[ANNOUNCE] (QT) E.F.F. Empty Frequencies Finder app!
 

Hey guys, i finally release my QT Empty Frequencies Finder (E.F.F.)!.This app is not just a gui for the E.F.F shell script, is a complete new app (i have been working on it for at least two months), the only common thing is the way of tuning the reciever. I tested the app many, many, many times and works fine (at least on my N900). I would be glad if someone can create a better icon image to put than mine :).

INFO:
E.F.F. (Empty Frequencies Finder) is a utility that lets you choose a range (only 87.5 FM - 108.0 FM) to scan from, for empty/unused frequencies, using the reciever of N900 and headphones as its antenna. For example you can use this utility to find empty frequencies, so you can easily transmit from your N900 to your radio. If you are not satisfied with the emptiness of the frequency scanning results you can select between modes, to find a better one.

The following are required to run the app:
PR 1.3
Headphones

I have a dpendancies problem which i dont know how to solve. If you install the app fapman shows that the app has no dependancies listed inspite the fact that i have : at the control file. Does anyone know something? (Dont worry about this, if you have PR 1.3 installed there wont be any problem).

I also work on an other app (propably release it tommorow) called "T-CONTROL" (transmitter control) which is curently just a gui/front-end of fmtx_client. In future it will have a push button that will automatically scan and set the transmitter to the first empty frequency found and will not require headphones (sounds nice :D). I have a question about that (might be dumb but i did not find the answer): how do i include si4713.h header at http://www.mjmwired.net/kernel/Docum...nux/si4713.txt :D?

I know that you will ask me to upload it on extras-devel but i really dont know how and i will do it when i find some more time (i have a lot of homework and tests to do :()

Thanks to:
*pycage for various reciever questions (i have been bombarding him with questions since 2-September-2010 :D)
*SubCore for qt related help
*MohammadAG for packaging and other help
*billybobjones for the icon

NOTE: THE POSSITION OF THE HEADPHONES DIERCTLY AFFECTS THE RESULTS, TRY NOT TO HAVE THEM LIKE A SKEIN/BALL.

***CHANGE-LOG***
0.9.1
*Intial release

0.9.2
*Changed icon

0.9.3
*Scanning process is paused if headphones are removed during scanning process
*Extensive scan searches for emptier frequencies
*Some other fixes

Here are some screenshots:

Hi,

I don't know if you're using QProcess to run fmtx_client but I actually wrote a clone of fmtx_client using the Qt libraries (OK, I lie slightly: I use GLib to parse argv and argc. libkde and the qwt libraries come with option parsers implemented in native C++ but GLib comes with Maemo ;))

I don't know if it'll help you or not, but anyway:

Code: http://slexy.org/view/s2uQQMEpEo
Project file: http://slexy.org/view/s20jGlgKW9

One mistake in the code, however: rds_ps and rds_text should be g_freed after they're done with.

I don't know myself, sorry, but it seems that it implements the V4L interface for external control, have you tried that?

Euh..finally this application is free?? yay i'm Joking! Thanks for this dude!!!

This is one of the best compliments to the N900s media player. Thanks a bunch.

I ve been waiting for this. Thanks man. I ll give it a try.

Here's an icon I slapped together, if this is acceptable let me know and I'll send you a PNG in the size you would need.

Yes, its acceptable. Why not? Its definitely better than mine :).

English is not my native tongue so may be I didn't understant all that you said. Your app all to scan frequencies.

Is it possible to make an app that allow N900 to send a "RDS Eon" code to the car receiver. the goal is to establish a synchronisation between the N900 and the receiver to change frequency at the same time. Indeed, when i drive in surburbs there is not a lot of empty frequencies. Then I have to change manually frequency on N900 and my car receiver. It's not easy when you drive :)

Re: [ANNOUNCE] (QT) E.F.F. Empty Frequencies Finder app!
 

I dont know if its possible (actually i have never heared such thing) but i will make some google search and learn, sounds a very good idea :).

Thanks. i think FM transmitter is very pleasant to use when you're static. when you're driving is not easy. In paris you have a lot of stations. Use FM Transmitter is useless because each 10Mhz you have one radio. Then there are also a lot of interferences.

Nokia N900 have a RDS Decoder. May be an "AF" function (refer to RDS AF). All cars receiver have a RDS AF function. It's easy to say but I think Nokia N900 should send a code in the FM transmission to tell the receiver to synchronize with it.
