Hello,

Is there a way to use serLCD.h instead of the library you had implemented ? I'm using that library to communicate with a 1 wire serial LCD which are not supported yet by the LCD Libraries included.

Thank you

neu-rah commented 9 years ago 
Can you post a link to the library and
  lcd model?

  thanks

Hello,

Here the display I'm using : https://www.sparkfun.com/products/9395 The library to drive it : https://github.com/nemith/serLCD which is an update of the library you can find on Arduino.cc playground website : http://playground.arduino.cc/Code/SerLCD I had a look on your files, and all the LCD lib seems working with SDA/SCL or in parallel mode - but maybe I'm wrong.

Thanks

    Looking at the library it looks ok.

  the display menu driver is similar to:
  https://github.com/neu-rah/ArduinoMenu/blob/master/menuLCD.h

  duplicate it and just use the menu lcd driver virtual functions
  (write,clear,setCursor) to call the apropriate LCD functions on
  your driver

  please, let me know about it

Hello,

After several tried it seems that everything works fine now, thanks you for your help. I have a question, on a 20x4 LCD, I limited the menu to 2 lines with the command

menuLCD lcd(lcd1,20,2); // Let only 2 lines available for the menu

Is there a way to place the menu on line 2 and 3 instead of 0 and 1 ? Also, is it possible to get a kind of menu index to know where I am. For example, am I inside the main menu or inside a SubMenu, and which one?

Thanks in advance

Hi, I'm glad its working

No problem, If you fill like sharing it just fork the project and
then do a pull-request with your changes.

I have a question, on a 20x4 LCD, I
    limited the menu to 2 lines with the command
    menuLCD lcd(lcd1,20,2); // Let only 2 lines available for the
    menu
    Is there a way to place the menu on line 2 and 3 instead of 0
    and 1 ?

Positioning the menu

class menu:public menuNode lets you position the menu by changing
members ox,oy

example:
MENU(mainMenu,"Main menu",
    /*OP("LED On",ledOn),
    OP("LED Off",ledOff),*/
    OP("Disabled option",none),
    SUBMENU(onoff_tog),
    FIELD(param,"Name","%",0,100,10,1)
  );

just call 
mainMenu.oy=2

before using the menu (possibly arduino setup function)

Also, is it possible to get a kind of
    menu index to know where I am. For example, am I inside the main
    menu or inside a SubMenu, and which one?

Yes

the menu device object has a menu* to the last drawn
menu
your driver derives from this class (menuOut) defined in menu.h

them pointed object (menu) has int sel member that
is the select menu option
menuPrint menu_out(Serial);//describe output device
  menu_out.drawn //<-- the active menu
  menu_out.drawn->sel // <-- selected line

I've not tested this code samples but let me know if there is some
problem

Thanks for using the software, hope it can be as helpful as it was
for me

Hello,

Thanks a lot for all the tips and informations. Unfortunately, neither the position and index information is working.

Here the menu setup, MENU(m_Main,"Main menu", OP("Test 0", nothing), OP("Test 1", nothing), OP("Test 2", nothing) );

//describing a menu output, alternatives so far are Serial or LiquidCrystal LCD menuLCD lcd(lcd1,20,2); // Let only 2 lines available for the menu

menuPrint m_output(Serial);//describe output device

Here my code for the setup (only the part) void setup() { Serial.begin(9600); Serial.println("menu system test");

quadEncoder.begin();
// Switch on the backlight and set display
pinMode ( BACKLIGHT_PIN, OUTPUT );
digitalWrite ( BACKLIGHT_PIN, HIGH ); // 70
lcd1.begin(20,4);             // initialize the lcd
lcd1.clear();
lcd1.home();                   // go home
lcd1.print("Menu test");

pinMode(encBtn, INPUT);
digitalWrite(encBtn,1);

pinMode(LEDPIN,OUTPUT);

m_Main.oy=2; // set the position on LCD on line 2 instead of 0
// m_Main.setPosition(0,2); // I also tried this method without any success on positioning

}

And the code for the loop, for debug

void loop() { // testing the menu system m_Main.poll(lcd,quadEncoder_button);

m_output.drawn; //<-- the active menu
Serial.println("-> Active menu : ");
m_output.drawn->sel; // <-- selected line
Serial.println("-> Selected line : ");
delay(300);

}

I had a look inside menu.h, but I don't have strong c++ skills, so the tips you gave me should work, but... I saw a public method in class::menu called setPosition, but it did not work too. Any idea of what I did wrong ?

As I'm continuing to test and try this nice menu class, I would like to know if there is a possibility to hide the menu (can be done by lcd.clear();), and show it up by moving encoder or press en encBtn ? I know that lcd.clear(); only erase the screen, but all the interruptions behind are still running.

Thanks a lot !

Hello,

After few trials and trying to understand your code I notice that effectively m_output.drawn->sel works perfectly. I just didn't find the way to know that I'm on top of the menu tree, so at this time I test canExit property which is not the best way, but it works.

Did you see my question about the possibility to show and hide the menu ? Is there an another way to do than clear/redraw ?

Thanks a lot for your help.

neu-rah commented 9 years ago

class menuNode (base of menu) has a static member menuNode pointing to the current menu. therefor

menuNode::activeMenu;// is the current menu
menuNode::activeMenu->sel;// is the index of selected option (hilited)

and I've just added functions redraw and focus

neu-rah commented 9 years ago

would you be kind enought to share the one-wire lcd driver? if so just fork and pull with driver

christophepersoz commented 9 years ago

I finally use the LCD library extended by Bill Perry that can be found there : https://github.com/Xerxes3rd/LiquidCrystal. It's a smart library because a lot of driver chipset are available.

Add the following lines for the includes on I2C :

`#include

include //LCD driver for IIC by Bill Perry (https://github.com/Xerxes3rd/LiquidCrystal)`

and then,

LiquidCrystal_IIC _Display(0x3f, IIC_PCF8574, 2,1,0,4,5,6,7,3,POSITIVE); // Define 20x4 LCD Display on I2C bus at address 0x3F / 63

There is a smart private method inside this library that can help you to locate the address of your LCD device on I2C bus. In my case the manufacturer mentioned the wrong address on the documentation.

After that, I just use the common declaration

//describe output device menuLCD _menuLCD(_Display,20,4);
