Help stopping a cog using a pushbutton

Paco

Hello everyone,
I am using the propeller chip to display some info on a LCD screen. I get data from sensors and am able to display some of it on the LCD. Here is my problem, I have a Menu screen displayed on the 4x20 LCD and when I push a button (pin 8) I create a new cog to run another object. I want to be able to run the new object in a new cog and then, whenever I push any one of 3 buttons (pin 9, 10, or 11), the cog should stop and return to the main menu object.

Here is the code I have to launch the new cog:

if ina[8] == 1
screen.cls
screen.str(string("Auto Mode", 13))
thedim := (cognew(dimmer.Main, @stack) + 1)

if ina[9] == 1 or ina[10] == 1 or ina[11] == 1
cogstop(thedim)


Will this work? I tried several ways and sometime it seems like it stops the cog originally running and keeps the new cog running. Any suggestions would be great, thanks in advance.

Read mpark's post.

A full copy of your code may be helpful here. It seems like a simple question, but it all depends on how you have your code setup. Also, putting code into [code] boxes would be nice, so we can see indention.

One easy way to possibly do what you are trying for, is if the same object is called for each of the three buttons (that's what it looks like in your above code), add a "stop" method that automatically gets called when a "start" method is called.

Either remove "+ 1" from this line

thedim := (cognew(dimmer.Main, @stack) + 1)
                                       ^^^

or add "- 1" to this line

cogstop(thedim)
              ^
