After scouring the interwebz and this forum and finding no real solution, I'm am building a library of VIs to interface with a 1-Wire network. I have several of the pieces built and tested to the point where I can search a network and retrieve the serial number (ROM code) for all devices attached. Before I go much further, I would like to get some comments, advice, hints, and general feedback about the VIs as they are and how to move forward with this project. Is there still any interest in this?
This code is for a (likely) one time project and may never be used again. However, if it can be done correctly and may be of use to anyone else in the future, I would prefer to put in the effort rather than just hack something together.
One of my primary concerns regarding the code, besides general architecture, is the handling of errors and some situations which are not actually errors. This has always been a thorn in my side when building programs in LabVIEW.
This project is targeted for use with the DS9490 USB adapter and is written in LabVIEW 8.0. If anyone has any interest, I'd be glad to here from you.

We are runing LV2015/Win 7 Pro 64 but would like to try your VI Lib.
It looks like what we need.
Not sure what the setup is and what dependances are to get in running.

That would be very nice.
Thanks...

Here are the VIs as used in my last project. I really don't have time to document this mess but, if you want to use it, feel free.

Thanks I will look at them.

Hi all,
There is a Tools Network solution in widespread use here:
https://www.interfaceinnovations.org/onewireproducts.html
I would suggest downloading the packages from the site, as they are more frequently updated than the Tools Network.
It's quite easy to use with many examples, and supports many devices. If you value your time, it will easily be worth it for you. Give it a trial and see if you agree.
Kind regards,
Colin

Hi,
I are very interested in this VI library. But I have a problem for communicating with 1-wire adapter DS9490R。The NI Max can't find the device. So would you please tell me how to configer the PC so that I can control this USB adapter. Thanks very much in advance.

Hi.
You do not find it in NI Max. You install the 1Wire Drivers from Dallas/Maxim and use them to locate your device and set it to default. You can then test it using the Java app that comes with the package.

Hi Colin,
Thanks for your reply. I know the method you said and It is ok in my PC. But now I use labview to control this adapter so I need Max to find it.
