Apple IR Controller?

Has anyone ever gotten the Apple IR controller that comes with an iMac to work using the IR code for the propeller?

I've tried all the examples that I can find and 7 different IR units and cant get any to work..

k.

    Could you please be a bit more descriptive ?.

    Do you mean the remote controller ?. Which IR receiver are you using ?. Have you had a look at the pulse train that comes from your IR receiver ?. If you do not have an oscilloscope, you can get the propeller to act as a logic analyzer. I think cluso or heater have developed some hardware/soft combination for that.

    Ale's right ... give us more info!

    Do you want to read the IR sent by the IR controller with a propeller or do you want the propeller to generate the same IR code? What's your setup? Do you have a IR diode for input or do you have a IR receiver which already removes the carrier signal?

    I am using the prop and a standard 38k Ir receiver ( PNA4602M ) and what I am trying to do is use the IR remote ( any IR remote at the present ) as a keyboard substitute to move/hi-light and select items in a list of items. That's why I chose the Apple remote .. nice and simple, and the fact I had it sitting around..

    When I get a chance I'm going to wire up another test unit using my proto board so I can have serial out to debug using the code in OBEX from JonnyMac..

    Sony IR remotes are simple to decode, easy to come by, and there's a load of good code for them -- including the program I PM'd you last night. It's very likely that the protocol used by the Apple remote is proprietary, and not worth trying to figure out. RC-5 is another easy protocol (from Philips) that many of us have written code for.

    It looks like I'm going to have to find another remote ( any suggestions ) ..

    Basically I have tried every remote in my house to get any type of info out of into my prop .. My Apple one, 4 different universals, and even my controller from sony for my Trinitron TV ( plus any others I found.. ) .. and I get nothing.. So I am going to pick up a usb to serial programmer for my prop so I have the serial terminal to debug with and start there..

    I gotta dig out the manual for my universal controller and config it for sony as well and maybe that will work..

    Thanks for the code help Jonny..

    Okay, quick google search. Someone says apple uses the NEC protocall:

    http://wiki.altium.com/display/ADOH/NEC+Infrared+Transmission+Protocol

    So you would have to get the correct IR reciever to decode the button presses

    Never mind, its just the protocall you need. NEC is 38 kHz too

    Have you tried the IRKit from the Obex?
    I've used that a bunch of times to figure out remotes and it's got some great discussion of IR in the code and directions.

    Thanks for the tip CannibalRobotics ... I got IR readings.. using the M5 settings.. now to figure out what the output means... but at least we're in the right direction...

    I read somewhere that the Apple remote uses a diff. freq. I think I read it in a forum all about carputers. If I recall correctly, much faster. That may be your
    problem.

    Do a google to prove me wrong smile.gif

    Of coarse I ran the ir_view code and played and found out all of the codes, which matched up with the info I found on a linux site, but now for the life of me I can't get the specific nec reader code to work.. it has configuration settings not in the documentation..

    So I trudge on.. I may just rewrite the ir_view code to suite my purpose.. I need more time..
