Hi All

I'm using Keil uvision4 C51 (AT89S52) (256bytes of Ram)

i making a code that interfaces many devices but after merging the codes

the Compiler don't generate o/p file and says

*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE (x 15 times)

and it appeared (for 15 subroutine)

so what the solution for this problem?

i can't use External Ram!! (all the Pines Used and the Rom Size is ~ Full)
i tried to use AT89C51RD2 Or AT89C51RC but the same problem appeared
so i Changed the Memory Model From (Small variables in DATA) to (Large variables in XData) it worked but the simulation is not working (using ISIS)

so if there is another Type of controller that support C51 Code and have the same Structure as 8051 Controller Let me know.

i will upload the M51 File To See The Stack States

Thanks In Advance

if 4kb is not enough for your appication then you may use other controller that has more ram than you are using now..

I suppose technically you might have to get their permission.
Of course you could post in on a file sharing site,
then only you would get in trouble

To be practical, code at this level is pretty standard stuff,
would anyone really care ?
