Hi,
I want a rockbox-capable, video capable, small, 60gig+ player. It seems
the iPod video is perfect, except for one thing, it doesnt have a LCD
remote (which is the killer feature of my H140).
Looking at
http://www.rockbox.org/twiki/bin/view/Main/IriverHardwareComponents#Remote_Control
and
http://ipodlinux.org/Dock_Connector
it seems that the iPod doesnt have any digital IO lines on its dock
connector, but does have a serial interface.
I was thinking we could have a PIC chip connected to power and serial on
the iPod, with a simple program to drive the LCD remote. I imagine it
would accept a serial input from the iPod and bit-bang the data into the
LCD remote, and monitor the buttons for presses and return them to the
iPod via serial.
Of course, it would require software support on the iPod, but now we
have a (almost working) Rockbox port, that should be simple.
The main problem I see is that this would not be 'mainstream' so I would
be left porting my changes to each new release of Rockbox. And getting a
connector to mate with the odd iRiver remote.
Of course, the Rockbox project could 'adopt' a LCD remote of some kind
Any comments? anyone know of a LCD remote that already works via serial
only? (how do the Sony minidisc ones work?) ideally one that is still in
production.

On sony minidiscs the buttons use a resistor network with different
values for each button. The ones with a display use serial comms for
this part of it AFAIK. It's a while since I had one though.
