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...

STM32L081KZT6 Programmging

Hello! I've developed a pcb using the STM32L081KZT6I power it with a 3v3 volt supply and I'm trying to program it via JTAG-SWDSo I connected the SWCLK and SWDIO pins to pin 24 and 23 as shown in the datasheet, then I connected ground and 3v3 to their...
