Noob question

This is my first post to this forum so please go easy. Before you ask, I did spend about 10 minutes searching the forum and couldn't find anything.

I am putting a program together that requires the use of two of the same objects and I just want to make sure it is possible.

1)The object I am referring to is the MMBE object from the exchange.
2)The second object is the FullSerielDuplex.spin. This is used for the MMBE spin as well as the Xbee object.

I just want to know if I can run these without a problem of them stepping all over each other.

In the OBJ section I have:

          XB : "XBee_Object"  
    MMBE1   : "MMBE"
    MMBE2   : "MMBE"

in the pub section I have

MMBE1.start(18,19,2400)               'start(txPin, rxPin, baud)
    MMBE2.start(20,21,2400)               'start(txPin, rxPin, baud)

So again, to try to be as clear as I can, the MMBE object uses the FullSerielDuplex.spin object. XBee_Object also uses this object. Is this ok?

Yes, it's ok. Each instance of MMBE has its own private data area and the instances of FullDuplexSerial used by each MMBE and by XBee_Object are all distinct. All have their own buffers and variables. As you can imagine, each instance of FullDuplexSerial has to use a separate pair of I/O pins (as you're doing). You'll be using 4 cogs, 3 for each of the FullDuplexSerial instances and 1 for the main cog that runs everything else.

Thank you for you response! I wasn't completely sure.
