Ok, let's have a litte self talk... 
 
Where spi-devices are connected on a special hardware is highly hardware 
dependand. So it does make sense to not define interconnections between cpu 
und periphal directly. If you use an example application then there should 
be a call  
NutRegisterSpiDevice(NUTDEVICE * dev, NUTSPIBUS * bus, int cs); 
that connects the hardware. 
 
So I'll modify my contributed examples for 7-Segment LED driver and others 
accordingly.
