| I've just spent some time in front of the oscilloscope again, and tested with the SPI-function and found something interesting; the clocksignal (PIC-SCK) seem to be constant at 5V (apart from some noi ... | |

| I'll look into the level-shifter - the 5v are just for the prototype, later the whole circuit will run on a 3V battery anyway, so there it won't be a problem.
So for the SPI-Mode - the Atmel can us ... |

| Thanks for your fast reply! I didn't have a pull-up resistor there, but I tried it now (connecting a 4.7kOhm resistor between ATMEL-SO and 5V and measured the voltage between GND and SO), the pin real ... | |
