TinyOS如何与TelosB硬件通信？

Question

关于TelosB的整个系统是如何工作的，我有一个非常基本的问题。我已经看过了数据手册和TelosB是如何操作的。

现在我需要通过TelosB节点发送一些特定的数据。我看到了TinyOS的数据包格式。并定义了有效载荷。

  typedef nx_struct packet {
      nx_uint16_t id; /* Mote id of sending mote. */
      nx_uint16_t count; } packet_t;

在无线电计数leds代码中，我更改了几个小东西

    #include "Timer.h"
    #include "RadioCountToLeds.h"



     module RadioCountToLedsC @safe() {
       uses {
       interface Leds;
      interface Boot;
       interface Receive;
        interface AMSend;
          interface Timer<TMilli> as MilliTimer;
         interface SplitControl as AMControl;
        interface Packet;
      }
        }
           implementation {

       message_t packet;

       bool locked;
     uint16_t counter = 0;

   event void Boot.booted() {
      call AMControl.start();
     }

      event void AMControl.startDone(error_t err) {
   if (err == SUCCESS) {
     call MilliTimer.startPeriodic(250);
     }
    else {
      call AMControl.start();
      }
     }

     event void AMControl.stopDone(error_t err) {
      // do nothing
      }

   event void MilliTimer.fired() {
      counter++;
     dbg("RadioCountToLedsC", "RadioCountToLedsC: timer fired, counter is 
        %hu.\n", counter);
       if (locked) {
        return;
        }
         else {
          radio_count_msg_t* rcm = (radio_count_msg_t*)call 
  Packet.getPayload(&packet, sizeof(radio_count_msg_t));
  if (rcm == NULL) {
return;
  }

  rcm->counter = 11110000;
  if (call AMSend.send(AM_BROADCAST_ADDR, &packet, sizeof(radio_count_msg_t)) == SUCCESS) {
dbg("RadioCountToLedsC", "RadioCountToLedsC: packet sent.\n", counter); 
locked = TRUE;
  }
}

}

计数器是我想要传输的数据。是11110000。当此TinyOS代码在Telosb微尘中运行时，如何解释11110000？我需要非常具体地说明哪些数据将进入telosb或OQPSK的DAC。

我想详细了解数据是如何读取和解释的。
