Voltage Digital PIN

Hi, I have a Nucleo 144 STM32H743ZI2 and I try to convert 3.3v to 5v with level converter to send signal to a driver. I bought a Level Converter MH but when I measure the high voltage, marks 2.5V and in the low voltage 3.2v. I tried putting 3.3v from...

[Solved] Hi, I'm working with STM32F103C8T6. When I try to debug, it appers the window "No ST-LinkDetected! Please connect ST-Link and restart the debug session". I tried to modify debug configuration, but I can't debug my project. Can you help me?

Could Tech Support provide the solder profile for STM32L4R9ZIJ6 (UFBGA144) ?

Will there be different typesetting for ST 32-bit MCU body screen printing of the same model? Will there be different screen printing layouts due to different origin, packaging and environmental materials.

The typesetting of the second picture is inconsistent with that of the datesheet, does it exist? In addition, what is the meaning of E3 and E4, and what is the meaning of "X"

STM32F051C8: High current draw from VBAT when VDD is on

I have a minimal prototype circuit (breadboard actually) with this schematic: The firmware initializes a few peripherals (including the RTC) and enters an infinite loop calling __WFI(). Nothing else happens and nothing else outside the BOOT0 pulldown...

Detecting ST-Link V2-1 virtual COM port with C#?

Hello,I want to connect to the VCP of a Nucleoboard by a C# application. I don't want to iterate through all available COM ports on the system, so I'm searching a way to detect if one or more Nucleoboards are connected and connect to the correspondin...

How to program multiple STM32 MCUs over SWD (or otherwise) using one programming port

Hello nice people. I am supposed to develop a board that will have 2 STM MCUs (STM32F334 and STM32F01).Is it anyways possible to be able to program both MCUs (simultaneously or individually) using a single SWD port. I know how to do it using JTAG cha...
