Resolved! Clarification on ST-LINK/V2 VTref (VAPP) Pin Behavior
Dear STMicroelectronics Support Team, I am working with two ST-LINK/V2 debuggers and have observed a difference in the VTref (VAPP) signal location on the 20-pin connector. I would like to understand whether this is expected behavior. Details of ...
STM32U5G9J-DK1: Interfacing a 3.3 V I2C via 3.3 V-to-1.8 V level shifter
Hello all, I want to connect a 3.3 V I2C based keypad with STM32U5G9J-DK1 via a carrier board on which the STM32 board sits via expansion connectors CN9 and CN10 present on it. I am using pins PG13, PG14, and PG9 for my I2C SDA, I2C SCL, and INTERRUP...
Pin contact to CN11 / CN12 of Nucleo boards
Dear people, I use these little square pins and headers (see image), to obtain access to the contacts of CN11 / CN12 of Nucleo Boards, e.g. H723ZG, or F756ZG?. However these are impractical, because movement or vibration might lead to interruptions...
Resolved! No SWD target connection with STM32F103 on custom PCB
Dear all,I'm unable to connect via SWD to my STM32F103C8T6. What ever I try I get no target found with STM32CubeProgrammer or ST-LINK Utility (I have tried all combinations at slow and high speeds). - device is virgin- BOOT0 is low- NRST unconnected ...
Resolved! Failed to start GDB server when debugging STM32F103C8T6
Hello everyone, I’m facing an issue while trying to debug my project custom_for_stm32f103c8t6 in STM32CubeIDE. When I launch the debug session, I get the following error message: Error in final launch sequence:Failed to start GDB server What I’ve t...
Resolved! How to interface or use STM32H563ZIT6 USB Host
Hi, I tried to configure the USB Host for a project, but it’s difficult to configure, and I am not finding any online support available for the STM32H5 series controller.My requirement: I configured PB4 as an output, which is connected to a green LED...
Resolved! NUCLEO-F103RB HSE Won't Start
I have a NUCLEO-F103RB (MB1136 rev C05). My goal is to remove the ST-LINK and power via a hat supplying 3.3v. For the 3.3v I have: Moved JP5 to pins 2-3.Checked JP1 is removed.Removed SB2 zero ohm resistor.Removed SB12 zero ohm resistor.Verified my s...
SPI problem on STM32H7
Hello, I’m having a problem with a board I’m developing based on the STM32H747BIT6. The issue is related to SPI communication. When I connect any device to the SPI bus, the signal level drops from 3.3 V to around 1.5 V. I have tested different SPI pe...
Resolved! stm32n6570-dk sd_sel pin not triggering / VENC_SDCard example code
Hi all, I have a small issue with the STM32N6570-DK board and the VENC_SDCard example code. The PN12 pin has a voltage of 0V (card inserted) or 1.80V (no card inserted); on the MCU side, the GPION data register (IDR) always shows a logic 0 in both si...
STM32F4DISCOVERY DAC PA4/PA5 not reaching true 0V (shows ~0.045–0.05V)
Hello ST Community,My name is Gorakhnath. I am currently pursuing M.Tech (Power Electronics and Drives) at NIT Kurukshetra. I am using the STM32F4DISCOVERY (STM32F407VGT) board and I need stable DAC outputs for my hardware application.What I need (re...
