Great explanation of an important topic. 4:30 Would it be sufficient to use a GetFunction such as int GetFlag(void){return flag} which is called by main while(Getflag() == 0) instead of using volatile int flag? I'm not sure if the compiler could remove even a function call for optimization.

It is so clear!! By the way, i want to buy your book but i want epub because i have an e-reader. Do you consider to deploy as epub on amazon?

Sorry. My publisher has no such plan yet.

good explanation but volatile keyword is such a BS that its meaning is ambiguity itself. In this demo, we should assume that it's compiler bug! Why optimize out a memory access when a) systick handler accesses the memory area b) they are advertising their product is a compiler for embedded system development. The compiler should know!

Do not agree that Volatile is BS but my exact thought was that systick handler is already there in startup code, why compiler not aware about this?
