CAN Shield Mask Question

Hi,

I would like to use the hardware mask feature on this shield and am a little confused how it works. I would like to know the following:

  1. Where do I place init_Mask? In the void(setup) routine?
  2. Where do I identify the ID of the message in the mask?
  3. How do I access the masked data? Do I just use the standard CAN receive data since the mask just lets the masked data through into the normal buffer?

If there is a good example could someone post it?

All help is greatly appreciated!!

Thank you.
