Rabbit IRDA Info

Started by pjascol July 12, 2005
Hi

Can anyone point me towards information on the IRDA features of the
rabbit. I have looked at the manuals but cant find much info.
If you search the rabbit web site, it lists the features of the chips
and say that they have IRDA but dont go into any detail

Cheers
Peter


Right. I understand that you will have to create a
protocol stack to make it work.

I am also in the same predicament.

My name is Karthik Krishnamurthy I came across your post regarding IrDA protcol on teh rabbit groups. I was wondering if you were able to create the protcol stack/ drivers. If so, can you point me in the right direction as to how to go about it? Or are you willing to sell the driver you created?

Yes, z-world, while proudly touting the IrDA capability of the rabbit processor neglects to mention that they don't supply an IrDA stack. So you can't communicate with anything high-level like a PDA. I investigated this in some depth about 2 years ago. The cheapest commercial IrDA stack I could find (with source code) was $30,000! I did eventually find a public-domain stack implementation called pico-IrDA, though it only supports the minimal functions - from memory, it was slave mode only, and fixed 9600baud (but check for yourself, I don't remember too clearly). I started porting it to DynamicC, but the project got shelved before I got far. If you can live with max 115200bps, you can buy IrDA chips that handle the whole business - hardware and software - and they only cost a few dollars. Microchip is one manufacturer. But if you need the higher speed IrDA modes - 1 or 4Mbps (which I did), I am not aware of any canned solutions. You'll probably need a book to explain the IrDA protocol, because its pretty complicated. I have "IrDA principles and protocols" by Knutson and Brown. Its adequate - certainly better than reading the IrDA spec - but not brilliantly written. Maybe look for something else on amazon.

A couple of years ago we did a design with IrDA using an RCM3000 and used an IrDA chip from Microchip. It connected up to the serial port of the Rabbit and acted just like a UART. You even set it up just like a UART. It handled all the IrDA protocol, no protocol stack required, and it spit out serial data and took serial data to and from the Rabbit. We used a PDA to communicate with the unit. It was really quite easy. If you can use a UART you can use this IrDA device from Microchip. I believe the part number was MCP2150. ----- Original Message ---- From: Will Keogh To: r...@yahoogroups.com Sent: Wednesday, September 6, 2006 7:57:38 AM Subject: [rabbit-semi] Re: Rabbit IRDA Info Yes, z-world, while proudly touting the IrDA capability of the rabbit processor neglects to mention that they don't supply an IrDA stack.

Hi there I used an MCP 2120 connected to a Toshiba TFDS 4500 IR device. One thing to watch out for, is that there must be a beefy capacitor de-coupling the IR device.

Sounds like a hardware problem ;> ----- Original Message ---- From: Alexis To: r...@yahoogroups.com Sent: Wednesday, September 6, 2006 11:40:28 AM Subject: Re: [rabbit-semi] Re: Rabbit IRDA Info Hi there I used an MCP 2120 connected to a Toshiba TFDS 4500 IR device.
