Help! strange problem with zero ram? or something else
PostPosted: Tue Mar 25, 2003 11:24 am     Reply with quote

Hello,

I seem to be encountering a strange phenomenon. A while back we had added the #zero_ram directive into one of our projects. Now we have removed it but the compiler is still burning up memory by performing a CLRF instruction on every ram location (or so it seems)

I have pasted here the section of the LST file that contains the main program. It seems that this ram initialization occurs before executing anything else in the main program.

Any help would be greatly appreciated as we're currently trying to optimize our code and free up some ROM space. I've searched my included files and there are no other instances of #zero_ram anywhere... could there be something else that is causing this phenomenon?

Thanks

Brent

Re: Help! strange problem with zero ram? or something else
PostPosted: Tue Mar 25, 2003 1:24 pm     Reply with quote

:=the compiler is still burning up memory by performing a CLRF instruction on every ram location (or so it seems)

The way variables are declared in C can affect this. Obviously int x=0; will get zeroed. Global and static might get it automatically. Since the areas are big I would look at any buffers you have created. I don't see huge blocks of CLRFs in my object code but I never asked why.

Thanks for the reply Barry, I did also get a reply from CCS themselves saying:

Variables declared like this:
int x = 0;

Or like this:

static int x;

Will get the CLRF in main().

So considering i had a number of variables declared static and a 512 byte buffer declared static it is no wonder I received so many in my code. It's all better now Smile
