Hi Jan,
STD::cout Can’t see variables
Everything was fine after that , There was a situation where I had to uninstall and reinstall the operating system.
But I didn’t change anything.
I just felt that there is something strange on the screen where I selected the serial port of the teraterm.
This is what it looks like when I connect it;
This is how it shows the port when the NUCLEO is not connected;
Seems like this is causing a problem with the port is it seeing something else when the port is idle?
We don’t need to take a library review, I observe the same thing in the code in the screenshot I took.
