Dimitri Stolnikov afd56f4b5a hackrf: implement BB lowpass filter control 
To use the default (automatic) bandwidth filter selection, this should
be set to 0.
 2013-04-15 23:36:55 +02:00
Dimitri Stolnikov 448206b2d2 hackrf: implement full control for RF/IF/BB gain stages 
the following named gain stages are available:

RF: MGA-81563, switchable 0 or 14dB
IF: MAX2837 LNA, 0 to 40dB in 8dB steps
BB: MAX2837 VGA, 0 to 62dB in 2dB steps

Dimitri Stolnikov f5670788fc hackrf: add support for HackRF devices through libhackrf 
features:

- gain control for LNA & VGA
- frequency error correction
- automatic baseband filter
- up to 20M sampling rate

limitations:

- no DC offset correction implemented (yet)
- no RX preamplifier control (disabled by default)
- high sampling rates may not work on slow machines

Dimitri Stolnikov e415d843c7 add support for software IQ imbalance correction 
this functionality depend on the gr-iqbal blocks developed by Sylvain
Munaut and is a compile time dependency:

Dimitri Stolnikov ad2e5523cb fill up missing radio channel(s) with gaussian noise 
This is being done to prevent the application from crashing
due to a gnuradio bug. The GR maintainers have been informed.

Dimitri Stolnikov 2878501284 add support for MSi2500 based DVB-T dongles through libmirisdr 
this has been tested with analog modes only and still has to be
verified with the usual digital modes for proper implementation.

Dimitri Stolnikov c51b04ee74 don't throw exceptions inside a gr_hier_block2 ctor 
This avoids throws in ctor of gr_hier_block2, as gnuradio is unable to
deal with this behavior in a clean way. The GR maintainer Rondeau has
been informed.

Dimitri Stolnikov 86ec5d3b73 add if gain setter API for rtl-sdr 
and OsmoSDR devices

Observations lead to an useful gain
range from 15 to 30dB, a value of
24dB is used by default.

Dimitri Stolnikov 3ea0b38810 introduce device discovery api 
This API allows to acquire a list of devices connected to the host and
creates an argument string ready to be passed to a source object for
cunstruction.

Each device_t entry contains a "label" entry, which holds the generic
device name which may be shown to the user for device selection.

For certain radio hardware extended entries ("name", "serial", "type")
may be available to make bijective device addressing possible.

The argument string for target types "rtl_tcp" and "file" might be
constructed using the osmosdr::device_t class facilities.

Example:

 #include <osmosdr_device.h>
 #include <osmosdr_source_c.h>

osmosdr::devices_t devs = osmosdr::device::find();

BOOST_FOREACH(osmosdr::device_t &dev, devs) // try to create each dev
  osmosdr_source_c_sptr src = osmosdr_make_source_c(dev.to_string());

Dimitri Stolnikov f94d8da48e rtl_tcp: add initial component files 
For use with the rtl_tcp utility acting as a spectrum server.

The "empty" rtl_tcp= device hint might be used to connect to rtl_tcp
running on local machine.
