I expected to connect my PC to a nucleo STM32H743ZI2 board via a USB isolator (Linear technology) but failed. While, I can connect to the nucleo board directly without isolator and programme it. Beside, the PC can recognize the STLink from nucleo boa...
Hello,I look for information, what is the best layout for the SMPS, which is included in the STM32H745. One of my problems is, for a proper design, you must consider to have small loops in the switching path.For my base layout, I used the same struc...
Hi to everyone,I am an engineering student and I am doing a project using an STM32L476RG board with the Arduino IDE. My goal is to read four analog inputs from four vibration sensors attached on a surface and to detect the signals from an impact on t...
I just got a STM32F723 board to learn how to use USB model, and I found that when I use USB as FS host and connect a device, the register PCDET did not triger an interrupt while PENA is set, I'm wondering how can I get interrupt flag, is there any ...
Hello,I have a evaluation Board STM32L552E-EV, after working with J-LINK SEGGER I now I go back to the initial configuration with ST-LINK.Now I have this messageAfter I switched back to ST-LINK with ST-LinkReflash.exe. It's OKDo I need to do anything...
Hi all,I have a Nucelo-H7S3L8 board running the demo application. The project has 2 applications (boot, and application). The boot is supposed to jump to the application, which is located in the external MX25UM25645GXDI00 memory. However when debuggi...
how to use printf in stm32f429i-disc1?
I am using stm32u5g7vjt6 MCU and need to program the same using STLink v2 programmer using internal power (without using external power supply). What are the modifications I need to make in configurations for the same?
Hi,I am working with some custom boards for H7 and U5-series.The board schematics for STM32H735IG-DK and STM32U5A9-DISC shows both boards are using the same OCTO SPI but only the H7-board is using series resistors of 33 ohms for the all the data line...
Hello, I am following a few examples for bare metal firmware (without HAL or LL) to enable USART. I am using a NUCLEO-H745ZI-Q starting with an empty project. From the users manual I am gathering that the STLink MCU on the board provides a 25MHz (X1)...
