[iw2fvo]

Steve,
Thanks.
I have no more pins available on the pic and I have this LCD on my hands.
Anyway, what LCD ( 20x4) with serial interface could you suggest to me ? I could try to get one.
Regards,

The good news is that it can be done here is some code.

If you need more help just ask,

[EarlyBird2]

Does this code work?

If it does we can use it as a starting point and adapt it for your use.

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

Let me know when you have a replacement. I am confident that we can get this to work between us. You do the testing and I will help with the programing.

I would do it all but I do not have the hardware anymore as I went over to touch screen PLCs. I am more interested in touch screen GLCD solutions based on a PIC (Amicus18 for example) which I need the hardware for.
