Detailed Description

AT86RF230 adapter board wired to STK500 with ATtiny26.

The wiring of the radio and the ATmega is shown below:

     AVR       RF230
     ---       -----
     PB0  -->  MOSI
     PB1  <--  MISO
     PB2  -->  SCK
     PB3  -->  SS
     PB4  -->  RSTN
     PB5  -->  SLPTR
     PB6  <--  IRQ (INT0)
               MCLK (NC)
     PB7  -->  (reset)

    PA0:3 <--  KEYS
    PA4:7 -->  LED
