And these steps do not execute in a single cycle like a simple store into RAM does. Think about it: To write a single bit of flash, you have to erase a whole block of data an then rewrite the whole thing with the modified data. The scope of a certain variable matters only to the compiler, at the machine code level nobody prevents you from reading a local variable outside of a function (as long as your controller doesn't have some fancy features to protect memory areas from being accessed).Īnd global variables are stored in Flash. Static variables are stored in RAM, just like your global variables. ![]() Static vars are definitely not stored on the heap, since this is only for variables allocated during run time (and static vars are allocated during compile time). The following answer is based on my experience looking at mapfiles, if I'm wrong about sth.
