Hola!!
Estoy utilizando un programa que duerme y despierta a Digimesh. Le he puesto un contador llamado "contador" 
pero se reinicia cada vez que se duerme el Digimesh... alguien me podría echar una mano??
Gracias!!!
#include <avr/sleep.h>
int sensor1 = 1;
int sensor3 = 3;
int val1 = 1;
int val3 = 3;
int wakePin = 2; // pin used for waking up
int sleepStatus = 0; // variable to store a request for sleep
int count = 0; // counter
int led = 13;
int contador=0;
void wakeUpNow() // here the interrupt is handled after wakeup
{
}
void setup()
{
pinMode(wakePin, INPUT);
pinMode(led, OUTPUT);
Serial.begin(19200);
/* Now is time to enable a interrupt. In the function call
- attachInterrupt(A, B, C)
- A can be either 0 or 1 for interrupts on pin 2 or 3.
- B Name of a function you want to execute while in interrupt A.
- C Trigger mode of the interrupt pin. can be:
- LOW a low level trigger
- CHANGE a change in level trigger
- RISING a rising edge of a level trigger
- FALLING a falling edge of a level trigger
- In all but the IDLE sleep modes only LOW can be used.
*/
attachInterrupt(0, wakeUpNow, LOW); // use interrupt 0 (pin 2) and run function
// wakeUpNow when pin 2 gets LOW
}
void sleepNow() // here we put the arduino to sleep
{
/* Now is the time to set the sleep mode. In the Atmega8 datasheet
- http://www.atmel.com/dyn/resources/prod_documents/doc2486.pdf on page 35
- there is a list of sleep modes which explains which clocks and
- wake up sources are available in which sleep modus.
- In the avr/sleep.h file, the call names of these sleep modus are to be found:
- The 5 different modes are:
- SLEEP_MODE_IDLE -the least power savings
- SLEEP_MODE_ADC
- SLEEP_MODE_PWR_SAVE
- SLEEP_MODE_STANDBY
- SLEEP_MODE_PWR_DOWN -the most power savings
- For now, we want as much power savings as possible, so we
- choose the according
- sleep modus: SLEEP_MODE_PWR_DOWN
*/
set_sleep_mode(SLEEP_MODE_PWR_DOWN); // sleep mode is set here
sleep_enable(); // enables the sleep bit in the mcucr register
// so sleep is possible. just a safety pin
/* Now is time to enable a interrupt. we do it here so an
- accidentally pushed interrupt button doesn't interrupt
- our running program. if you want to be able to run
- interrupt code besides the sleep function, place it in
- setup() for example.
- In the function call attachInterrupt(A, B, C)
- A can be either 0 or 1 for interrupts on pin 2 or 3.
- B Name of a function you want to execute at interrupt for A.
- C Trigger mode of the interrupt pin. can be:
- LOW a low level triggers
- CHANGE a change in level triggers
- RISING a rising edge of a level triggers
- FALLING a falling edge of a level triggers
- In all but the IDLE sleep modes only LOW can be used.
