C example under uClinux

[Altera_Forum]

Hallo 

 I want to write a C program. This C program should use a led on my NIOS II Evaluation Kit, Cyclone Edition. I think i can use the command outl but i believe i must use the include header asm/io.  My first question. Is that correct? But i have not this header. So what can i do. Have anyone an idea? Have anyone this header?  Thanks

you can copy & paste the routine from asm/io

#define inl(addr)  

({   unsigned int __res;  __asm__ __volatile__(   "ldwio %0, 0(%1)"   : "=r"(__res)   : "r" (addr));   __res;  })  //----------------------------------------------------------------------- # define inb(addr)  ({   unsigned int __res;  __asm__ __volatile__(   "ldbio %0, 0(%1)"   : "=r"(__res)   : "r" (addr));   __res;  })  //----------------------------------------------------------------------- # define outl(b,addr)  ({   __asm__ __volatile__(   "stwio %0, 0(%1)"   : : "r"(http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif , "r" (addr));  })  //----------------------------------------------------------------------- # define outw(b,addr)  ({   __asm__ __volatile__(   "sthio %0, 0(%1)"   : : "r"(http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif , "r" (addr));  })  //----------------------------------------------------------------------- # define outb(b,addr)  ({   __asm__ __volatile__(   "stbio %0, 0(%1)"   : : "r"(http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif , "r" (addr));  })
