LCD display + tijd en temp weergave

[Fourstar Profiel Privébericht]

Wie kan mij helpen : heb nog niet voldoende kennis maar wel interrese

link naar lcd :http://www.bitsandparts.eu/LCD_Display_HD44780_-_20x4_zwart_op_geel-groen_(Displays_and_EL_wire)-p100070.html

samen met een : http://www.bitsandparts.eu/I2C_interfac ... nd_EL_wire)-p100062.html

en een DS3231 voor tijd en temp.
alles werkt in de ser. monitor zoals het hoort maar krijg het niet te zien op het display 2004A 20x4

wanneer ik een andere code oplaad vb:" hello world " of iets dergelijks geen probleem alles ok.

kan code niet opladen is een .ino code
wel doorsturen via mail indien gewenst.
of is er een andere weg ?

Niet ulpoaden maar wel gewoon hier zetten. Je laatste sketch van de internationale site:

cpp code

/*-----( Import needed libraries )-----*/
#include <Wire.h>  // Comes with Arduino IDE
// Get the LCD I2C Library here: 
// https://bitbucket.org/fmalpartida/new-l ... /downloads
// Move any other LCD libraries to another folder or delete them
// See Library "Docs" folder for possible commands etc.
#include <LiquidCrystal_I2C.h>

/*-----( Declare Constants )-----*/
/*-----( Declare objects )-----*/
// set the LCD address to 0x3F for a 20 chars 4 line display
// Set the pins on the I2C chip used for LCD connections:
//                    addr, en,rw,rs,d4,d5,d6,d7,bl,blpol
LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);  // Set the LCD I2C address
