The Packet Sniffer Kit STK541 is a carrier board, which fits on top of a STK500 and is used for the radio controller board family. The transceiver wiring fits the common RCBs. The wiring of the radio and the ATmega is shown below:
AVR RF230
--- -----
PB4 --> SLPTR
P?? <-- MCLK
PD4 <-- IRQ (ICP1)
PB5 --> RSTN
PB0 --> SS
PB2 --> MOSI
PB3 <-- MISO
PB1 --> SCK
The STK541 has no LEDS and Keys, so we define the ressources
from the RCB230 here.
KEY: PE5
LEDS: PE2:PE4
DBG: PD0 - connector X20:2 (ground X20:1)
Fuses/Locks:
LF: 0xe2 - 8MHz internal RC Osc.
HF: 0x11 - without boot loader
HF: 0x10 - with boot loader
EF: 0xff
LOCK: 0xef - protection of boot section
Bootloader:
Start at byte=0x1e000, address=0xf000, size = 4096 instructions/ 8192 bytes
