Ibutton to ASYNC serial

Can you use one of the serial iButton adapters??

If not, maybe it'd be easier to do the 1-wire interface "by hand" than to find a chip to connect to your system's serial port? Just a thought.

You can read an iButton with a standard UART - see the Dallas App Note.

I guess I should be more clear.

My embedded system needs a way to read some calibration variables.

I would like to use the DS1992 and I have an async port available.

So, pc based solutions are out of the question.

I guess I know what I'll be doing this long weekend.

Thanks

DS2480B is the current solution for this from Maxim. They'll send you couple of samples just for asking.

I guess you should. See below.

Why? For what? This is completely meaningless lacking context.

In general on usenet you should realize that readers may very well not have convenient access to previous articles in a thread. That means that your reply articles should include adequate context, so that they stand by themselves. Google is NOT usenet, it is only a very poor interface to the real usenet system. To include proper context when using google, see my sig. below. Please be sure to read the referenced URLs.

Looks interesting. I'll take a closer look.

Thanks

I didn't suggest a pc based solution. Your embedded system has a uart so you can read the one-wire device with it. If you say pc based because the app note is pc based, think outside of the box (pc) - it works for an embedded system just as well. I've seen it implemented on both platforms.
