Is the heap used by redlib?

[muis]

I do not use any malloc() calls anywhere in my code, and also no semihosting (Redlib: None).

- Does this automaticly mean that I dont have to worry that my firmware has enough RAM left to have room for the heap space, since I dont use the heap? Or are there some functions (like strlen in string.h) that do make use of the heap behind the scenes?

For Redlib (None) I am pretty certain that you should be OK. But you can double check in the map file generated in the Debug/Release directory by the link step of your build.

You will currently end up with malloc if you build against Redlib (Nohost) or Redlib (Semihost) though.

Do remember that, even if you are not using the heap, your stack will still consume memory.
