Hi all,
I'd love to use my BeagleBoard as an entertainment device using the
Griffing Technology Powermate as the main input interface (I love
those big aluminum knobs) and a small LCD as visual feedback.
I'm aware of such a thing with the PSP LCDs using the raw LCD
interface on rev C2, but I'd like to ask you what do you think about
something easier and straigh forward like a small OLED LCD I2C driven
by the expansion port.
Since I want to do something rather simpler than soldering small
pitched connectors (even if it would be way cooler, but I don't have
here what it needs to accomplish that), I'd like to know if you're
aware of any good and easy to find small lcd (also a serial one or
something coming from used cellphone).
It would be perfect with a backlight to be quite visible, but at this
very moment I'm just curious to find a starting point solution.
Thanks for any kind of suggestion, it will be very much appreciated.
Kind regards,
Daniel

You could try this but you would still need a level shifter circuit:

This is I2C based. I don't think there are kernel drivers yet but you should
be able to add one based on the same code. For what you want to you, you
might be able to cobble together all the control you need from userland, thus
avoiding the kernel driver entirely.
If you don't need graphics (or can use character graphics), there are tons of
alpha numeric LCDs that can be interfaced with trivial glue logic. A lot of
those use a similar command set and depending on your choice of glue logic,
you can complete avoid anything finer pitched then 0.1" - just use TO-92
cased transistors for logic level shifting.
Or you can get my prebuilt 480x272 LCD interface (see my website, it is
available, send me a PM; the merchant listing stuff is hitting some snags.)
