> What size LCD should we use
What sort of prices/size are they?
Something that fitted into a UK double is probably too small so I suppose
we're pretty free to use whatever shape/size seems best.
> Should the LCD be text or graphics
I would say graphics. This possibly makes things more complicated though?
Text might be faster/cheaper to develop.
> Should the LCD be backlit
Deffinately.
> Do we need a light sensor to determin if the backlight is on
No. If it's mains powered there's no reason not tho have the backlight
come
on every time it's used.
> How many keys do we want
Are there are similar designs we can look at? Things like Next, Previous,
Enter, Cancel spring to mind.
> How do want the keys positioned, under lcd for menu operation ?
?
> Do we want a IR receiver in the unit
Would be nice but may complicate things.
> Do we want a local temperature sensor.
As above.
> What sort of conversations do we want it to have with other devices
Hmmmmm...
:-)
