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.
- Decimal floating point.
- Engineering units.
