Hello!
I have uVision that compiles fine with the C51 v7.03 compiler and the related package, but not complete with the 8.06. I used two different Keil installations. All files are in the same folder.
In the 8.06 I get linker errors like "object does not fit in to pdata page" and "0080H". This looks like the compiler was thinking the PDATA was only 128 bytes, but it is set to 256 bytes in the startup.a51. Any clue what's different in the newer Keil package?
Also there is a warning in 8.06 (which does not show in 7.03) "converting non-pointer to pointer" on this
ptr_xdata = sPtr_obj->Adresse;
while the vars are set like this:
uchar uc_set_obj( uchar pdata *ptr_Set) { uchar i; uchar xdata *ptr_xdata; struct stOBJADR code *sPtr_obj; sPtr_obj=&Obj[*ptr_Set]; . . . ptr_xdata = sPtr_obj->Adresse; }
The struct stOBJADR has a member "uint Adresse;"
I can see no wrong use of the pointers. I just want to be sure that the warning does not affect the code to not work correctly.
but in german we say:
No. We don't. You do. That, of course, is precisely the root of the problem. You confused yourself enormously by using such incoherent terminology
Ein Zeiger, der auf eine uint-Variable zeigt, ist vom Typ uint.
Nein, ganz sicher nicht. Ein solcher Zeiger ist vom Typ "Zeiger auf uint", oder auch "uint-Zeiger", wenn es gerade sehr eilig ist.
Wie sollte man diese Adresse denn sonst nennen???
Den Wert des Zeigers.
