Hi,
I have a problem.

I want to insert assembler code into C rutine in IAR compiler.
I prove with #asm and #noasm but no function.

How do I do?

Help me

You can do one of two things:

1) Use inline assembler, for example:

    void test()
    {
      asm("nop");
      asm("nop");
      asm("nop");
    }

Or, even better, write your routine in assembler and call it from C.
There is an entire chapter in the manual that covers this.

You can use the _OPC() instruction to insert op codes
directly to memory. 
Search for this instruction in the help of IAR. To
quickly know the instruction opcodes use the debug
mode and watch the program listing in assembler wich
will put line in C and assembler the next and so on.
Good luck!
