I no longer have Eagle installed, but I believe this is the file you requested. Let me know if it gives you problems and I'll figure it out.

That was exactly the file needed. Looks like you did some revisions some time after the actual release of the design.

I have a code base, that in combination with a 24F16KA101, would allow for both the North American code database, and the European code database to co-exist, and the method to run them, would also make use of the second button. The way it would work, is that one region would be the default one to run, when just the reset button is pressed, and running the other, is a matter of holding the stop button, while pushing reset, then releasing the stop button. (Pushing the stop button a second time, stops the sequence playback as usual.)

Hi, first of all, thank you for sharing your design!!
I was wondering if the code could be ported to another PIC more "affordable". I mean another pic not as new as this one that could be burned with a standard programmer..

Thanks!!

i have a working code for the pic18f2550 or similar that works with the internal oscillator and can send both the european and american code.
Contact me if you want it.

Thank you very very much! :)
I'll try to get my hands on 18F2553 and test it.

Cheers!

I've tried to compile this code for 18F2555 and compiling went ok, I burned the HEX file and when I watch IC LEDS (with my phone camera) they flash very briefly and It takes about 1:45 sec to loop trough all the codes.
However when I try to turn of any TV...nothing happens :\
Can anyone please help me on what I'm doing wrong here? :\

If you are in the usa you have to use this:

I'm from Europe.
Do you have any other idea why it isn't working for me?
It takes about 1 minute and 45 seconds to loop trough all of the codes (EU), and LEDs flash very briefly, I guess that's ok?
I tried it on 10-20 TV and none of them turned off :\

Are you using a correct wavelenght ir led?
Where do you connect it?

I was able to get my hands on LTE-5208 IR LEDs, in datasheet it says that wavelength is 940nm and forward voltage of 1.2V.

I connected 4 of these with 100ohm resistor to base of NPN transistor on port RC0 (PIN11 of PIC18F2550)

Here is my schematic http://imgur.com/pwRxPWN

You have to collect the ir led on the RC2 pin 13 of the pic.
The RC0 is the userled and it is a non infrared led that blinks when the PIC sends a code.

Darn, how didn't I notice that :S I feel so stupid about it now.
I will re-wire the PCB and let you know if it works :)
