ok thanks!
maybe is possible to implement it in a mainwindow so you can do something else wile scanning!
I have found a solution so you can multitask after-all :):

***NEW-VERSION***

1.2.3
Added the chance to select if you want gui or not during scanning so you can multitask
Better scanning results
Some ui changes

it will be very usefull!
I will add that to the next version thanks to martin/pycage :)

Checks if headphones are pluged in, thanks to pycage....again :)
Fixed some "bugs"

Tested it and works fine, remeber to type "root" NOT "sudo gainroot"

WhiteWolf 2010-09-26 12:48
Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
I am using "type root"

PROMPT displays: "Nokia-N900: #"

I get the error message indicated.

Hmmm. I tested on my n900 again and it works fine. Can anyone else confirm what WhiteWolf is saying?

Supersimo88 2010-09-26 13:43
Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
i'm testing...
it works very well!

Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
@WhiteWolf

When you say the error message indicated you mean "Nokia-N900: #"? This is not an error, you must make it executable and then run it:
DO THIS:
open xterm
type:
mkdir /home/user/bin
mv /home/user/MyDocs/<the path of your download file>
chmod u+x /home/user/bin/EFF-1.3.0
root
/home/user/bin/EFF-1.3.0

You need to do the above only once. The next time you want to run the EFF, just type:
/home/user/bin/EFF-1.3.0

@WhiteWolf

I can confirm that the shell script is fine. Either you follow the instructions wrong or your n900 must have a problem.
At which folder did you download the file?

BLIZZARD 2010-09-28 19:02
Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
**NEW-VERSION***

1.3.1
Fixed percentage calculation (was passing 100 before)
Corrected some spelling mistakes (scaning -> scanning) :D

Hy I have the same problem like WhiteWolf

I did a debug run:
http://pastebin.com/sSANspyY

I didn't let the program run until end I just exit after some time

Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
Indent your code!
Making debs is easy, hit me up with a PM if you have any problems :)
When you make a deb though you'll have to use sudo, so you should figure out why sudo gainroot doesn't work, prefix dbus and zenity lines with run-standalone.sh

i will change that line with copyright (a friend of me told me to write that..nonsense). I will butify the script :).

MohammadAG 2010-09-29 15:44
Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
Uh, does it matter? The kernel module is responsible on creating those files, not your script.
cat: can't open '/sys/class/i2c-adapter/i2c-3/3-0022/fm_rssi': No such file or directory
Your script tries to read that file ^ which doesn't exist on the stock kernel (or kernels based on it)

When you turn on reciever these files are created automattialy. The script works fine on my n900. Tested 1.4.0 on my n900 and works with sudo gainroot too.

Not really, which kernel are you on?
Code:
Nokia-N900:/sys/class/i2c-adapter/i2c-3/3-0022# fmtx_client -p1
Usage:
------
-f<uint>    Set frequency (in kHz)
-s<string>    Set RDS station name
-t<string>    Set RDS info text
-p<uint>    Turn fmtx on (1) or off (0)

Current settings (Frequencies in kHz):
--------------------------------------
version=1
frequency=107500
freq_min=76000
freq_max=107900
freq_step=100
state=enabled
rds_ps=Nokia 
rds_text=
Nokia-N900:/sys/class/i2c-adapter/i2c-3/3-0022# ls
bus        modalias  name      power      subsystem  uevent

BLIZZARD 2010-09-29 16:03
Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
Ffmtx_client is for controlling transmitter. I said that when you turn on reciever, these files are created automatically. Try opening FM RADIO app and you will see that the files will be created :)
I had power kernel installed but i flashed my n900 a week ago.

Re: [ANNOUNCE] E.F.F. Empty Frequencies Finder, shell script program with gui!
 
@WhiteWolf and others i think i solved you problem, pleas test the new version and post if its working or not

**NEW-VERSION***

1.4.2
Added more comments, beautyfied more the script
Prefixed zenity, thanks to MohammadAG :)
Corrected an expr issue
Now you can run EFF with root **AND** sudo gainroot!!!

EFF-1.4.2 http://www.mediafire.com/?5l0ngxbuja1rqw8

The file gets created on a stock N900 kernel when the bcm2048_radio kernel driver gets loaded. You need to have the n900-fmrx-enabler package installed to make this work, though. The N900 ships with the driver but it won't load unless you power up the i2c bus to the FM tuner on the Bluetooth chip. The n900-fmrx-enabler takes care of this.

Youre right :), i missed that, next version will check for zenity first.
EFF script is under the terms of the GNU General Public License.

This is the first time i am using this. Directly tried 1.4.2 and it said no zenity. Installed zenity from apt-get and ran the script. It gives me the headphones not found error.
