Menu hierarchy with ability to enter floats/ints

Projects General Guidance
1

I've done some searching and most of the posts on how to do a menu with an LCD Keypad shield end up with radio silence. I'm hoping that someone can point me in the right direction.

I have a 16x2 LCD display, that will normally display a value from sensor, like temperature. When a button is pressed, it should take me into the menu system, which consists of this hierarchy and the ability to change the values:

  • Setup

    • Distance

  • Delay (int value in ms)

  • Backlight

    • On

  • Off

I need a way to not only navigate the menus intuitively via the up/down/left/right/select buttons, but also to be able to set the float and int values digit by digit.

Thoughts?

Using the LCD Keypad Shield for simple data entry is relatively easy and I already posted a couple of more or less complex example programs in this forum. Need another one?

But why do you want a hierarchy where there is actually no hierarchy?
And why do you want to use float whre actually only int is needed?

Your configuration is strictly one-dimensional.

Suggested operating modes (you can switch from one to the other by pressing "Select":

  1. Normal display (default)
    2 Set dist / XX.X
  2. Set delay XXX
  3. Set Backlight ON/OFF

In the "Set dist" operating mode you actually would NOT enter a float number but a 3-digit int value in the range 000 to 999 ( just printed with a decimal point in front of the last digit).

Currently I'm in bad health and it's a while ago since I programmed something like that for the LCD Keypad Shield, so I cannot provide you some code in no time.

You don't need word, date or time editing, don't you?

[Edit]: OK. I think the TO is no longer following this thread and so will I.
