#asm help
PostPosted: Mon Aug 24, 2009 1:36 am     Reply with quote
Don't really know much about assembly so could some one explain this piece of code to me.

retardo is an int. Are the pieces of code the same?

Code:
         #asm
 bucle: #endasm
        delay_cycles(delay_multiple-3);
        #asm
        decfsz &retardo,f
        goto bucle
        #endasm


Code:
 bucle:   
        delay_cycles(delay_multiple-3);
           #asm
            decfsz &retardo,f
           #endasm
        goto bucle


when will the code get out of the loop?

Thanks

The loop is exited when the contents of Retardo = 0
