Hi
When I compiled my old Program in Studio2, I get an out of memory error, even I “optimize for size” in “Preferences”
In the old BasicMicro IDE there was about 320 bytes free.
In the Studio -170
Is there a reason why Studio uses more Atom40 Memory ??

Can't be RAM you are talking about because 320 is more than the Atom/Nano has. So I am assuming you are talking about program memory.

A 490 byte difference from two versions that are over a year apart indicates either your old program was compiled for size (you can enable compiling for size in Studio preferences as well) or you are using some commands that had bug fixes. For example, ADin got about that much bigger to be compatible with all the new processors, it uses a table lookup system for determing which pins are A/D pins which added quite a bit of code but made it full proof.

Hi Nathan
Yes.. mistake I mean Program memory
and I speak about a Atom40.
Both the IDE 05.3.1.0 and the studio2, I have compiled for size.

MBasic PRO Compiler 5.3.1.0
….
Stack size recalculated to fit in BANK0
STACK = 15

Did nor use ADin.
About 500 byte different looks a bit much to me ..but O.K.

May seem like a lot but a lot changed in what amounts to nearly 2 years since 5.3 was released. Mainly all command arguments are now handled as 32bit values which added some more overhead as well. Also ADIN wasn't the only major change to commands. A large program that uses a lot of library commands could easily see a 500byte increase in size.
