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...
