Hello,
I would like to have your help, I used your library to create my menu, I use an arduino mega 2560, a LiquidCrystal screen 20 * 4 I2C and a rotary encoder on pins 2,3 and 4, when I compile and transfer the program to my card nothing is displayed.
My screen works very well because I have already tested, I did not change anything in the program generated by the GUI. I put the right I2C address and the right pins in parameters.
Can you please help me !
