Your display of two rows of blocks is an indication that the LCD is not properly initialized. You do not have the correct permissions to perform this operation.

Let me know what you need and I will post. But I am able to adjust the contrast and tried already all “positions”: I read of some Problems if the contrast isn’t adjusted properly. Forums Posts Latest Posts.

There are also no bridges between pins: Added new getAddress method. I traced the problem and it turns out the ‘busy signal’ never goes low after initialization, which I could only think it means the initialization isn’t complete.
