Package ckbot :: Module wixeltdma :: Class Hub

Class Hub


Concrete MultiProtocol subclass for Wixel TDMA connections

TYPICAL USAGE:
  H = Hub()
  P1 = Dynamixel.Protocol( Dynamixel.Bus( 
      port = H.getNewNodeConnection( tid1 )
      ))
  H.addSubProtocol( P1 )
  P2 = Dynamixel.Protocol( Dynamixel.Bus( 
      port = H.getNewNodeConnection( tid2 )
      ))
  H.addSubProtocol( P2 )
  # start loop with H.update() called
