Connected with the microcontroller circuit diagram:
keil debugging variable values can not be viewed because the variables are not global variables ---
Solution:
Variable in the outer function as a global variable ----
result:
If you only want to view the current local variables within the function value can be used to call local stack segment call stack + Local
