Hello, I have the following problem.
I can not run an I2C LCD through an arduino duo, which gives me the following error. I'm glad if you help me.
WARNING: library LiquidCrystal_I2C claims to run on (avr) architecture(s) and may be incompatible with your current board which runs on (sam) architecture(s).
Sketch uses 25252 bytes (4%) of program storage space. Maximum is 524288 bytes.

I guess you included an LCD Library for an AVR ?
Examples of LCD via I2C over a DUE:
I have the same warning using LiquidCrystal_I2C on Due, but the display is working anyway. FYI I use 5V supply for display and level converter for I2C.
Ciao, Ale.
