Found a new way to handle the HID USB using API

[Weather Display]

I found some sample code that uses the built in API routines for handling HID USB (e.g WMR100/200, Irox stations)
so I just now need to make some calls to those routines...
the routines get around the problem had previously where the Mac would take over control of the HID device (thinking it was a mouse or keyboard)
so if I get this to work, will not need to rely on weathersnoop to supply a data feed

Hi Windy

I'm really looking forward to this new improvement...

I would like to return to the Mac version, but not before it's rock stable, and without weathersnoop.

Cheers

reports are that the latests .zip updates are stable (unless you use FTP/real time ftp and you have an unstable internet or a ftp server that is slow or non responsive at times etc...the solution there would be to instead use scripts to ftp the needed files)

In case you're interested, here's working driver for Mac OS X HID manager. This particular implementation is for WMR100 or compatible devices.

Hi
looks good
does it do the initialisation OK?
(i.e in testing of the one I found I still had to initialise on windows first)
Are you also good at windows HID API  calls?

Hi, sorry for long delay, I forgot to switch on the Mail notifications...

Yes the code initializes the Oregon Stations properly (I have WMR100 and WMRS200) and is very stable. It also should work as a basic driver with any HID-based USB station, just enter the proper vendor/device ID and replace the function that assembles the readings from the station.

Is the code you had available somewhere? I could take a look and see why it fails initializing. Shouldn't be too hard.

Unfortunately I'm completely newbie when it concerns Windows USB stuff so I can't help you with that. But I do know that there's a HID manager for C# that's supposedly rather easy to implement stuff with.

Hi
just getting around to looking at this
https://github.com/ejeklint/Cloudya/blob/master/daemon/WMR100NDeviceController.m
do you have this compiled and working in xcode?
if so, could you send me that xcode project
or better yet are you able to compile it as a c++ shared library file?

I tried compiling, but its missing WMR100NDeviceController.h

thanks!

[Weather Display]

I have found were you had made a xcode project available
http://lists.apple.com/archives/usb/2009/Aug/msg00029.html

looks like it requires OS 10.6
which I do not have

Yes it compiles fine in Xcode, and the .h file is on Github too: https://github.com/ejeklint/Cloudya/tree/master/daemon

As for Mac OS version, I believe that the new HID manager was introduced in 10.5 so it really should work for 10.5 too. I'm not sure if I can set up a 10.5 compatible Xcode project since I'm on latest version myself, but I'll give it a go tomorrow. Otherwise a simple makefile should do the trick.

Hi
I have tried compiling in xcode by get lots of errors
in NSobjCRuntime.h
I might be missing some development libraries

it would be really good if you could compile a .dylib where I can call that with some functon calls
e.g to open/close the USB port
and to get the raw data packets passed through

I cleaned out the Objective-c stuff from the file and supply a simple Makefile to build a dylib. Note that while it compiles fine for me, I haven't actually tested it after the cleanup and I've only built it on Lion since that's what I have. But I hope it helps as an example.

[Weather Display]

Hi
thanks very much, I was able to compile it OK (using make)
so now I will try callling the functions and see what happens

[Weather Display]

Hi
before trying to call the .dylib, as a test,
I tried creating a xcode program using your code
and compiled in C as a command line ultility (tool)
but I get all these errors

any ideas?

[ejeklint]

Looks like link errors to me. You must add the libraries IOKit.framework and CoreFoundation.framework to your Xcode project.

that worked, thanks
now I need to add some code to open and then get the data....
