MENWIZ: yet another character lcd menu wizard library

Using Arduino Displays
65

You have the same LCD I tested. So it must work :slight_smile:

Brute force approach
Here attached you can find the libraries directory I'm using under Arduino-1.0 IDE.
Delete MENWIZ directories everywhere. Backup your current libraries directory. Delete it. Drag and drop libraries directory from the attached zip file.

Test it with the following code

//MENWIZ ESAMPLE
#include <Wire.h>
//INSERT ALL THE FOLLOWING 4 INCLUDES AFTER INCLUDING WIRE LIB 
#include <LCD.h>
#include <LiquidCrystal_I2C.h>
#include <buttons.h>
#include <MENWIZ.h>

// DEFINE ARDUINO PINS FOR THE NAVIGATION BUTTONS
#define UP_BOTTON_PIN       9
#define DOWN_BOTTON_PIN     10
#define LEFT_BOTTON_PIN     7 
#define RIGHT_BOTTON_PIN    8
#define CONFIRM_BOTTON_PIN  12
#define ESCAPE_BOTTON_PIN   11

//Create global object menu and lcd
menwiz menu;
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Addr, En, Rw, Rs, d4, d5, d6, d7, backlighpin, polarity

//instantiate global variables to bind to menu
int tp=0;
int  gp=26;
boolean wr=0;

void setup(){
  _menu *r,*s1,*s2;
  _var *v; 
  int  mem;

  Serial.begin(19200);  
  
  // have a look on memory before menu creation
  Serial.println(sizeof(menwiz));
  mem=menu.freeRam();
  
  // inizialize the menu object (20 colums x 4 rows)
  menu.begin(&lcd,20,4);

  //create the menu tree
  r=menu.addMenu(MW_ROOT,NULL,"MAIN MENU");           //create a root menu at first (required)
    s1=menu.addMenu(MW_SUBMENU,r,"MEASURE SUBMENU");  //add a submenu node to the root menu
      s2=menu.addMenu(MW_VAR,s1,"Choose T scale");    //add a terminal node in the menu tree (that is "variable"); 
          s2->addVar(MW_LIST,&tp);                    //create the terminal node variable of type OPTION LIST and bind it to the app variable "tp"
          menu.getErrorMessage(true);
          s2->addItem(MW_LIST,"C°");             //add an option to the OPTION LIST
          s2->addItem(MW_LIST,"F°");           //add an other option to the OPTION LIST
          s2->addItem(MW_LIST,"Raw data");     //add the third and last option to the OPTION LIST
      s2=menu.addMenu(MW_VAR,s1,"Set T1 trigger");
          s2->addVar(MW_AUTO_INT,&gp,10,100,2);
      s2=menu.addMenu(MW_VAR,s1,"Enable heater");
          s2->addVar(MW_BOOLEAN,&wr);

  //(optional) create a splash screen with some usefull infos 
  //the character # marks end of line (WARNING: this could be changed in the next releases)
  //(tip): use preallocated internal menu.sbuf buffer to save memory space!
  sprintf(menu.sbuf,"MENWIZ TEST V %s\n.Free mem. :%d\n.Used mem  :%d\n.Lap secs  :%d",menu.getVer(),menu.freeRam(),mem-menu.freeRam(),5);
  menu.addSplash((char *) menu.sbuf, 5000);
 
  //declare navigation buttons (required)
  // equivalent shorter call: menu.navButtons(9,10,7,8,11,12);
  menu.navButtons(UP_BOTTON_PIN,DOWN_BOTTON_PIN,LEFT_BOTTON_PIN,RIGHT_BOTTON_PIN,ESCAPE_BOTTON_PIN,CONFIRM_BOTTON_PIN);

  //create a user define screen callback to activate after 7 secs since last button push 
  menu.addUsrScreen(msc,7000);
  }

void loop(){
  // NAVIGATION & DRAWING MANAGEMENT
  menu.draw(); 
  //PUT APPLICATION CODE HERE
  }

// user defined default screen
void msc(){
  sprintf(menu.sbuf,"User screen\nUptime (s): %ld\nFree mem  : %d\n\n",millis()/1000,(int)menu.freeRam());
  menu.drawUsrScreen(menu.sbuf);
  }

Let me know
