[PATCH] gr-osmosdr: fix hackrf_source signedness
by Mike Walters 05 Aug '20

05 Aug '20

The LUT changes in 2e7d343fed inadvertently started interpreting samples as unsigned. This change puts it back to signed (and fixes an outdated comment).

[PATCH] gr-osmosdr: Fix YML block generation
by Mike Walters 28 Jul '20

28 Jul '20

This fixes the template syntax that removes a set of variables from sink blocks. Previously, this was causing NameErrors when trying to generate a flowgraph containing a sink block.

Osmocom scheduled outage on *2020-07-19 9am CEST*
by Harald Welte 19 Jul '20

19 Jul '20

There is an urgent need to migrate our most important public infrastructure to a new server, and I will be doing that on *Sunday, July 19 2020*, starting about 9am CEST. The migration involves redmine (main osmocom.org website), jenkins, gerrit, git, and cgit. In theory, the migration should be quick. I would expect (significantly) less than one hour of downtime. However, we all know Murphys law. Services not affected are mail (including mailman lists), ftp, dns. So in case of doubt, we can still use mailing lists to communicate. In case anyone urgently needs osmocom source code on Sunday morning during the downtime: There are public mirrors available on github.

[PATCH] librtlsdr: Allow device specification with an USB path
by Alexander Motzkau 20 Jun '20

20 Jun '20

I'm using a Raspberry with two similar devices but different antennas. Specifying the device via index didn't work, because the enumeration of devices changed from time to time. Therefore I implemented functions to give a USB path instead. This path looks the same as the Linux kernel uses (eg. "4-1.2") and contains the USB bus and port numbers. I'll hope you'll find my patch acceptable. Best Regards, Alex Add functions to query devices via path, and path from a device. The path is formatted similar to Linux USB device names (bus number, hyphen, ports separated by dots, eg. "4-1.2"). --- include/rtl-sdr.h | 25 +++++++ src/convenience/convenience.c | 10 +++ src/librtlsdr.c | 121 ++++++++++++++++++++++++++++++++++ 3 files changed, 156 insertions(+) diff --git a/include/rtl-sdr.h b/include/rtl-sdr.h index d64701e..e6ce33a 100644 --- a/include/rtl-sdr.h +++ b/include/rtl-sdr.h @@ -49,6 +49,31 @@ RTLSDR_API int rtlsdr_get_device_usb_strings(uint32_t index, char *product, char *serial); +/*! + * Get device index by USB path string. + * + * The path string has the format "bus-port.port..." + * (i.e. the bus number, followed by a hyphen, then + * followed by the port numbers separated by dots). + * + * \param path path string of the device + * \return device index of the device with the given path + * \return -1 if no matching device was found. + */ +RTLSDR_API int rtlsdr_get_index_by_path(const char *path); + +/*! + * Get the USB path. + * + * NOTE: The buffer should provide space for at least 32 bytes. + * + * \param index the device index + * \param buf buffer where the path will be written + * \param len size of the buffer + * \return 0 on success + */ +RTLSDR_API int rtlsdr_get_device_path(uint32_t index, char *buf, size_t len); + /*! * Get device index by USB serial string descriptor. * diff --git a/src/convenience/convenience.c b/src/convenience/convenience.c index 00cc2cc..55f82e2 100644 --- a/src/convenience/convenience.c +++ b/src/convenience/convenience.c @@ -268,6 +268,16 @@ int verbose_device_search(char *s) device, rtlsdr_get_device_name((uint32_t)device)); return device; } + /* does string match a path */ + if (s2[0] == '-') { + i = rtlsdr_get_index_by_path(s); + if (i >= 0) { + device = i; + fprintf(stderr, "Using device %d: %s\n", + device, rtlsdr_get_device_name((uint32_t)device)); + return device; + } + } /* does string exact match a serial */ for (i = 0; i < device_count; i++) { rtlsdr_get_device_usb_strings(i, vendor, product, serial); diff --git a/src/librtlsdr.c b/src/librtlsdr.c index 0146298..e3f03d7 100644 --- a/src/librtlsdr.c +++ b/src/librtlsdr.c @@ -1414,6 +1414,127 @@ int rtlsdr_get_device_usb_strings(uint32_t index, char *manufact, return r; } +static void get_device_path(libusb_device *dev, char *buf, size_t len) +{ + uint8_t port_numbers[16]; + int port_entries; + int i, count; + + count = snprintf(buf, len, "%d-", (int)libusb_get_bus_number(dev)); + if (count < 0) { + buf[0] = 0; + return; + } + else if ((size_t)count >= len) { + buf[len-1] = 0; + return; + } + + len -= count; + buf += count; + + port_entries = libusb_get_port_numbers(dev, port_numbers, sizeof(port_numbers)/sizeof(port_numbers[0])); + if (port_entries < 0) + return; + + for (i = 0; i < port_entries; i++) { + count = snprintf(buf, len, i ?

