Hi,
Below is my menu system and I want to store the configurable variable in eeprom.
Any idea or suggestions is welcome.
#include <LiquidCrystal_I2C.h> //addr, en,rw,rs,d4,d5,d6,d7,bl,blpol
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
int Temperature Hot = 0
int Temperature Cold= 0
int Tank Hight = 0;
int Tank Deviation = 0;
int Delay Off Time = 0
int Delay On Time = 0
int Oil Lever HH = 0
int Oil Level LL = 0
int Phone Number = +0000000
int Run Times = 0
//Input & Button Logic
const int numOfInputs = 4;
const int inputPins[numOfInputs] = {8,9,10,11};
int inputState[numOfInputs];
int lastInputState[numOfInputs] = {LOW,LOW,LOW,LOW};
bool inputFlags[numOfInputs] = {LOW,LOW,LOW,LOW};
long lastDebounceTime[numOfInputs] = {0,0,0,0};
long debounceDelay = 5;
//LCD Menu Logic
const int numOfScreens = 10;
int currentScreen = 0;
String screens[numOfScreens][2] = {{"Temperature Hot"," degC"}, {"Temperature Cold", " degC"},
{"Tank Hight"," CM"},{"Tank Deviation"," CM"}, {"Delay Off Time", " Sec"}, {"Oil Lever HH"," %"},
{"Oil Level LL"," %"},{"Phone Number","XXX"}, {"Delay On Time", " Sec"}, {"Run Times","Sec"}};
int parameters[numOfScreens];
void setup() {
for(int i = 0; i < numOfInputs; i++) {
pinMode(inputPins[i], INPUT_PULLUP);
digitalWrite(inputPins[i], HIGH); // pull-up 20k
}
//Serial.begin(9600);
lcd.begin(16, 2);
}
void loop() {
setInputFlags();
resolveInputFlags();
}
void setInputFlags() {
for(int i = 0; i < numOfInputs; i++) {
int reading = digitalRead(inputPins[i]);
if (reading != lastInputState[i]) {
lastDebounceTime[i] = millis();
}
if ((millis() - lastDebounceTime[i]) > debounceDelay) {

}
}

}else{

}
}else if(input == 2) {

}else if(input == 3) {

}
}
void parameterChange(int key) {
if(key == 0) {
parameters[currentScreen]++;
}else if(key == 1) {

}
}
void printScreen() {
lcd.clear();
lcd.print(screens[currentScreen][0]);
lcd.setCursor(0,1);
lcd.print(parameters[currentScreen]);
lcd.print(" ");
lcd.print(screens[currentScreen][1]);
