Since posting my OneWireViewer App+Source for Mac OS X last August, I still see fairly regular downloads of it in my stats. I also still see lots of hits from google searches for “1-wire” and “mac osx”. I thought I’d let any interested parties know that we are gearing up to release our 1-Wire Public Domain Kit (C code) very soon (likely this month). I put in some effort for this release to create a specific Serial (DS9097U) and USB (DS2490/DS9490) build for Mac OS X. The release will include full source and a build file, as well as pre-built Universal Binaries of all of the example apps. Those without much programming knowledge looking to integrate 1-Wire into bigger systems should appreciate that.
Learning how to build the Universal Binaries was a bit of a chore, but once you get the hang of it it’s fairly simple. The biggest complication was building a Universal Binary for libUSB and since I wanted my libUSB-dependent app to be Universal, I had to jump through hoops to get it to work. I was able to get 0.1.12 to build an Intel library just fine on my Intel Mac (though <= 0.1.11 didn’t work for me, so mind your sources). I couldn’t get it to build the Universal binary due to it’s use of ‘ar’ and ‘ranlib’ (which, according to this tech note from Apple does bad things to Universals). I’m not a configure or makefile whiz and I got a little stumped on the parts of the makefile where gcc was being used to generate new makefiles dynamically (wasn’t aware of this feature before). Apparently when using -MT (to generate new makefile rules) you can’t pass multiple architectures along with your compile command (i.e. “-arch i386 -arch ppc”). I ended up doing things the hard way and just compiling the PPC binary on a PPC mac, and then merging the two with lipo (i.e. “lipo -create -output uni.lib ppc.lib intel.lib”). After all that, I discovered a nice pkg installer for a Universal libUSB that someone else was nice enough to pre-build and distribute for us. I recommend this installer for the easiest path to a Universal binary of libUSB.
My next task is to recompile my Java-to-libUSB-to-1-Wire solution (for OneWireViewer and the rest of the examples in the 1-Wire API for Java) as a Universal Binary. I also need to put a little effort into making it work with libUSB on Linux, so I can update the “live” WebStart version of OneWireViewer with virtually out-of-the-box support for every platofrm. The 1-Wire API for Java was scheduled for release this quarter (ending in 2 weeks), so I hope to have all this done in time to ship out the door with the release.

I’ve finally gotten around to creating a source tarball for the work I did to get the Public Domain Kit support files for libUSB running under the 1-Wire API for Java. 80% of the work here was figuring out what to do, so you’ll find there isn’t a lot of code to glue them together. It would be pretty easy, for example, to swap out the PDK files for libUSB with the DS1410E link-level files for Linux. Then you could have parallel port support using the 1-Wire API for Java under Linux as well as the USB port.
The Makefile is geared towards Mac OSX. Everything else, including the C source in the ‘native’ folder, is platform independent and should compile everywhere libUSB does. Using Sun’s reference on how to build JNI libraries for the various platforms, you should be able to modify the Makefile to support your platform. If you have any suggestions for improving the build process, especially if you can help make it a cross-platform Makefile, then please let me know.

I had a few people post in the comments about getting a copy of the OneWireViewer update I did… A few email me privately. I’ve been emailing it out to people as it’s requested, but now that I have a good web hosting service, I may as well put it out on the intarweb proper-like.
For now, this is a binary-only distribution. I want to do some more testing with it and make a similar binary distribution for Linux before I make this official. Once I’m convinced that it’s as robust as the PC solution, we’ll move it over to the official Dallas Semiconductor ftp site. Although most of the source is available online (1-Wire API for Java and 1-Wire Public Domain Kit on maxim-ic.com, libusb on libusb.sourceforget.net, rxtx on rxtx.org), some of the glue I used to make this work isn’t. I’ll try to make that available soon to people who want to dig around in that part of it.
Don’t blame me if this application sets your pretty Macintosh computer on fire.

If you have any success with this at all, please leave a comment and let me know.

Take a look at this screen capture to see how I spent my 4th of July vacation weekend.
I ended up taking the libusb build of the 1-Wire Public Domain Kit and creating a JNI-wrapper around it. Now I’ve got a nice USB Adapter driver for the Java API (and hence for OneWireViewer). I’m going to look into modifying the WebStart download so that it will deliver the new USB adapter and the binary (JNI) portion of it. Possibly, I can sneak the libusb drivers along with that as well, without causing too much confusion. Maybe make 2 builds, one that includes libusb for people who aren’t cmd-line savvy enough to build their own and one that doesn’t.
The good news is that this should work on Linux, Mac OSX, and Windows. Windows users will have to install a .inf file first, but it will be a single-click application for Linux and Mac.
Update (7/10/2005): I used JarBundler to create a nice .App bundle of this for Mac OS X users. It’s pretty nice to have a installable .App of OneWireViewer that supports both the USB Adapter (DS9490) and the Serial Adapter (DS9097U) on Mac OS X. Unfortunately, I don’t have a good place to host it.. I’m not sure in it’s current form if it’s suitable for an official release to go up on the dalsemi ftp servers. So, if you’d like to try it, just leave a comment and include your email address (not in the comment, but in the regular email address field, where I will be able to see it but noone else will) and I can email you a copy of the app. It’s 2.3mb compressed.
