ARDUINO IDE and LCD 20x4 I2C problem - help please

Hi all,

I have bought this display (http://www.ebay.ca/itm/Blue-Serial-IIC-I2C-TWI-2004-204-20X4-Character-LCD-Display-Module-For-Arduino-/191226723781?) for my Arduino DUE original. I tested the IDE (1.6.7 to 1.8.2) with all library. I tested 2 models LCD 20x4 I2C.

Unfortunately I can't find a way for make this LCD working 'after reading many post on many different websites. I always have compile errors or no errors and LCD blank. (with trying different libraries and sketches). Is there anybody that find a way to program successfully LCD 20x4 I2C and could help me?

The Arduino DUE recognize the LCD at address 0x27.

Please question: does anyone have this combination in working order? If yes, please refer to the IDE version, library and test.ino. Thank you, mpcz, 08.may.2017
