im not sure if im referencing the cogstop correctly. when i press the pushbutton it stops the green led. im guessing that it is stopping the cog that contains the command "cogstop" instead of the red led , the one im trying to reference.what am i doing wrong?

CON
        _clkmode = xtal1 + pll16x                                               'Standard clock mode * crystal frequency = 80 MHz
        _xinfreq = 5_000_000
VAR
  long stack[100]
pub main
dira[8]~~
dira[2]~
cognew (led,@stack)
  
repeat
     !outa[8]                          'flash green led
     waitcnt(clkfreq/2+cnt)
      if ina[2]==0                     'if button is pushed stop red led
        cogstop (led) 
      
 
pub led
dira[9]~~
repeat
   !outa[9]                              'flash red led
    waitcnt(clkfreq/2+cnt)

That should fix it. Making c = to the cog called allows you sotp the cog with cogstop(c). Hope this helps!

cogstop works on cog specified by it's cogid so passing it the "led" function as it's parameter is not right.
Where does one get a cogs ID from? Well cognew returns the cog ID of the cog it started. So use something like

redCogId = cognew (led, @stack);

then use

cogstop(redCogId);

Check the manual for details of how this all works.
