STM32 MCUs Boards and hardware tools

Where is the exact definition/derivation of the Vrefint (1.23 V) of STM32F302x MCU?

Hello,according the datasheet for "STM32F302x6 STM32F302x8" -> "6.3.4 Embedded reference voltage" there is the definition of Vrefint as 1.23 V. But how exactly is it generated / derivated?I also checked the advanced Arm®-based 32-bit MCUs - Reference...

Am working on NUCLEO STM32F401RE , so after debugging the code, am facing this issue. Please advise for this, so i can work speedy. Target no device found Error in initializing ST-LINK device. Reason: No device found on target.

STM32L452RET6 Question

Hi all,I am using the STM32L452RET6 On my board and i have 2 quiestion regarding it:1) VDD12 Net - how to set my hardware when i am not using external DC/DC? floating? GND? just a cap? if so what size?2) when entering boot mode and going over the i/o...

I'm using STLINK-V3SET debugger. IDE is CooCox. MCU is STM32F405ZGT6. As I try to launch a debug session, the stages "flash erase, program and verify" are completed and the debug session aborts instead of allowing to run the code. Why?

What changes need to done in migrating from SWD to JTAG debugging on STM32H745I-DISCO?

I am using STM32H745I-DISCO board and STM32CubeIDE 1.8.0. I am presently using on board ST-Link in SWD to program and debug the MCU. Now I want to use JTAG debugging using J-Link.What changes need to be done to make my project compatible to JTAG debu...

How to protect GPIO input from voltages greather than 3.3V/5V being applied there?

Hi, I'm using the stm32F207Z mcu for input/outputs digital processing. Mcu will also handle the Ethernet communications. Our application will read logic levels from GPIO pins configured as inputs, but it is also able to write on other GPIO port confi...

STM32 Boards and USB Host issue

Hi,I'm trying to make a simple USB host for MSC devices. I'm working with a STM32F429 NUCLEO-F429ZI board and a STM32F407 STM32F407G-DISC1 boards.The matter is that both boards have USB power switches wih oppostie logic. That is, the Nucleo boards ha...
