Hey guts i wrote i code where i need to save 2 int's in flash when i hit a button with intrerupt but when i disconect my microcontroler variable resets.Help pls.

#include <Wire.h>
#include "LiquidCrystal_I2C.h"

#include "MspFlash.h"
#define flash SEGMENT_D
#define flash1 SEGMENT_C

byte address = 0x27;      // LCD I2C address
int columns = 20;         // number of columns on LCD
int rows = 2;             // number of rows on LCD
LiquidCrystal_I2C lcd(address, columns, rows);

int i1=20;
int *pi1=&i1;
int i2=0;
int *pi2=&i2;

int i11=30;
int *pi11=&i11;
int i22=0;
int *pi22=&i22;

void setup()
{
  Serial.begin(9600);
  pinMode(GREEN_LED, OUTPUT);
  lcd.init();
  pinMode(PUSH2, INPUT_PULLUP);
  attachInterrupt(PUSH2, blink1, FALLING); // Interrupt is fired whenever button is pressed
}
void loop()
{
  i1=i1+1;
  i11=i11+1;
  digitalWrite(GREEN_LED,HIGH);
delay(100);
digitalWrite(GREEN_LED,LOW);
delay(100);
lcd.setCursor(0,0);
lcd.print(i2);
lcd.setCursor(0,1);
lcd.print(i22);
}
void blink1()
{
Flash.erase(flash);
Flash.write(flash,(unsigned char*) pi1,sizeof(int));
Flash.read(flash,(unsigned char*) pi2,sizeof(int));

Flash.erase(flash1);
Flash.write(flash1,(unsigned char*) pi11,sizeof(int));
Flash.read(flash1,(unsigned char*) pi22,sizeof(int));
}

 

Where are your main( ) and attachInterrupt( ) routines?
