Return to Question

i am from Argentina.

Iam making a kind of proyect for my car, and one of the many functions i am thinking, is to check how many times the arudino has been powered up.

I was thinking a simple counter and save it to the eeprom (using the SETUP VOID).

I was able to save the value, and read it, but i cannot add +1 to that value stored in the eeprom.

#include <EEPROM.h>

char buffer[15]; // Largo de la variable, cantidad de caractares
int cant;

void setup()
{
   Serial.begin(9600);
   Serial.println("Write to EEPROM: ");
   EEPROM.put(0, "12345678901234");

   Serial.print("Read from EEPROM1: ");
   Serial.println(EEPROM.get(0, buffer));

   Serial.print("Read from EEPROM2: ");
   Serial.println(buffer);

   Serial.print("Read from EEPROM3: ");
   cant=(EEPROM.get(0, buffer));
   Serial.println(cant);
   
}

void loop()
{

}

And i am getting as output:

Write to EEPROM: 
Read from EEPROM1: 12345678901234
Read from EEPROM2: 12345678901234
Read from EEPROM3: 370

The variable CANT is showing a diferent value.

I am making a kind of project for my car, and one of the many functions I am planning, is to check how many times the Arudino has been powered up.

I was thinking of a simple counter and save it to the EEPROM (within setup()).

I was able to save the value, and read it, but I cannot add +1 to that value stored in the EEPROM.

#include <EEPROM.h>

char buffer[15]; // length of the variable, character count
int cant;

void setup()
{
   Serial.begin(9600);
   Serial.println("Write to EEPROM: ");
   EEPROM.put(0, "12345678901234");

   Serial.print("Read from EEPROM1: ");
   Serial.println(EEPROM.get(0, buffer));

   Serial.print("Read from EEPROM2: ");
   Serial.println(buffer);

   Serial.print("Read from EEPROM3: ");
   cant=(EEPROM.get(0, buffer));
   Serial.println(cant);
}

void loop()
{
}

And I am getting as output:

Write to EEPROM: 
Read from EEPROM1: 12345678901234
Read from EEPROM2: 12345678901234
Read from EEPROM3: 370

The variable cant is showing a different value.