[PATCH] Replace some Boost classes with C++11
by argilo＠gmail.com 31 May '20

31 May '20

From: Clayton Smith <argilo(a)gmail.com> A lot of Boost functionality is available in C++11. Since GNU Radio is moving away from Boost, it probably makes sense to do so in gr-osmosdr as well. This change removes all usage of boost::mutex, boost::mutex::scoped_lock, boost::unique_lock, and boost::condition_variable. It also removes usage of boost::shared_ptr and boost::weak_ptr outside of block definitions (which must continue to use Boost until GNU Radio 3.9). --- include/osmosdr/pimpl.h | 6 +++--- lib/airspy/airspy_source_c.cc | 2 +- lib/airspy/airspy_source_c.h | 9 +++++---- lib/airspyhf/airspyhf_source_c.cc | 2 +- lib/airspyhf/airspyhf_source_c.h | 9 +++++---- lib/bladerf/bladerf_common.cc | 15 +++++++-------- lib/bladerf/bladerf_common.h | 11 +++++------ lib/device.cc | 6 +++--- lib/freesrp/freesrp_common.cc | 3 +-- lib/freesrp/freesrp_common.h | 3 ++- lib/hackrf/hackrf_sink_c.cc | 4 ++-- lib/hackrf/hackrf_source_c.cc | 4 ++-- lib/miri/miri_source_c.cc | 6 +++--- lib/miri/miri_source_c.h | 9 +++++---- lib/osmosdr/osmosdr_src_c.cc | 6 +++--- lib/osmosdr/osmosdr_src_c.h | 9 +++++---- lib/rfspace/rfspace_source_c.cc | 6 +++--- lib/rfspace/rfspace_source_c.h | 15 ++++++++------- lib/rtl/rtl_source_c.cc | 6 +++--- lib/rtl/rtl_source_c.h | 9 +++++---- lib/sdrplay/sdrplay_source_c.h | 7 ++++--- lib/soapy/soapy_common.cc | 4 ++-- lib/soapy/soapy_common.h | 5 +++-- lib/soapy/soapy_sink_c.cc | 4 ++-- lib/soapy/soapy_source_c.cc | 4 ++-- 25 files changed, 85 insertions(+), 79 deletions(-) diff --git a/include/osmosdr/pimpl.h b/include/osmosdr/pimpl.h index e1985b4392..3a99994879 100644 --- a/include/osmosdr/pimpl.h +++ b/include/osmosdr/pimpl.h @@ -18,7 +18,7 @@ #ifndef INCLUDED_OSMOSDR_PIMPL_H #define INCLUDED_OSMOSDR_PIMPL_H -#include <boost/shared_ptr.hpp> +#include <memory> /*! \file pimpl.h * "Pimpl idiom" (pointer to implementation idiom). @@ -39,7 +39,7 @@ * \param _name the name of the pimpl class */ #define OSMOSDR_PIMPL_DECL(_name) \ - struct _name;

[PATCH] fcd: restore support for FUNcube Dongle and Pro+
by argilo＠gmail.com 31 May '20

