The best solution that I have seen to this is to use an I2C - 8 bit
I/O converter from Phillips (PCF 8574 Remote 8 bit I/O expander for
I2C bus: see http://www.semiconductors.philips.com/ps/gif/3042.gif)

This can then be used to connect to any normal LCD with a 7 bit
interface.

By the way, does anyone know a good US source for the PCF8574??

Thanks,  Mike

I just looked it up 10 seconds before I read my mail. Marshall has 6471
PCF8574PN in stock at $3.03. Don't know if that's good or bad.

Whoa!

Some time ago I mention the existence of these beasts. I have received
plenty of mail requesting more info.

I just have to find it first, then I'll post it on the list.

Are there any I2C LCDs available?
Alternatively, i spose the code would be easy to write for an F84 or summit.

Philips have some I2C graphic LCD controllers
