Detailed Description

This board is describes the Sensor Terminal Board from Dresden Electronic. It is a carrier board for the RCB family.

The Sensor Terminal Board is a carrier board 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
     PD6  <--  CLKM
     PD4  <--  IRQ (ICP1)
     PB5  -->  RSTN
     PB0  -->  SS
     PB2  -->  MOSI
     PB3  <--  MISO
     PB1  -->  SCK
    The STBxxx has memory mapped LEDS and Keys.
    KEY: PE5
    LEDS

  • 2 x memory mapped at 0x4000 (Option 1)
  • 3 x IO mapped at PE2:PE4 (Option 2)
    You can select between using the LEDs on the RCB or on the STB.
    In order to use the RCB LEDS, you have to define the macro USE_RCB_LEDS.
    The LEDs on STB have a write-only memory interface, so we can't read back the LED status.
    So we need to have a shadow register, which stores the current LED state.
    Since the board interface consists only of a header file, we use register
    GPIO2 on ATmega1281 for shadowing, because it would be hard to ensure the
    single instantiation of a global variable from a header file, which is used
    in many module files.
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
Original Settings w/ rdk231
     LF: 0x61
     HF: 0x91
     EF: 0xfe
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.