31 May '20

From: Clayton Smith <argilo(a)gmail.com> Support for the original FUNcube Dongle used to live in GNU Radio's gr-fcd module, which was removed in version 3.8. As a result, gr-osmosdr lost support for both FUNcube Dongle and FUNcube Dongle Pro+. The gr-fcdproplus out-of-tree module subsequently added support for the original FUNcube Dongle, meaning that it now supports both types. As a result, FUNcube support can easily be restored in gr-osmosdr. The #ifdefs are no longer required, since everything is in a single module now. --- CMakeLists.txt | 1 + cmake/Modules/FindGnuradioFCDPP.cmake | 27 +++++++++++++++++++++++++++ lib/CMakeLists.txt | 8 ++++++++ lib/fcd/CMakeLists.txt | 21 ++++----------------- lib/fcd/fcd_source_c.cc | 18 +----------------- lib/fcd/fcd_source_c.h | 13 ++----------- 6 files changed, 43 insertions(+), 45 deletions(-) create mode 100644 cmake/Modules/FindGnuradioFCDPP.cmake diff --git a/CMakeLists.txt b/CMakeLists.txt index 7a2cf9df3d..14a9ddda7f 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -176,6 +176,7 @@ find_package(LibHackRF) find_package(LibAIRSPY) find_package(LibAIRSPYHF) find_package(LibbladeRF) +find_package(GnuradioFCDPP) find_package(SoapySDR NO_MODULE) find_package(LibFreeSRP) find_package(Doxygen) diff --git a/cmake/Modules/FindGnuradioFCDPP.cmake b/cmake/Modules/FindGnuradioFCDPP.cmake new file mode 100644 index 0000000000..f81fe8aa41 --- /dev/null +++ b/cmake/Modules/FindGnuradioFCDPP.cmake @@ -0,0 +1,27 @@ +if(NOT GNURADIO_FCDPP_FOUND) + pkg_check_modules (GNURADIO_FCDPP_PKG libgnuradio-fcdproplus) + find_path(GNURADIO_FCDPP_INCLUDE_DIRS NAMES fcdproplus/api.h + PATHS + ${GNURADIO_FCDPP_PKG_INCLUDE_DIRS} + /usr/include + /usr/local/include + ) + + find_library(GNURADIO_FCDPP_LIBRARIES NAMES gnuradio-fcdproplus + PATHS + ${GNURADIO_FCDPP_PKG_LIBRARY_DIRS} + /usr/lib + /usr/local/lib + ) + +if(GNURADIO_FCDPP_INCLUDE_DIRS AND GNURADIO_FCDPP_LIBRARIES) + set(GNURADIO_FCDPP_FOUND TRUE CACHE INTERNAL "gnuradio-fcdproplus found") + message(STATUS "Found gnuradio-fcdproplus: ${GNURADIO_FCDPP_INCLUDE_DIRS}, ${GNURADIO_FCDPP_LIBRARIES}") +else(GNURADIO_FCDPP_INCLUDE_DIRS AND GNURADIO_FCDPP_LIBRARIES) + set(GNURADIO_FCDPP_FOUND FALSE CACHE INTERNAL "gnuradio-fcdproplus found") + message(STATUS "gnuradio-fcdproplus not found.") +endif(GNURADIO_FCDPP_INCLUDE_DIRS AND GNURADIO_FCDPP_LIBRARIES) + +mark_as_advanced(GNURADIO_FCDPP_LIBRARIES GNURADIO_FCDPP_INCLUDE_DIRS) + +endif(NOT GNURADIO_FCDPP_FOUND) diff --git a/lib/CMakeLists.txt b/lib/CMakeLists.txt index d04cb1d402..3199ef3d79 100644 --- a/lib/CMakeLists.txt +++ b/lib/CMakeLists.txt @@ -135,6 +135,14 @@ if(ENABLE_OSMOSDR) add_subdirectory(osmosdr) endif(ENABLE_OSMOSDR) +######################################################################## +# Setup FCD component +######################################################################## +GR_REGISTER_COMPONENT("FUNcube Dongle" ENABLE_FCD GNURADIO_FCDPP_FOUND) +if(ENABLE_FCD) + add_subdirectory(fcd) +endif(ENABLE_FCD) + ######################################################################## # Setup File component ######################################################################## diff --git a/lib/fcd/CMakeLists.txt b/lib/fcd/CMakeLists.txt index 146191f7ac..7a515c71fc 100644 --- a/lib/fcd/CMakeLists.txt +++ b/lib/fcd/CMakeLists.txt @@ -23,25 +23,12 @@ target_include_directories(gnuradio-osmosdr PRIVATE ${CMAKE_CURRENT_SOURCE_DIR} + ${GNURADIO_FCDPP_INCLUDE_DIRS} ) -if(ENABLE_FCD) - target_include_directories(gnuradio-osmosdr PRIVATE - ${Gnuradio-fcd_INCLUDE_DIRS} - ) - target_link_libraries(gnuradio-osmosdr PRIVATE - ${Gnuradio-fcd_LIBRARIES} - ) -endif(ENABLE_FCD) - -if(ENABLE_FCDPP) - target_include_directories(gnuradio-osmosdr PRIVATE - ${Gnuradio-fcdpp_INCLUDE_DIRS} - ) - target_link_libraries(gnuradio-osmosdr PRIVATE - ${Gnuradio-fcdpp_LIBRARIES} - ) -endif(ENABLE_FCDPP) +target_link_libraries(gnuradio-osmosdr + ${GNURADIO_FCDPP_LIBRARIES} +) list(APPEND gr_osmosdr_srcs ${CMAKE_CURRENT_SOURCE_DIR}/fcd_source_c.cc diff --git a/lib/fcd/fcd_source_c.cc b/lib/fcd/fcd_source_c.cc index 885d514787..744fa69553 100644 --- a/lib/fcd/fcd_source_c.cc +++ b/lib/fcd/fcd_source_c.cc @@ -142,18 +142,15 @@ fcd_source_c::fcd_source_c(const std::string &args) : std::cerr << "Using " << name() << " (" << dev_name << ")" << std::endl;

fl2k on rpi4: no more USB error
by Carl-Fredrik Enell 22 May '20

22 May '20

Dear all, I found that the fix for the USB issue on ARM systems has finally made it into the Linux kernel, 5.6.14 and 5.7-rc6. Today I installed the latest Manjaro 64 unstable mainline kernel on my rpi4 and made some quick tests with fl-wspr (https://github.com/tejeez/fl2k-tool) There are no more USB errors*, but I still get underflow errors at high sample rates. In my quick tests the maximum reliable sample rate was about 20 MHz when running in an X session with other programs. When I stopped the X server and ran in a text console I could go above 30 MHz without underflows. This means that the rpi4 is fine as an SDR transceiver for many purposes- but it would be nice to know if it is possible to tune the system for a bit higher sample rates! All the best SM2YHP Fredrik * Installed AUR package libosmo-fl2k-git to fix other USB device issues -- ------------------ Carl-Fredrik Enell Föraregatan 26B SE-98139 Kiruna +46705508256 -----------------
