Post by thread:[PIC]: IR remote control

part 0 44 bytes his is a multi-part message in MIME format. part 1 372 bytes content-type:text/plain; charset=koi8-r (decoded 7bit) 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...

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 Datech, Sweden Patrick J {Original Message removed}

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.

I'm interested too. Please Cc. Thanks, Cristian At 11/30/2001, you wrote: {Quote hidden}>I made such a project a few years back... been in daily use for years. >Its a 2 channel setup as in 2 doors.

> Why don't you post the link to the list :-) 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. /PJ -- http://www.piclist.com hint: The PICList is archived three different ways.

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 :-) /PJ ----- Original Message ----- From: "Josh Koffman" <.....listsjoshKILLspam@spam@3MTMP.COM> > How did you receive the signal?

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.

I would like a copy for my own use, and if you don't mind, I'd like to put it in my PIC Archive online at http://www.ubasics.com/adam/pic/archive.shtml -Adam Patrick J wrote: {Quote hidden}>I used a special chip to decode the IR signal on another PCB >since I wanted generic building blocks.

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 . {Original Message removed}

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?

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 . {Original Message removed}

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...

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?
