Propeller BOE-Bot

Nishi .

Hi I've been working with my BOE-Bot for a while and decided to experiment with propeller by upgrading the Board Of Education to a Propeller Robot Control Board.

I downloaded the 'Spin Stamp Code for the Boe-Bot' @ http://obex.parallax.com/objects/155/

but when running 'ServosP13CcwP12Cw.spin'

''Robotics with the Boe-Bot - ServosP13CcwP12Cw.spin
''Run the servo connected to P13 at full speed counterclockwise
''and the servo connected to P12 at full speed clockwise

CON
                                       
  _clkmode        = xtal1 + pll8x
  _xinfreq        = 10_000_000

VAR

  long Pause, Pulsout
  
OBJ
   
  Debug: "FullDuplexSerialPlus"
  
PUB ServosP13CcwP12Cw     

  Debug.start(31, 30, 0, 9600)

  Pause := clkfreq/1_000
  Pulsout := clkfreq/500_000 
                                                          
  dira[noparse][[/noparse]12..13]~~
  outa[noparse][[/noparse]12..13]~

  Debug.str(string("Program Running!"))

  repeat
    outa[noparse][[/noparse]13]~~ 
    waitcnt(Pulsout * 850 + cnt)
    outa[noparse][[/noparse]13]~   
    outa[noparse][[/noparse]12]~~ 
    waitcnt(Pulsout * 650 + cnt)
    outa[noparse][[/noparse]12]~        
    waitcnt(Pause * 20 + cnt)

'********************************************************************************************

' Robotics with the Boe-Bot - ServosP13CcwP12Cw.bs2
' Run the servo connected to P13 at full speed counterclockwise

' {$STAMP BS2}

'DEBUG "Program Running!"

'DO
'PULSOUT 13, 850
'PULSOUT 12, 650
'PAUSE 20
'LOOP

...the right wheel goes Counter Clockwise and the left wheel goes Counter Clockwise (bare in mind Ive been using 850,650 2ith BS2)

I try

  waitcnt(Pulsout * 750 + cnt)
    outa[noparse][[/noparse]13]~   
    outa[noparse][[/noparse]12]~~ 
    waitcnt(Pulsout * 750 + cnt)

But the right wheel goes Counter Clockwise and the left wheel goes Counter Clockwise

I try with 650,850 same result?


am I missing something obvious?
