Hi all,

I have the following line of code which I need to store in the IDATA memory.

char code *text_to_compare = "Tesing";

How can I achieve this please?
I found examples but they are all in assembly language.

 

char text_to_compare[] = "Testing";

 

char text_to_compare[] = "Testing";

Thanks for the reply. Is there a way to start from memory location 90hex ?

 

Any suggestions please?

 

We need to know which microcontroller and which compiler (IDE).

 

Thanks for the reply. I am using the 8051 with the C51 compiler.

 

Specify both brand names.

Or you can try:

char text_to_compare[] = "Testing" @ 0x0090;

char text_to_compare[] = "Testing" at 0x0090;

 

Unfortunately none of the above worked. If I remove the @0x0090 it is compiling normally and saving in IDATA, but not starting from 90H.
The micro-controller brand is Atmel and the compiler is Keil.
Thanks.

 

Try:

char text_to_compare[] = "Testing" _at_ 0x0090;

 

Unfortunately that did not work either.

Is it ok?

char *str_pt ;
str_pt = (char*) 0x0090;
str_pt[0] = 'T' ;
str_pt[1] = 'e' ;
str_pt[2] = 's' ;
str_pt[3] = 't' ;
str_pt[4] = '\0';

if you only want to declare it in idata:
char idata str_pt[] = "Test";
