I don't continued with this, but I'm planning to do it when I can. I has no problem on sharing my code.

Ok, this is the image of the display, I will try to make a little protocol analyzer and I will tell you

I do have the phone, then I can monitor the communication. I am suposing it is i2c, then the first thing I need to know is what is the address. With this, I supose I can use try-and-error to figure out the communication.

This is the display:

Then... will try to make a little protocol analyzer. One question: Is there any way to use the wire library to monitor the i2c bus? Something like promiscuous mode or something? or I will need to write a little program for this?

By the way... ┬┐How do I upload an image to the forum?

I'm trying to get working an i2c lcd display borrowed from a wireless phone. The problem is that I has not any technical info about it. The only thing I know is the pins for vss, vdd, sda and scl.

Is there any way to scan the i2c bus in order to figure out what addresses must be used?

Or... is there any way to create a small analyzer? I can connect the display to the phone and connect some pins of arduino. Is there any way to analyze the info using the wire library or I must create a custom program for this?

It would be great if the software on the ATmega8u2 had various usb "personalities" included, selectable by software on the 328.

You could send some special string to 328 to swithch it from usb-serial mode to usb-keyboard mode or usb-joystick mode.

Then, there will be no need to upload new software to the 8u2.

When power off it could return to the default usb-serial mode.
