menu navigation

Hope this is in the right format.

I can navigate the menu but seem to be always stuck in case 1: or case 2: I cant seem to change the Rtc parameters as I just get put back into the menu.

From power up the LCD shows Time and Date

Code:

void loop()
{
  if (menuRoot == true)
  {
    lcd.setCursor(4, 0);
    lcd.print(rtc.formatTime());
    lcd.setCursor(3, 1);
    lcd.print(rtc.formatDate());

I then navigate the menus using the encoder

Code:

void readEncoder() //read the encoder and set lastButtonPushed to values used by navigateMenu()
{
  n = digitalRead(encoder0PinA);// n is current state of encoder0PinA pin
  if ((encoder0PinALast == HIGH) && (n == LOW)) // check if encoder0PinA pin has changed state
  {
    if (digitalRead(encoder0PinB) == LOW) 
    {
      lastButtonPushed = 1; //if it has changed and its now low decrement  encoder0Pos;
    } 
    else 
    {
      lastButtonPushed = 2; // if it has changed and its now high, increment encoder0Pos
    }
  } 
  encoder0PinALast = n; // set the variable holding the previous state to the value n read above
}

Then using case 1; or case 2 of the void navigateMenus, I move Left/Right through the menu till I get to for example "Min" from void menuChanged.

Code:

void menuChanged(MenuChangeEvent changed){

  MenuItem newMenuItem=changed.to; //get the destination menu

  lcd.setCursor(0,0); //set the start position for lcd printing to the second row

  if(newMenuItem.getName()==menu.getRoot()){
    lcd.clear();
    menuRoot = true;    
  }
  //MENU SET CLOCK
  else if(newMenuItem.getName()=="menuSetClock"){
    menuRoot = false;
    lcd.clear();
    lcd.print("Set Clock");
  }
  else if(newMenuItem.getName()=="menuItemHr"){
    lcd.clear();
    lcd.setCursor(0,1);
    lcd.print("Hr");
  }
  else if(newMenuItem.getName()=="menuItemMin"){
    lcd.clear();
    lcd.setCursor(0,1);
    lcd.print("Min");
  }
}

Now that I have "Min" displayed on the LCD. I select it by pressing the encoder push button on pin 45.

Code:

void menuUsed(MenuUseEvent used){ //                  **if you have a function call it here**
  if ( used.item == menuItemHr ){
    lcd.clear();//etc.
    lcd.setCursor(0, 0);
    lcd.print(rtc.formatTime());
    changeHour();
  }
  else if ( used.item == menuItemMin ){
    lcd.clear();//etc.
    lcd.setCursor(0, 0);
    lcd.print(rtc.formatTime());
    changeMin();
  }

  if ( used.item == menuExit ){
    menu.toRoot();//etc.
  }
}

This now shows the LCD displaying the clock. because of the function changeMin() called from void menuUsed above

Code:

void changeMin(){

  //min=rtc.getMinute();
  if(digitalRead(encoderPushButton) == HIGH)
  {
    min = ++min % 60; //  this is better than // min += 1;as it rolls overfrom 59 to 00
    //if (incrementMinuteButtonPressDectected) min = ++min % 60 // increment and rollover past 59
    //if (decrementMinuteButtonPressDectected) min = (--min + 60) % 60 // decrement and rollunder past 0 
  }
  rtc.setTime(hour, min,sec);
}

At this point If I use the encoder case 1 or case 2, it does not change the Mins on the clock. It simply navigates the menu left or right.

but if I press the encoder push button, the minutes change
