Hi Pascal,
Thanks for this awful chip - i just ordered a free (thanks again) demo
board ...
What are your plans for availability - lets say if i want to use this
device for a commercial application - are the chips still available in,
lets say, 10 years ?!?!
thanks a lot,
marcus.
Hi Rob,
If you plan to use OUT pin for pwm, a *pullup against +5v* is recommended.
Other pwm don't need external pull up/down.
You may connect directly the FET gate to the header, tinyboard already have
a 470 ohms resistor between OUT pin and header.
For an inductive load, it is recommended to
Hi marcus,
Availlability: I really don't have a cristal globe to tell the future, even
less over 10 years...
But if for any reason I would stop this activity, I will pass the relay to
someone else, or even open source the project...
My short planning is to propose alternate board based on the

I'm a newcomer to 1-wire and was a bit disappointed to see the DS2423

I am writing a 1 wire slave library for the AVR series of
microcontrollers.
That should allow you to do all the stuff you want.
Hooking into OWFS might be a little tricky if everyone implements
their own functionality though.
If a standard set of functionalities can be agreed on, (counter,

potentiometer device for light/ballast dimming) that is obsolete without

I have a few thoughts on this.
First, I would love to see a model for DAC as well as PWM for output. A
simple two double byte model with a 16 bit set for signed output and 16
bits for log gain. Clearly there is nothing that you are going to hook
to a 1-wire bus that is capable of this kind of
We've intermittently worked on this. I have one student who has made
the beginnings of PIC code for OW slave interface, although has
implemented very few of the commands so far.
I also have some C code intended for compiling for the Atmel to
implement the timings and raw read/write for slave

Time for open-source PIC/AVR-based implementations! :)

I'm certainly interested.
Is this the right place to do it?
If felt appropriate, I can set up separate sourceforge project for it.

Off topic:
I have also considered making a complete clone of the DS2490 (usb to 1
wire master) on an AVR chip. $30 is too much for a USB - 1wire adapter!
An ATTiny chip should be able to handle it no problem
Would this be interesting?

Anyone have other suggestions for functionality?
Integrator, DAC, bidirectional counter ('quadrature').

I for one will buy a premade unit even if I could make it myself if it

It's fine to stay on this list. The discussion is welcome, in fact.
That's great news - many thanks!
There's definitely a place for a generic protocol for a device that
tells the master the capabilities of each of it's I/O

I also have some C code intended for compiling for the Atmel to
implement the timings and raw read/write for slave devices on the OW
bus. This hasn't been tested at all yet.
Sounds like i'm a bit farther along then
In any case, I may be able to get someone on this over the summer.

Well, i view DAC as primarily a hardware interface to either PWM or PIO
features. The chips themselves (at least AVR) do not directly support DAC, but
you can either do PWM with a Resitor+capacitor smoother, or a R2R
