Raspberry Pi web based rig control?

A while back my friend and I found hamlib, a development library designed to remotely control nearly any CAT/CIV capable transceiver or receiver.  It compiles and works just fine on the Raspberry Pi.

 Before-hand ensure you have these dependencies installed:  
 libltdl-dev or libltdl-devel or libtool-ltdl-devel (use yum/apt-get)  
 wget http://sourceforge.net/projects/hamlib/files/hamlib/1.2.15.3/hamlib-1.2.15.3.tar.gz  
 tar -xvzf hamlib*  
 cd hamlib*  
 ./configure  
 make  
 make install  
 ldconfig   

 


So we have been using SSH and hamlib to control a remote Icom 706.  We have been using speak freely to stream the audio.

I have been meaning to try and create a PHP/CGI web based front end for this.  Couple that with darkice and icecast for a way to stream audio to that browser.

There is network daemon version of rigctl that works like so:

rigctld -r /dev/ttyUSB0 -m 311 & 

Then control can be done via TCP port 4532:

 root@darkpi-ice:/# telnet localhost 4532  
 Trying 127.0.0.1...  
 Connected to localhost.  
 Escape character is '^]'.  
 f <---- I sent this and got back below:  
 1590000  

Here is a screen shot of my web control front end:

Here is the radio with the Raspberry Pi, USB sound input, USB TTL converter for CIV.
Basically a way to enable web based control of a radio with CIV.  Remi, F4ECW has some example PHP code for this that I snagged from a Yahoo group.  It also appears to have a start for remote fldigi.

Another good project would be to layout a small board with jumper selectable COR and PTT transistor configurations than can be interfaced to the Raspberry Pi GPIO.  So far I have just been bread-boarding this.

I just haven't had the time to create such art work and submit it to Far Circuits.


Again if anyone wants to beat me to the punch on either of this, please do.
