This is a menu management library created as a front end to set parameters in embedded hardware control applications, leaving the back end under application control. It is suitable for text based displays (eg, LCD modules) with 1 or 2 lines available for display.

Menu managers in embedded systems are generally not the main function of the application software, so this library minimizes the use of RAM and has a small memory footprint overall, leaving more space for what really matters.

The library allows user code to define:

• Static menu definitions to minimized RAM footprint.
• Callbacks for navigation and display control.
• Menu inactivity timeout.
• Auto start on key press, or manual start by user code.
• Input methods are available for
  • Boolean (Y/N) values.
  • Pick List selection.
  • Signed integers.
  • Time values (minutes, hours, days, seconds).
  • Decimal floating point.
  • Engineering units.
