Apparently, you'll have to look at the schematic for the Due to figure out exactly which of the 6 pins is MISO, MOSI, etc.
You're right. Did that and found the SS pin, which is pin 10 (SS0 actually), and on the top right part of the schematic I can see an SPI chip(?) where the MISO, MOSI and SPCK pins are (I guess the SPCK is what I've seen on SPI shift register tutorials as SCK, or not?). The thing is that I don't know much about schematics and can't understand on which header these pins go. I can distinguish the headers in the schematic, but the only connection I can see with the above mentioned pins is to the mail processor chip, where they are the pins with numbers 108., 109 and 110 respectively. Can someone help me out by pointing out which headers I should plug my jumper wires in?
The schematic is here http://arduino.cc/en/uploads/Main/arduino-Due-schematic.pdf
