Access variables in a C program from inline asm

[rasmusnygaard]

How do I access variables in a C program from inline asm. Now I access the variable by writing direct to the RAMadress from asm.

What do I write instead of XXX when I want to increment the testvar?

void main()

{

   char testvar;

   asm

   {

      inc XXX

   }

}

Best regards

Thanks - it works. I did not even try this straight forward method, because of my experience from other compilers.

Hello

I assume you are using CodeWarriot for HC08. AM I right?

You just use the variable name as defined.

void foo(void)
{
   char testvar;
 
   __asm
   {
      inc  testvar
   }
}
