How to get variable from another cog

Don M

Lets say I have some methods running in a cog. In that cog I have a byte variable called poll.

Now in my main cog I want to get the value of of "poll". Is there a simple way of doing this? Do I use the @ sign somehow?

Thanks.

Add the method below to the child object.

PUB GetPoll

  result := poll

The parent object calls this each time it wants to know the value of poll.

Alternatively you could return the address of poll to the parent object.

PUB GetPollAddress

  result := @poll

In this case the parent object just needs to call this method once:

pollAddress := GetPollAddress

When the parent object wants to know what the value of poll is it uses:

long[pollAddress]

Let's say the parent wants to take some action when poll equals two. It would use code like this:

  if long[pollAddress] == 2
    ' do stuff when poll equals 2
