B4R Question Advice for memory allocation on a Arduino MEGA2560

[tigrot]

After compiling my sketch I get this message:

Lo sketch usa 87040 byte (34%) dello spazio disponibile per i programmi. Il massimo è 253952 byte.
Le variabili globali usano 4870 byte (59%) di memoria dinamica, lasciando altri 3322 byte liberi per le variabili locali. Il massimo è 8192 byte.

This means that my variables in Global are 4870 bytes, can the rest of the RAM be allocated for #StackBufferSize: ?
Thank you for your time!

Not all of it. Leave some space for the built-in stack.

Thank you, nothing for heap?

B4R doesn't use dynamic allocation so the heap isn't expected to grow. It is possible that some libraries will make a few allocations.
Almost everything is done using the extra stack buffer or in the standard stack.

Will leave 1000 bytes free. Thank you!
