How to control a 5V output pin on STM32 Nucleo L4R5ZI remotely through a connected PC?
I have an STM32 Nucleo L4R5ZI, which is connected to a PC. The Nucleo is located in a place where I don't have direct access to it, so I can only control it through the connected PC.
I need to stop the 5V output from one of its pins for 10 seconds, by any means necessary. I'm okay with restarting or shutting down the Nucleo if needed. However, I'm unsure how to achieve this. I've already attempted to cut power to the USB from the OS, but that didn’t work.
I’m limited to making changes either in the code or the OS; I can't physically modify the Nucleo. How can I do this?
