    I was thinking the same thing as @GREGL
    I'm using the following to initialize my LCD:

    LiquidCrystal_I2C lcd(0x27,20,4);
    lcd.init();

    Don't think I'm using the same Lib either.

      I was just poking around on codebender and found the lib..but none of the examples use all these params.

      IIRC ,I use a different lib...as my i2c lcd controllers are pretty old..byvac from memory.

        Found the new liquidcrystal library while searching my display Funduino/1602.

        The parameters are:

        addr, en,rw,rs,d4,d5,d6,d7,bl,blpol
        

        https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads

        Example:

          Tried the lib out in my setup and it seems to be working just fine so I think I will use that one to so that I can be on the same page as @hek

              These OLED displays seem pretty cool also if the quality is ok and the library doesn't eat up too much space:

              A lot more information being displayed in a much smaller package. Price is similar to the 16x2 LCD and they run on 3.3-5V apparently. Available as I2C also.

                  I have a couple of these (I2C) and they are great.
                  I have tried to use them together with a temp sensor but I failed doing so.
                  I was able to compile and upload the sketch but due to a lack of patience I did not investigate why it failed.
                  My gut feeling is that the problem was the use of too many string values...

                    I have a couple of these OLED displays on order, will see if I can get them working with the sensors.

                      Put together a new example inspired by @gregl for the RTC module.
                      Also added a display to show date, time and temperature.

                      Hi

                      Can you modify code for adding temp sensor to GW.
                      And may be display day of week.
                      Thank you.
