Questions:

• b_rachid85@yahoo.fr asks:

  I'd like to use the PIC with an RF transceiver (CC2420 from chipcon), If I use the IEEE802.15.4 MAC layer, do you know any resources that can help writing my application?
  Can I just program the PIC without using this MAC (then of course it will not be IEEE802.15.4 compliant )
