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.

    I am trying to design a system to allow me to control me AV system
    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.

    Hi

    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

    Does anyone know if the stamp is fast enough to create the signals for a
    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,


    Leroy

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

    Sure ... we do that at Parallax all the time. Check the web site for
    documentation and code.

    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.

    Sid, do you have a website or anything where I could check out your design
    some?

    Thanks a lot Bruce, that web page should really help me out, I'm new to
    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.
