MENWIZ: YET ANOTHER CHARACTER LCD MENU GENERATOR LIBRARY


DESCRIPTION
- (near) asynchronous: the library does not take mu control while working; 
  this is usefull if your sketch need to work while you are using menus
- simple to use (compact and simple code, ortogonal interface)
- user defined splash screen (optional): if you need to show something at
  startup; time elapsed is user defined.
- user defined callback screen (optional) activated after a user defined 
  elapsed time since last button push. The menu gently leave the screen to
  the user sketch code, untill any button is pushed.  
- user-defined actions (callbacks) from inside the menu
- user defined variables binding: associate (bind) a sketch variable to any 
  menu object, whenever a value is changed inside the menus, the program 
  has direct access to that value via its own (binded) variable  
- built in 6-buttons and 4-buttons modes; the user can overload the  built-in
  mode, implementing its own navigation callback (e.g. analog buttons, 
  rotary encoders etc) 
- EEPROM support to save and load variables to/from EEPROM non volatile mamory; 
  it is possible to disable EEPROM support to spare some memory
- use of F() operator to store menu strings in progmem to save the heap 
  (starting from V 1.0).
- menu objects behaviours
- create users and assign grants to visualize menu branches
- Quick tour user manual 

WHAT IS NEW IN THE LATEST VERSION
Latest version: V 1.3.2 (April 29 2014):

- Fixed the option MW_MENU_INDEX bug.
- It is now possible to set up to 3 users and to set access grant to submenus for each one of   them with the following methods:
  menwiz::setCurrentUser(int);
  _menu:: setBehaviour(MW_GRANT_USERx, Boolean);
- New data type added: the long awaited editable text MW_EDIT_TEXT. It works for now *only*   in “6 buttons mode”. The variable is not buffered, that is any change will take immediate   effect: when you leave the variable editing with exit button, the changes will affect the   original char variable.
- The method getLastbutton of the class menwiz let available the last pushed button code

KNOWN LIMITATIONS AND BUGS

BACKWARD COMPATIBILITY

Please read the manual (chhaper "MENWIZ changes history")
 
Warnings:

- MENWIZ requires New LiquidCrystal (*) and Buttons libraries, enclosed with
  the package. The New LiquidCrystal allows to use 4 wires, 8 wires, I2C, 
  serial and other LCDs. The use of New LiquidCrystal is beyond this 
  introduction
- the examples are done for 20x4 I2C LCD. other interfaces and screen dimensions
  can be used accordingly with New LiquidCrystal interface (changing 
  mode/interface does not affect library code, but only sketch code) 
- starting from 0.6.0 version, due to the EEPROM support, the sketch must
  include the file EEPROM.h (until you disable the EEPROM support)

The MENWIZ library is avalable at:
https://github.com/brunialti/MENWIZ
You can download all the stuff as ZIP file.
Due to github policy it is not avalilable anymore the /downloads directory

VERSION NUMBER CONVENTION

<version>.<subversion>.<build>
  <version>: 0=not officially released
             (check the latest available sources, the lib could work  not properly
  <subversion>: new functions, modified function interfaces
  <build>: bug fixing, minor internal changes


The TEST_LIB zip file contains all the library *required* to use MENWIZ lib.

(*) New LiquidCrystal is a replacement of the standard LiquidCrystal and 
    LiquidCrystal_I2C libraries. it is more efficient and very well supported
    The nice thing about the "New LiquidCrystal" library, is that it already 
    supports a wide range of LCD controllers:
    - I2C base on the PCF8574 or compatible
    - 4bit and 8bit parallel
    - ShiftRegister: 3wire, 2wire, 1wire (beta)
