Hi Guys,
This is a little off the wall, but I am designing an interface unit
for controlling power usage in homes and the built in LCD screen can
only be utilized to display a finite amount of information and I
desire a way to interface the unit to a larger screen in some
applications. The obvious thing would be to make the application web
based and the user can utilize a PC to communicate with the
controller, etc. But in cases where a computer is not available or
is considered too complex for non-techies, I am wondering if there is
a clever way to display information on the home owner's TV screen to
achieve a larger format display. What jumped to mind were things FM
audio transmitters that are used for iPods to shuttle audio to a
standard FM radio. Very cheap and they work well. The idea is to do
something like that, but for video and use the TV tuner as a display
for the user interface. The information would only need to be basic
textual information, not full motion video.
Can anyone think of any neat, practical ways of getting basic textual
user interface information from an electronic control unit to a TV
screen? Wirelessly would be nice, but I suppose it would have to be
done like the early home computers (Commodore, etc) where a TV
modulator was wired into the RF input of the TV.
Thanks!
Paul
If you're in Europe then your TV will have a SCART connector and you
can feed it an RGB signal. The STV5730 is a handy chip for this.
