free software 1-wire (DS18x20) library (AVR, ARM)?

	BTW, is there any good 1-wire "master" interface library (as
	used, e. g., to communicate with the DS18B20 temperature
	sensors), which happens to be free software?

	I'm aware of the Peter Dannegger & Martin Thomas work [1], yet
	neither in the code nor on the Web page can I find any
	permission whatsoever to reuse the code (or even to run it!)

	I've also seen a number of such libraries for the Arduino
	platform (including [2, 3]), which happen to rely on C++ and the
	usual set of libraries, thus making me think that they may
	end up being a bit too heavyweight to use "in production."

	TIA.

You are idiot.
It takes about 15 minutes to DIY.

There is clearly something wrong with someone who feels the need to 
demean others for the slightest infraction of their "rules".

Will you get a life and stop being such a rude, condescending toad?  You 
actually have something to contribute, but you pollute the very waters 
of these groups with your raw lack of respect for others.

Yes, you always cease to amaze me.  You should hang out with the s.e.d 
crowd.  I think you would fit right in.  But then again, you don't seem 
the type to stand up for yourself.  In s.e.d you would probably be eaten 
alive.

I'm glad Vlad responded.  That reminded me to respond to the OP...

There are any number of 1-wire libraries around.  Just do a little 
searching and I'm sure you will find one.  It is not really a 15 minute 
exercise but it is not so difficult to write one.  The specs are not 
totally clear on how to implement in software.  At one time they just 
plain didn't give the full range of timing info needed to properly spec 
the interface, but I think that has been fully rectified by now.  You 
just need to set a small set of timing values to control the reading and 
writing of the bus.  The other part is enumeration of the devices out 
there.  Again, you need to read the protocol and make sure you 
understand how it works.  All this will help even if you are just using 
someone else's library.

Rickman,

Have you already built your long promised WWWB clock?
No ?
Is it to tough for you, lamer?
Go and do it, pathetic windbag.

Yes, you are perfect for s.e.d.

If you use the CodevisionAVR compiler, you get a 1-wire library .
You pay for the compiler, but you get quite a lot of library code for
free.

Hi Ivan,

I tracked down Peter Dannegger on avrfreaks and he said "All my code on the forum can be used for free."

Martin Thomas was happy for his modifications to be used under a BSD licence.

So it should be possible to get permission to use the code if you need it.

Regards,
Alex
