Just a suggestion concerning the internal structure of such an adapter:
If you look at Documentation/i2c/smbus-protocol it seems to be better to
implement it only using the SMBus subset of the I2C protocol, if at all

Seems good, the address would be an integer between 0-127 for the standard
7-Bit I2C-addresses? The 10-Bit addresses are included in the I2C standard but
the kernel support is only experimental since no known I2C devic

Do you know how to talk to the i2c via user-space?(Something like libusb or
tty system). Then a non-w1 approach would be easy. There is an example
implementation for the DS2482 in the kernel; module, and the communication
structure is an easy match for OWFS.

I will definately build a board based on the DS2482-800 chip and will test
owfs improvements, too.
Hi,
I'm hoping to have a circuit, and PCB design done over the weekend.
Still waiting on the arrival of a sample chip from Maxim, once I've got
the designs finalised I'll make them available for comment.

Agreed, I just copy-pasted from your post.

Just to avoid confusion
The I2C part is DS2482-x00
x = 1 for 1 port
x = 8 for 8 port

Paul,
This is great
Hello,
first of all I apologize for breaking the thread but I just subscribed because
of the recent discussion about kernel w1 adapter support.
As I understand you were looking for beta testers and their specific setup
(thread started by Stuart Poulton on Feb 27, 2006).
We are planning to attach
Paul,
This is great news.
I've got samples on the way from maxim of the 2804-x00's so hopefully
will have a prototype interface available for testing soon.
Cheers

After extensive discussions with Evgeniy Polyakov, it looks like OWFS will be
able to use the linux kernel 1-wire drivers as a possible 1-wire adapter

OWFS natively.
