  Jeff,
  
  to post samples of your code, paste your code between these two tags, except remove ALL the blank spaces I've inserted inside the brackets:
  
  [noparse][[/noparse] code ]
  
  [noparse][[/noparse] / code ]
  
  
  
  

  
  That way your code
    will look like this
      and all of its indentation
        will be preserved
  
  
  

  
  
  
  You might want to elaborate on exactly what you're trying to do with the various pins, etc. Frankly, I can't understand what you're trying to achieve.

  If I understand you right:
  
  Define a variable old_in and do
  
  
  
  

  if ina[noparse][[/noparse] 22 ] & !old_in
    right
   
  if ina[noparse][[/noparse] 23 ]
    left
   
  old_in := ina[noparse][[/noparse] 22 ]

  I have two input's, (22 and 23) I want one as, Retriggerable One Shot, the other one as A on off switch. How do I go about adding the Retriggerable One Shot. The input on pin22 is toggling. All I am looking for the program to do is, When input pin22
  is toggling, the led1 stays on and run's for the toggling time...
  
  
  
  
  
  
  
  
  

  
  
  
  
  
  
  con 
  
   _clkmode = xtal1 + pll16x
   _xinfreq = 0_500_000
   
  pub Kid
  
  'dira[noparse][[/noparse]0..19]~~
  
  repeat
  
      if ina [noparse][[/noparse]22] ((((the input one pin22, need's to be  Retriggerabel One Shot, how does the progarm have to look?))))))
        led1
      if ina [noparse][[/noparse]23]
         led2
    
    
            
  pub led1
          dira[noparse][[/noparse]0..19] := %11111111111111111111
          outa[noparse][[/noparse]0..19] := %00000000000000000000
          waitcnt(clkfreq/4 + cnt)
          outa[noparse][[/noparse]0..19] := %00000000000000000000

  This is working but I need more time on the Retriggerable one shot. how do I add more time.
  
  
  
  
  
  
  
  

  
  
  con 
  
   _clkmode = xtal1 + pll16x
   _xinfreq = 0_500_000
   
  var long old_in  
  pub Kid
  'dira[noparse][[/noparse]0..19]~~
  
  repeat
  
      if ina [noparse][[/noparse]22] & !old_in '((((the input one pin22, Was to be Retriggerable One Shot, how does the progarm have to program?))))))
        right
      if ina [noparse][[/noparse]23]
           left
    
  old_in := ina[noparse][[/noparse]22]

  Download the Propeller Education Kit Lab Manual for free, see the link for "Full Text":

  Inside the manual there is a section on Input/Output basics and Timing. I think it will teach you everything you need to know about making your pins do whatever you want.
  
  Hope that helps.
