ESP8266 Community Forum

I have a HD44780 I2C Display 16x2.
It works fine on my arduino uno with this lib:
F Malpartida's LCD LIB https://bitbucket.org/fmalpartida/new-l ... /downloads

But it is not possible to compile the sketch on an ESP8266 based hardware. All I get are errors.

I found another lib for ESP8266 -> LiquidCrystal_I2C from drobot.com, but the example sketch does not work for me.
It shows one line full of blocks and one empty line - I can not change this behaviour.

Does anyone out there have the right library for an ESP8266 and this LCD that really works on I2C ?
