IR Remote Control
hi guillermo masco,
The stamp is to slow to do anything worthwhile with IR remote
control signals unless a IRDa uart or somthing like is used I am
currently working on a remote control project that uses IR remote
signals i have spent about six months researching IR Remote
control stuff if you need any help please don't hesitate to ask.

via my laptop. I have already tried and succeeded in reading SONY
remote control signals howver my TV and VCR are Sharp and DVD player
is JVC. Neither of those remotes I can read.
I read online about 3 different styles of IR communication, varying
different parts of the signal.
I was wondering if anyone had any information on reading the signals
from Sharp/JVC remotes or just sending those signals to their
respective appliances.
Thank you for any assitance.

One of the best things you can do is use a Scope, by using one of the IR
receivers from Radio Shack (metal can one) all you need is 5vdc you can look
at the different ways they use there pulses, some have a start bit of given
length some change the first part for device i.e.. TV, VCR and DVD. using a
scope is a must for seeing timing differences. I have done Three remotes
that I had on hand only one was Sony ( the easiest ) and I did nothing with
the VCR outputs other than look at them with a scope. Look through the
archives I posted the code I had sometime this year, last few months I
think, they were for a pic f84 written in PBP so a faster stamp may be able
to handle this, good luck. If you cannot find the postings let me know I
will look them up.

I wouldn't bother. Pick up a cheap universal remote. Open this remote
and solder directly to the keyboard matrix contacts. Remove the
rubber buttons, you will see where to make the connections.
From there you can have your PC tell your stamp to operate the
remote.
Good Luck

Stereo or TV remote control? I know the carrier is at about 40 KHZ but
is the stamp fast enough to supply the modulation?
Thanks,

Kinda ... If you use FREQOUT enough harmonics are generated to modulate an IR
LED. We use this for IR object detection on our robots.

Jon, I've read the IR Remote Control documentation, but it deals with IR
LEDs. Do you have anything on using a TV Remote Control ? I've written a
program to read and decode a Sony Remote but am looking for ways to improve
it.

Jeremy, I have written a program for the BS2 that reads and decodes a Sony
Remote. Press a button on the Sony, press Enter and the Stamp closes a relay
on one of two relay boards. Press another button and Enter and it closes a
relay on a second relay board. Still in development but the program is
working pretty good. Stamp drives a 595 shift register which drives a UL2003
array. The 2003 actually controls the relays.

this newsgroup but this is so helpful. I think I'd been searching for an
article like that for a while.

You're welcome. It's an excellent article for the Stamp & infrared. If you're
just
getting started, I highly recommend poking around the Parallax site and taking
advantage of the application notes.
Here's a link with all kinds of interesting projects for the Stamp:
http://www.parallaxinc.com/html_files/downloads/downloads_appkits.htm
We also have a Stamp section online: http://www.rentron.com/BasicStamp.htm
If you're interested in sending serial data via infrared, we have a new widget
that
works great with the Stamp here: http://www.rentron.com/remote_control/TX-IR.htm
It can be used for:
Direct RS-232 PC serial port infrared send & receive interface
Buffered RS-232 send & receive interface with the max233
Infrared communications with microcontroller interface
Push-button remote control transmitter & receiver w/relay
Object detection w/relay control
And Al Williams has a load of intersting Stamp projects too at:

Sorry, Jeremy. Don't have a website. Programming for this project has been
quite difficult - code has about 5000 words and I haven't really finished
yet. And then I have to get it from the 877 in FlashLab into a16F876 in a
circuit.

Sid,
Would you be willing to share your preliminary code
& schematics? I'd be interested in seeing your
approach to this.
