Using 'Real' 1 Bit Boolean Variable For Arduino Memory Efficiency
Показать описание
Arduino use 1 byte of memory space for each Boolean variable. Do you know that?
So for 8 booleans, 8 bytes of memory space, instead of only one byte! You can be careless about this but when you approach to the end of the medium/big size project sometimes we really need few bytes more and we go for hunting some bytes in the project. This is really happend to me, that’s why I had to find a solution to gain a little bit more memory space by hunting fat booleans who consumes 1 byte (8 bits)
With the macro, I’ve written I compress them in a space that they worth. So 8 booleans take 1 byte (8 bit) only! Means; %85 memory saving.
