Discussion Groups | Rabbit-Semi | Re: Rabbit IRDA Info
This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.

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.

Re: Re: Rabbit IRDA Info - Steve Trigero - Sep 6 12:40:43 2006
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.

Re: Re: Rabbit IRDA Info - Alexis - Sep 6 16:35:27 2006
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.
