it stopped working. The other Functionality of the controller seems to be fine. Is there any hardware checks to be done to ensure that ...

Why using cubemx to config STM32H743Zi-Nucleo ethernt project can not ping correctly

Posted on July 01, 2018 at 17:03Hi all: I use STM32H743zi-Nucleo, and use cubemx to config ethernet, using IAR and static ip address, after generate the code, but I can not ping the board. Dose anybody know where is wrong? The attachment is the...

Does STM32F746ZG, supports low level drivers for UART???

If I am making UART6, as HAL layer, it's working fine but if it configure it as LL api, it's giving garbage values.

How do I properly initialize the ethernet peripheral in CubeMX for the F7?

I'm new to embedded systems development and am trying to create a simple TCP client on my F769NI-DISCO board. I am depending on CubeMX to do most of the low level hardware initialization as my background is in higher level software engineering. I am ...

STM32Cube_FW_F7 can not setup USB HS properly on some devices

STM32F730 and STM32F722, might be more other variants updated usb hs otg register map, added ULPISEL bit in OTG_GUSBCFG register. However, it is not going to be set when choosing external hs phy in cubemx. The problem causes external phy not working ...
