Posted on January 29, 2009 at 08:32Hi,
I have a question about theory of pointer.
I use ST7Lite19F and 29F.
I use old compiler Hiware.
I have a problem and I don't understand if it is a limit of microcontroller or a compiler problem!
If I write:
VarOne[MY_CONST] = VarTwo[MY_CONST] ;
with:
static unsigned int VarOne[2],VarTwo[2];
#define MY_CONST 1
This work!!!
But if I write:
static unsigned char n;
and re-write:
VarOne[n] = VarTwo[MY_CONST] ;
I have this error:
''D:\Documents and Settings\Users\Desktop\V2.1\Build\project.prm'': ERROR L2410: Unresolved external __R_Z (imported from main.o)
''D:\Documents and Settings\Users\Desktop\V2.1\Build\project.map'': INFORMATION L2203: Listing of link process to D:\Documents and Settings\Users\Desktop\V2.1\Build\project.map
ERROR L2104: Linking failed.Question:
this is a problem of addressing mode or problem of compiler?
It's pointer at pointer at char! It's unsupported from ST7LITE19/29F?
Thanks
