Многопоточность с использованием Sky mote в Cooja Simulator

Question

Мне нужно создать массив случайных чисел размером 𝑛, чтобы вычислить его сумму элементов и запустить вашу программу на Sky mote в Cooja Simulator. Цель состоит в том, чтобы увидеть, как изменяется температура при увеличении размера массива.

      #include "contiki.h"
#include <stdio.h> 
#include "dev/sht11-sensor.h"

#define MAX_VALUES  4

static process_event_t event_data_ready;

unsigned short d1(float f)
{
    return((unsigned short)f);
}

/* digits after decimal point */
unsigned short d2(float f)
{
    return(1000*(f-d1(f)));
}

PROCESS(temp_process, "Temperature process");
PROCESS(print_process, "Print process");
/* We require the processes to be started automatically */
AUTOSTART_PROCESSES(&temp_process, &print_process);

PROCESS_THREAD(temp_process, ev, data)
{
    static struct etimer timer;
    static int count = 0;
    static float average = 0, valid_measure = 0;

    /* This variable is recomputed at every run, therefore it is not */
    /* necessary to declare them static. */
    float measure;

    PROCESS_BEGIN();

    event_data_ready = process_alloc_event();
    SENSORS_ACTIVATE(sht11_sensor);
    count = 0;
    average = 0;
    valid_measure = 0;
    measure = 0;

    etimer_set(&timer, CLOCK_CONF_SECOND/4);

    while (1)
    {
        /* Wait here for the timer to expire */
        PROCESS_WAIT_EVENT_UNTIL(ev == PROCESS_EVENT_TIMER);
        /* Get temperature measurement and convert it to degrees */
        measure = 0.01 * sht11_sensor.value(SHT11_SENSOR_TEMP) - 39.6;
        /* Sum temperature measurements */
        average += measure;
        /* Count how many temperature measurement we have summed up */
        count++;
        if (count == MAX_VALUES)
        {
            /* Average the sum and store */
            valid_measure = average / MAX_VALUES;
            /* Reset variables */
            average = 0;
            count = 0;

            /* Post an event to the print process */
            /* and pass a pointer to the last measure as data */
            process_post(&print_process, event_data_ready, &valid_measure);
        }

        /* Reset the timer so it will generate another event */
        etimer_reset(&timer);
    }

    PROCESS_END();
}

PROCESS_THREAD(print_process, ev, data)
 
{
    PROCESS_BEGIN();

    while (1)
    {
        /* Wait until we get a data_ready event */
        PROCESS_WAIT_EVENT_UNTIL(ev == event_data_ready);
        
        /* Use 'data' variable to retrieve data and then display it */
        printf("temperature = %u.%u\n", d1(*(float *)data), d2(*(float *)data));
     }
     
    PROCESS_END();
}
