Watch variables in Keil <not in scope>

setting volatile means that you are telling the compiler not to use optimization on that variable at all. What differences do you notice when you say that you cannot set every variable as volatile? you expect variables to change and you do not see that change?

I still have this problem, even at the level 0 optimization. I cannot very well set every variable as volatile, what can I do?

Not having the watch window REALLY makes debugging difficult.

Keil is really not perfect with debug time watch variables as the compiler optimizes their information when it needs to.

try to set the optimization to Level 0 in target settings
make your variables volatile to tell your compiler about a strict rule of not optimizing any kind of information regarding that variable.

This will help get your watch variables visible while stepping.
