Resolved! STEVAL-STWINKT1B - Can't recognize USB conection
Hi, I tried to connect my board to my computer trought USB but I can't recognize the board, it doesn't appear, I can't use the Programmer either. I downloaded different drivers, I used different cables but it doesn't work. What can I do? The BLE conn...
Resolved! Can I use the ST-LINK V3 of a Nucleo-144 to flash an external MCU?
My board is the NUCLEO-H743ZI2, I've looked in the manual but haven't found anything so far. Maybe I could remove jumper JP2 so the Nucleo's MCU stays powered down and then connect the CN2 connector (SWD) to the external MCU?Thanks!
STM32H755BIT3 Supply connection
你好 我正在与 STM32H755BIT3 一起做项目。我设计的电路板的现状是，用DC-DC 3.3V电源上电后，芯片很快发热严重，不出现短路就无法下载程序。我推测这是由于外围电路的设计。 有人可以帮忙找出问题所在吗？ 提前感谢大家的任何提示。 Translation: Hello I am working on a project with the STM32H755BIT3.The current situation of the board I designed is that after...
STM32H755 Nucleo – How to Use PA11, PC14, PC15 as GPIO Output?
Hello,In my project using the STM32H755 Nucleo development board, I need to use PA11, PC14, and PC15 pins as GPIO Output to drive relays. However, when I checked with a digital multimeter, I found that these pins cannot be driven to logic HIGH — they...
Resolved! ST_LINK can not connect to target
Hello, I've been trying everything for days to fix this error. They said to set the BOOT0 pin to GND. I followed these steps. I tried many solutions from YouTube videos and the STM32 website, as well as solutions from forums, but none of them worked....
Resolved! Nucleo H755 LED3 not turning on (PB14) in IPC Example
Hi everyone,I am working on a project with the STM32H755ZI-Q (Nucleo H755ZI-Q) board, and I am following this tutorial for Inter-Processor Communication (IPC) using OpenAMP: Link to tutorial.The setup involves two processors (M4 and M7). Here's the ...
Resolved! How to use multiplexing port.
Hi all.I'm using STM32H747I-DISCO bord.According to user manual, Pin No.1 in Pmod™ is connected to PA11/PA0.And Pin No.1 in STMod+ is also connected to PA11/PA0.Then can I use PA11 as USART1_CTS via Pmod™ Pin No.1, and PA0 as GPIO via STMod+ Pin No....
