Dear all,
I´m working around a Display Menu for my needs and i´m not the best code writer. After Googling and trying a lot of examples i could find and build something that i can use for the start.
The idea is that i can change the value of 2 counters and 2 timers over the sreen with buttons.
How the code is right now it´s possible to change the values individuality. + or - 1000 cycles and + or - 1000 millisec.
unsigned long parameters[numOfScreens] = {1000};
But what i would like to have would be a individual value changing for the 2 counter and that i could choose over a option being 10, 100, 1000 or 10000 steps increasing or decreasing the counters. I have tried already to make it work but i´m reaching my coding limits. I would be thankful for some help. Of couse if there is a better way than the one that i´m going now with my code, i would be also thankful for some suggestions.
Follows down the code that i have until now
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
//Input & Button Logic
const int numOfInputs = 3;
const int inputPins[numOfInputs] = {6,7,8};
int inputState[numOfInputs];
int lastInputState[numOfInputs] = {LOW,LOW,LOW};
bool inputFlags[numOfInputs] = {LOW,LOW,LOW};
long lastDebounceTime[numOfInputs] = {0,0,0};
long debounceDelay = 5;

int currentScreen = 0;
String screens[numOfScreens][2] = { {"Counter1", "Cycles"}, {"Counter2", "Cycles"}, {"Timer1","MiliSec."}, {"Timer2","MiliSec."}};
unsigned long parameters[numOfScreens] = {500};

lcd.setCursor(5,1);

}
if ((millis() - lastDebounceTime[i]) > debounceDelay) {
if (reading != inputState[i]) {
inputState[i] = reading;

inputFlags[i] = HIGH;

}
lastInputState[i] = reading;
}
}

}
}
}

}
The code how it´s right now works fine
