2020-12-18Fix hackrf receive hangs by checking before each lock waitv0.2.3Adrian Chadd1-2/+10
Fix receive path hangs if another thread closes down the hackrf receive whilst this buffer receive function is waiting to be woken up. Now: * Sleep for up to 100ms each time waiting for the cond to be kicked; * Check whether streaming is still enabled each time rather than only when the function is entered. This fixes hangs where consumers like gqrx via gnuradio will do a stop_rx/start_rx very quickly to change something, and the buffer receive path is waiting for a buffer.

2020-08-09HackRF: fix hackrf_source signednessv0.2.2Mike Walters1-1/+1
The LUT changes in 2e7d343fed inadvertently started interpreting samples as unsigned. This change puts it back to signed (and fixes an outdated comment). Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-03HackRF: convert _lut to float[] to reduce size by a factor of 256Wim Lewis1-16/+9
Similar to commit 33a8d1c for RTL-SDR, this uses two lookups in a 256-element LUT instead of one lookup in a 65536-element LUT, which saves a bit of CPU cache. It also eliminates a dependency on the host's byte ordering. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-02A lot of Boost functionality is available in C++11. Since GNU Radio is ↵Clayton Smith1-2/+2
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). Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-02-16hackrf: replace boost::assign with C++11Clayton Smith1-10/+1
Since GNU Radio is gradually replacing Boost with C++11, it seemed worth doing that for the HackRF blocks I was working on. This change removes all usage of boost::assign. From: Clayton Smith <argilo@gmail.com> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2020-02-16hackrf: allow transmit/receive switchingClayton Smith1-360/+45
To allow switching between transmit and receive mode within a single flow graph, I've followed the model used by the BladeRF: I factored common code into hackrf_common.cc and hackrf_common.h, and created a "_devs" map there to keep track of which devices have been previously opened. Shared pointers are used to track how many source & sink blocks are using a particular device. Because some properties (center frequency, sample rate, bandwidth, RF amplifier state, bias tee) are shared between receive and transmit, the blocks defer setting these until receiving or transmitting is started. That way a source and sink can safely use different values for these properties, and the correct values are set during T/R switching. Because the HackRF driver and/or hardware does not seem to fully transmit all samples sent to it, the code adds some silence to the end of transmissions to ensure all samples are transmitted. I've also replaced boost with C++11 code where possible. From: Clayton Smith <argilo@gmail.com> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

2015-05-27hackrf: introduce bias=0|1 and bias_tx=0|1 parametersDimitri Stolnikov1-0/+18
... to support antenna/phantom power via a new device argument "bias" (to match Airspy's existing bias power syntax). 0=disable and 1=enable. I also added a device argument to control bias power at transmit time. I named this option differently - "bias_tx" - to avoid accidentally enabling bias power in transmit mode when an LNA may be attached in an input amplifier configuration.

2014-02-11osmosdr/rtl/miri/hackrf: use 15 buffers by defaultDimitri Stolnikov1-1/+1
folowing rtl-sdr commit 89f73b183f2dac9c0dd75beca4cf2f77f20c4a36 So far we had 32 * 256KB which was a bit overkill, 15 are more than enough. 15 was chosen instead of 16 because at least on Linux there seems to be a system-wide limit of 63 transfers (when they are 256KB large), so 4 dongles can be used on a single machine without lowering the default transfer number.
2013-10-25hackrf: implement device discoveryDimitri Stolnikov1-5/+49
Unfortunately libhackrf still doesn't offer a way to enumerate devices *or* to open a specific device by index or it's serial number. Thus we have implemented a rather hack-ish way to detect the presence of a device by trying to open it and closing right after that.

this prevents a regression with early firmware who did not have 8M rate but 5M instead. they both had 10M, so we use this as default.

This allows a block to enable an associated driver to begin transfering data just before we start to execute the scheduler. The end result is that this reduces latency in the pipeline when dealing with audio devices, usrps, etc.
