Thanks Steve for the kind assistance,
I can not test the code soon : the day before yesterday my display went off. I ordered another one and will be here in two weeks tiime.
Anyway : the dispaly is exactly the same of the one shown in the images attached to the link you have sent to me.
I really think that a smart code to control the i2c LCD will be appreciate by a lot of people that use PBP.
Thanks a lot for helping.
Regards,
Ambrogio
