Introduction =============== This program attempt to mimic the sdrxx server created by Moe WHEATLEY in order to provide SDR-IQ with a network interface compatible with that of more sophisticated radio from RFSPACE. Alas the sdrxx server source code resulted unfeasible to port to Linux, but was invaluable as reference for write A special mention deservers Ken N9VV that put his radio, Linux computer and Internet connection to my disposal in order to develop and test this software. 1. Build ======== In order to compile this program and CuteSDR, you need to install the libftdi support and cmake: sudo apt-get install libftdi-dev cmake subversion # Debian /Ubuntu sudo rpm install libftdi-devel cmake subversion # RH/Fedora/OpenSuse After that you can extract the svn co https://cutesdr.svn.sourceforge.net/svnroot/cutesdr/branches/iw0hdv/linux/trunk/ cutesdr-lx Next compile with the following command: cd cutesdr-lx mkdir build cd build cmake ../ make -j4 sudo make install 2. Run ====== In order to run CuteSDR you have to remove from your system the standard Linux kernel FTDI driver; this is feasible at run time: sudo rmmod usbserial ftdi_sio Next check that the radio is correctly linked to the system: lsusb .... Bus 006 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC .... If everything is fine, open a terminal window and start the server: siqs ------ ------ SDR-IQ server for Cute SDR ------ ------ libftdi version ------ ------ (C) 2012, Ken N9VV && Andrea IW0HDV interfaces = 2: lo - 127.0.0.1 eth0 - 192.168.10.1 SRXXX STARTED: size 56 Press q to exit. Listening for TCP connections on port 50000 socket: 6 Last, run CuteSDR from another terminal window, and into the menu Setup->Network press "Find SDR" push button or manually insert the network data. The auto discovery proceudre works only if the CuteSDR and the server are placed on the same LAN (broadcast domain). Please not that the server is not yet completed with all the features: e.g. the discovery messages is only partially supported. cutesdr-1.0.5/siqs/cutesdrsrv.sh0000755000175000017500000000074011711273721016653 0ustar bottomsbottoms# # Example script for test the 'Bent pipe' concept. # Alas it is not fully working because the I/Q data messages coming out from the radio # have to be redirected into a separate UDP pipe. # # # interface="/dev/ttyUSB0" echo "Setting the $interface to 230400 b/s......" stty -F $interface 230400 cs8 -cstopb -parity -icanon min 1 time 1 echo "Listening on tcp/50000, please start CuteSDR......" socat tcp-l:50000,reuseaddr,fork file:$interface,nonblock,waitlock=./tty0.lock cutesdr-1.0.5/siqs/logger.h0000644000175000017500000001001111716037373015536 0ustar bottomsbottoms/* (C) 2012 Claudio Scordino No license on original code, see http://retis.sssup.it/~scordino/code/logger.html */ #ifndef LOGGER_H #define LOGGER_H #include #include #include #include #include /// Comment this line if you don't need multithread support #define LOGGER_MULTITHREAD const int DBG_ERROR = 0; const int DBG_WARN = 1; const int DBG_DEBUG = 2; #ifdef LOGGER_MULTITHREAD #include #endif /** * \brief Macro to configure the logger. * Example of configuration of the Logger: * DEBUG_CONF("outputfile", Logger::file_on|Logger::screen_on, DBG_DEBUG, DBG_ERROR); */ #define DEBUG_CONF(outputFile, \ configuration, \ fileVerbosityLevel, \ screenVerbosityLevel) { \ Logger::getInstance().configure(outputFile, \ configuration, \ fileVerbosityLevel, \ screenVerbosityLevel); \ } /** * \brief Macro to print log messages. * Example of usage of the Logger: * DEBUG(DBG_DEBUG, "hello " << "world"); */ #define DEBUG(priority, msg) { \ std::ostringstream __debug_stream__; \ __debug_stream__ << msg; \ Logger::getInstance().print(priority, __FILE__, __LINE__, \ __debug_stream__.str()); \ } #define XDEBUG(p, code) { \ if (Logger::getInstance().enabled(p)) { \ code ;\ } \ } /** * \brief Simple logger to log messages on file and console. * This is the implementation of a simple logger in C++.
