Have we talked about this lately?
I know there are pre made dongles out there and I assume there are
published projects that each of us can make. I'd like to know if there
is a COTS solution making anything home made not worth while.
To add a twist to the project - an idea we have been kicking around is a
PIC or Atmel based USB dongle that will serve both as a LIRC receiver
and a display interface.
There are a lot of LCDs and VFDs which are essentially parallel port
devices. A LIRC receiver <=> USB interface based around a processor
could certainly handle an extra parallel port. We (ok, I) envision the
presentation of such a device to be very similar to a once sold Bose
product which controlled a whole stereo system but looked no larger then
an alarm clock.
Let's take this project one step further into reality. Say I, or anyone
for that matter, used one of these batch PCB houses and published the
design. (Well, as in software, beware early adopters.) But think of
it. All you would have to do is buy a PCB from the batch house. If you
find a problem w/the design - fix it. But by all means share what you
find or even submit a newer version of the PCB.
Ok, time for some serious questions:
Say it does make sense to build your own IR-receiver <=> USB dongle.
1) As in all things which claim to be interfaces, what are the two
things we are connecting? Is it clearly a generic remote and LIRC? Or
are there other considerations that most here already take for granted?
(i.e. We here only use JP1 remote controls and only USB dongles that
look like HIDs and ...) Basically, what does the dongle need to do.
2) I know, this is the LIRC forum. But there are so many Linux LCD
efforts this may be the only place to get a (somewhat) unbiased opinion.
What are people using? There's LCD-Linux, LCD4Linux and LCDproc just
to name 3. Perhaps one is more conducive to an LCD (or VFD) hanging off
a USB than the others.
3) Does LIRC have any hooks to "output" IR signals? That is, it
wouldn't take much to put an IR-Blaster on this dongle.
