STM32 MCUs Boards and hardware tools

Hello everyone. This trying to program some STM32F427 VIT6 through DFU but USB Windows does not recognize the Board (tried different cables and computers). I have also tried to program it using ST-Link Programmer, message "Revision ID: Unknown".Some help?

what is the minimum circuit i need for a STM32 to run it and debug via SWD? Is the attached schematic sufficient? For debugging I would connect my J4 to CN4 of a Nucleo board. Sorry for the trivial question, i don't have much experience with stm32

Where to get STM32H750-DK board schematic? Was it "removed from the board manual for user convenience"?

The revision history of the manual says that the schematic was removed in late 2021. Where I can download the "removed" documentation file? What was the purpose of removal?

What pins to power STM32F411CE with

I'm making a PCB for a project and am using the STM32F411CE (Otherwise known as the "Black Pill"). However, after spending many hours looking through the data sheet and searching online I'm still not 100% sure I understand how to power this board via...

STM32 programming and debugging without STLINK?

i want to make PLC using STM32.in PLC circuit there is no STLINK programmer still we can program and debug(simulation) PLC How can i do this?below delta PLC images. There is no separate debugger or programmer in pcb.​

ST-LINK forced update

Hello,We have CI/CD pipeline running in a build server with an ST-LINK attached to program an STM32 MCU. Suddenly the pipeline stopped working because of:ST-LINK firmware upgrade required. Please upgrade the ST-LINK firmware using the upgrade tool.Th...

Signal Noise on relay module

Hello to everybody,I have a problem I can't solve with an STM32 H7 board.I wrote a little app to command a solenoid valve (24V, 200 mA). It's very simple, I have two software buttons for opening and closing it, using a relay module.Testing it, everyt...

Board with the most capacity for GPIO_EXTI (external interrupts)

HelloI am planning to start a Hardware MIDI Control Surface design that incorporates a large quantity of rotary encoders, so I am searching for a prototype / evaluation board that has the most potential for GPIO_EXTI (external / attached interrupts)....
