I'm well along on an infrared transmitter and receiver, using an AVR '2313 chip. I wonder if there is much interest in this here - perhaps more in the home automation boards. Here's a summary

Receives infrared signals from common TV/audio remotes.
Sends the details of the timing of every bit transmitted to a PC or other device via a serial RS232 connection at 19.2Kbaud.

The PC or other device can send the same information which it received out the serial RS232 to the AVR chip and my program will emit IR of the same timing, to control a device.

Hardware: Olimex (or equivalent) AVR protoboard ($15?). a '2313 or equivalent chip. IR receiver chip ($4), from Radio Shack, Digikey, others. IR diode or emitter from some IR device like an IR blaster.

My AVR code. Visual Basic demo/test program.

I developed this having found no such AVR based thing on the net. There are lots of receivers, but no bi-directional things.

Yes, I'm interested. I already have Olimex boards that support most of the non-mega AVRs including the 2313. I'm not much on Visual Basic though.

I would also like to see the code and schmatic on that project. I could see several uses for that type system.

thanks

Within the next couple of months I was about to start a similar project. I had already ordered the Zilog Z8 Encore development kit for the project. However, this morning I just learned of the AVR controllers (having followed a thread in the newsgroup comp.home.automation) and this is looking a lot better. My needs are a bit more extensive - I need to be able to control 17 remote IR devices. They are zone keypads in a Channel Plus whole-house audio distribution unit. Other than that, it sounds very similar to what you are doing, including learning ability which it looks like you already have. I would be extremely interested in learning more about what you have done.

thanks,
Dave

I am working on a similar project for controlling the speed of ceiling fans. I had done a similar project using ST6210 2 years back. I am interested in knowing what you have done in detail.
Thanks,
Kiran
