Detailed Description

Definition 2.4G Module from In-Circquit with AT86RF230 and Atmega1281 (V1.0).

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

  ATmega1281    AT86RF230
  ----------    ---------
     PB1    --> SCK
     PB2    <-- MOSI
     PB3    --> MISO
 PB0/PB4    --> SEL        (you need to drive both pins)
     PB5    --> SLP_TR
     PB6    --> TRX_RESET
INT4/PE4    --> IRQ
    XTAL2   <-- CLKM

    PD0     --> KEY Interface
    PD6:7   --> LED Interface

    Fuses:
      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

Build Options

ict230 : Incirquit Module

Define Documentation

#define CUSTOM_RESET_TIME_MS (10)

additional delay needed by hardware

#define DDR_SPI (DDRB)

DDR register for SPI port

#define DDR_TRX_RESET DDRB

DDR register for RESET pin

#define DDR_TRX_SLPTR DDRB

PORT register for SLP_TR pin

#define DI_TRX_IRQ ( ) {EIMSK &= (~(TRX_IRQ));}

rising edge triggers INT4 disable TRX interrupt

#define EI_TRX_IRQ ( ) {EIMSK |= (TRX_IRQ);}

enable TRX interrupt

#define MASK_TRX_RESET (_BV(PB6))

PIN mask for RESET pin

#define MASK_TRX_SLPTR (_BV(PB5))

PIN mask for SLP_TR pin

#define PORT_SPI (PORTB)

PORT register for SPI port

#define PORT_TRX_RESET PORTB

PORT register for RESET pin

#define PORT_TRX_SLPTR PORTB

DDR register for SLP_TR pin

#define RADIO_TYPE (RADIO_AT86RF230)

used radiio (see const.h)

#define SPI_DATA_REG SPDR

abstraction for SPI data register

#define SPI_MISO _BV(PB3)

PIN mask for MISO pin

#define SPI_MOSI _BV(PB2)

PIN mask for MOSI pin

#define SPI_SCK _BV(PB1)

PIN mask for SCK pin

#define SPI_SELN_HIGH ( ) PORT_SPI |= SPI_SS; SREG = sreg

set SS line to high level

#define SPI_SELN_LOW ( ) uint8_t sreg = SREG; cli(); PORT_SPI &=~SPI_SS

set SS line to low level

#define SPI_SS _BV(PB4)

PIN mask for SS pin

#define SPI_WAITFOR ( ) do { while((SPSR & _BV(SPIF)) == 0);} while(0)

wait until SPI transfer is ready

#define TIMER_INIT ( )

Value:

do{ \
        TCCR1B |= (_BV(CS11) | _BV(WGM12)); \
        TIMSK1 |= _BV(OCIE1A); \
        OCR1A = 1000; \
    }while(0)

Initialisation of TIMER1 (16bit timer).

CSxxx=b010: Prescaler = 8
WGMxxxx = b0100: Mode = 4 (CTC Mode)
OCR1A = 1000 Prescaler = 8 / Mode 4, CTC mit OCR1A = 1000 @ F_CPU = 8MHz this results in 1ms timer tick IRQ's.

#define TRX_IRQ _BV(INT4)

interrupt mask for GICR

#define TRX_IRQ_INIT ( )

Value:

do{\
                            EICRB  |= (_BV(ISC41)|_BV(ISC40));\
                          } while(0)

configuration of interrupt handling

#define TRX_IRQ_vect INT4_vect

interrupt vector name

#define TRX_TSTAMP_REG TCNT1

timestamp register for RX_START event
