Awesome work man!!!

Wow,, it showed a signal over 100?? I didn't know it could be that high.. This stuff is pretty oddly documented!

Rather undocumented... Not sure what you use, but if it is the WirelessInfo structure defined in Apple80211.h then it is a 16bit integer. I can't find the documentation, but for a 26 step NSLevelIndicator, the code looks (and works) like this:

Code:

    WirelessInfo networkInfo;
    WirelessContextPtr context;
    context = NULL;

    WirelessAttach(&context,0);
    WirelessGetInfo(context, &networkInfo);
    
    [signalGauge setDoubleValue: (networkInfo.signal/2520)];

Not sure any more how I got the 2520 constant, but it works :-)

Hi man! I'll try that out tonight. I've been using the WirelessNetworkInfo.signal number. I didn't know what to do with the large number (like 60,000) I get from useing WirelessInfo.signal. I'll try with that constant you derived.

Thank you

Aychamo, I was browsing for GPS Mac programs when I found this...

"FourCoordinates is a Mac OS X framework written in Objective C for listening to GPS devices connected to Macintosh computers. It takes care of interpreting the output of the GPS device and presents you with a simple class interface for obtaining the current coordinates, and being notified when they change. Its goals are ease of integration, zero user configuration (i.e., autodetection of GPS devices), and support for a broad range of GPS devices. It includes a demo application called WhereAmI, which displays current GPS information."

MacUpdate Page

I dont know if it will help but just in case, I posted it.

sounds like it might help with getting something to work with google earth

**aychamo** · 09-11-2006, 11:49 AM

Well, I did a little investigation with GoogleEarth. It doesn't support the ability to allow external programs to control it's window position. It allows commands to tell it where to go (like I can have AMP zoom in on a lat/lon @ a distance), but I can't change the window size.. I may be able to just have a window stick on top of it at all times, but that would hide the bottom part of GE's window..

Also.. Don't you ahve to have an internet connection for GE to be able to zoom in and get the zoomed in graphics?

Yes unfortunately. People have gotten around it by caching their whole town or trip, but that is a super pain...

**LightningMac** · 09-11-2006, 12:30 PM

I still think it's the best free solution at the moment, I doubt anyone wants to pay over $100 for routebuddy. (in my case $99.50 for the program and $69.50 for a map of North America) I would just cache a long trip in advance or just keep my local area cached, not that big a deal for what it does and the fact that it's FREE...

Does GE support like if you have a GPS unit, updating real time where you are?

**LightningMac** · 09-11-2006, 02:23 PM

I think it does, as long as you have someway of sending it a live signal from your GPS unit.

on a seperate note, this looks interesting:

iGuidance Plugin almost ready, need everyones input
