Detailed Description

This board is describes the STK541 that comes with Atmels ATAVRRZ541 Packet Sniffer Kit.

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

Intialization of the hardware timer T1 (16bit)

  • CS1[2:0] = 1 : Prescaler = 1
  • WGM1[3:0] = 0 : Mode = 4 : CTC operation

Timer is clocked at F_CPU, and TIMER_IRQ_vect is called every 65535 ticks.
