Thread: creating delay

im pretty sure there is a way

#include <windows.h>
sleep(/*number of ms*/);

if that doesnt work try looking for it(the sleep thing) on msdn

>How many processor cycles is this delay?
It will depend on what i is. Take a look at the generated assembly. For example, this is what I get with an int i.

Code:

stmt level    source

   1          void main(void)
   2          {
   3   1          int i;
   4   1          for(i = 0; i < 16; ++i)
   5   1          {
   6   2          }
   7   1      }

             ; FUNCTION main (BEGIN)
                                           ; SOURCE LINE # 1
                                           ; SOURCE LINE # 2
                                           ; SOURCE LINE # 4
;---- Variable 'i' assigned to Register 'R6/R7' ----
0000 E4            CLR     A
0001 FF            MOV     R7,A
0002 FE            MOV     R6,A
0003         ?C0001:
                                           ; SOURCE LINE # 5
                                           ; SOURCE LINE # 6
0003 0F            INC     R7
0004 BF0001        CJNE    R7,#00H,?C0005
0007 0E            INC     R6
0008         ?C0005:
0008 EF            MOV     A,R7
0009 6410          XRL     A,#010H
000B 4E            ORL     A,R6
000C 70F5          JNZ     ?C0001
                                           ; SOURCE LINE # 7
000E         ?C0004:
000E 22            RET     
             ; FUNCTION main (END)

Now comes the fun of looking up the instruction cycle times.

>Is there a more efficient way to create a delay in my embedded system?
Timer interrupts come to mind. You might find some useful information here.
