Hello PICers!
I have universal IR remote control and i would like to make receiver
with PIC for it.
Output must be with relay - i will control contactors for opening
garage.
Code which i will transmit isn't matter - it would be nice if I can
program it in source code of PIC
Any suggestions, schematics, sources are welcomed...
THANKS!

I made such a project a few years back... been in daily use for years.
Its a 2 channel setup as in 2 doors. I'll check if the files are easily
accessable if so then i can send you :
-Working asm source
-OrCad schematics, possibly as pdf
-OrCAD pcb layout

I'll mail you the whole shebang offliist :-)

Best regards

Hi Patrick,

How did you receive the signal? Did you use the capture/compare module,
a TMR, or just polling? I'd really like to see your code if possible.

Thanks,

Josh

Sorry cant post a link to my archived files on tape ;-)

hehe, this seems to be a very popular subjet !
My mailbox was full today w reqs for it :-)
I am mailing the design to the ones asking asap.

I used a special chip to decode the IR signal on another PCB
since I wanted generic building blocks. Like add an IR reciver is
just a matter of connecting the IR-recive pcb to the main pcb.
So the PIC is used to handle the system logic but has almost
nothing to do with the actual IR decoding.

I've used the IR decoder pcd in several projects ever since.
Its loaded with switches so I can change its recive mode by
flipping switches back and forth fast and easy.

If your looking for RECS80/RC5 IR direct decode asm this isnt
for you I think. If you on the other hand is looking for a simple
way to get IR in your design this is a nice little project :-)

You're right, it may not be what I need. Still, now I'm interested to
see what it is :) Please send it to me if you get the chance.

'[PIC]: IR remote control'

Hi all
I designed a satellite dish positioner 4 yrs ago , using pic16c84 and
opto-isolator , i made the infra red link utilizing the  satellite's ir
reciever chip ( which is quite cheap ) and some software to decode the
buttons . i will post it on the list when i get home , 2 - 3 weeks time . it
uses only one pin of the pic which makes it great if u want to interface a
keypad to your project and u r pushed for pins .
the circuit worked beautifully and i managed to convert my cheap receiver
into a full positioner version which was over double the price at the time .
and i still use it today with my digital sat receiver .

That sounds great Mahmood, I'm looking forward to it. Just out of
curiousity, how did you handle the incoming signal? Did you just poll,
or use the CCP or TMR modules?

Thanks,

Josh

Sorry Josh i can't remember how i did it exactly coz it was long time ago ,
but what i remember is that i measured the signal of the remote control on
the receiver end by using a digital storage scope , i figured out the format
of the signal and i compared over 10 types of sat remotes , the code was
quite intresting and i will post it also with the other stuff when i dig
through my old archive . I'm planning of rewritting the whole project with
hi-tech c , i did it in mplab asm at the time , no changes will be made to
the hardware coz i had no problems with it so far .
I think i may have used RB0 int for counting the dish position pulse from
the sensor (16 bit counter) and used RB4 pin change interrupt for measuring
the IR pulse widths to decode the key , i used TMR0 to measure the width of
the IR pulses of course and u have to give it a margin of error . I tested
it intensively and got the right key pressed every single time .

It looks like the major obstacle to overcome is the SAA3049 decoder chip.
Then there might be a problem with the acquiring the encoder as well...

Now searching alternatives...

Hi,

Check this URL:

http://www.geocities.com/SiliconValley/Sector/3863/uir/index.html

It contains some (almost) universal receiver code and you can add the other
parts.

Best regards
Les

I need this stuff:
When i send for eg. code 1 then to start first relay to opent gate
when i send code 2 to close gate - two codes, tow separate outs
That's it...
I just do not have time wo playe with in in ASM
I have remote control with PCA84C122
Thanks!

Actually, I looked at that page a few days ago. It contains just the hex
file...I can't seem to find actual asm code. Did I just miss it?
