1-wire devices

Posts: 46,084
Is there any practical way to use a Stamp (Javelin in my case) to
access a 1-wire device? So far, what I've read indicates that i need
special chip, such as the DS2480B, which Parallax does not sell.
Parallx, how abou putting one of these chips onto a carrier board?
Pretty please?

and look for BL233 ic.
Here is the datasheet
http://www.i2cchip.com/bl233_a.pdf
This is a 18 pin dip package and thus easy to
handle also on breadboard.

usability on a breadboard, but for the fact that I don't have to use a
straight-pin to solder it!
Any idea where it can be purchased, and for how much? Any idea
when/if it will no longer be "Preliminary"? That document is a tad
difficult to read!

Scroll down to Host Adapter Products
There you find the bare IC's.
They are sold per 10 ($39.50 per 10) which you can order online.
Also check out Bus Connectors and Cables
in case you need their special connectors.

Have you actually used the BL233 with a Stamp? If so, I'd like to see
some code and schematics. I have ordered some, along with the special
crystals, etc.

I did order and received 10 BL233's about two months ago, together with the
USB/RS232 adapter.
I haven't found the time yet to play around with them., also because I do
not use 1-wire devices.
I ordered the USB/RS232 because it can be connected directly to the second
comport on the
javelin demo board. If I find the time I want to check its I2C speed. The
javelin can send
at 57600 baud, which is about 6 times the software I2C speed (someone once
reported
the software I2C speed to be approx. 10kbit/s). The reason I was interested
was because of
my compactflash interface that interfaced via I2C (a poor 6.5 seconds per
sector, but it does work).
Now I have ordered some new boards and do the interface with an SX28 @ 20MHz
so I
won't need the BL233 for my CF. I reserve them for 1-wire devices for
future use.
If it does what is stated in the manual it should be a great companion for
the javelin for 1-wire,
and for the BS2 and BS2SX for both 1-wire and I2C.
