2014-05-04uhd: implement stream arguments for sample formatDimitri Stolnikov2-26/+85
cpu_format: sc8, sc16, fc32, fc64 otw_format: sc8, sc16 fullscale: specifies the full-scale amplitude when using floats. peak: specifies a fractional sample level to calculate scaling with the sc8 wire format. example: osmocom_fft -a uhd,otw_format=sc8,fpga=usrp1_fpga_4rx.rbf -s 16M
2014-05-03uhd: catch exceptions from dc offset & iq imbalance settersDimitri Stolnikov2-17/+41
since dc offset / iq imbalance is not implemented for recent USRPs this might cause undesired behavior in GRC. As a workaround we do not pass them to the caller but print them to the stderr.
2014-04-16uhd: pass through only the requested number of channelsDimitri Stolnikov2-2/+4
B210 USRP appears as a 2-channel device by default. We prevent weird application behavior by restricting the number of connected channels to the value given via nchan= argument (1 by default).

2014-03-10bladerf: Fixed bug in cached device cleanupJon Szymaniak1-4/+10
A couple issues were present in bladerf_common::close, which caused entries in the _devs list (our "device cache") to not be removed. This would result in a stale device handle being used upon attempting to reopen the device. Two issues were associated with this bug: - The weak_ptr expired() conditional was incorrect; the logic was inverted. - The list item removal and iterator increment was done incorrectly and would result in a crash after the first item was fixed.

2014-02-16bladeRF: RXVGA2 range is [0, 30]Jon Szymaniak1-1/+1
While the RXVGA2 gain can technically go up to 60 dB, the LMS6002D datasheet recommends it be clamped to 30dB. libbladeRF clamps to a max of 30dB, so there's no use in setting max to 60 dB here.
2014-02-16bladerf: Added 'verbosity' and 'loopback' device parametersJon Szymaniak2-0/+67
The 'verbosity' parameter may be used to increase or suppress output from libbladeRF. The available log levels are, in order of decreasing verbosity are: verbose, debug, info, warning, critical, silent The 'loopback' parameter may be used to put the bladeRF into one of the supported loopback modes. The valid modes are listed below. Their descriptions may be found in the libbladeRF documentation: bb_txlpf_rxvga2, bb_txlpf_rxlpf bb_txvga1_rxvga2, bb_txvga1_rxlpf rf_lna1, rf_lna2, rf_lna3
2014-02-11osmosdr/rtl/miri/hackrf: use 15 buffers by defaultDimitri Stolnikov5-8/+8
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.
2014-02-09airspy: add support for AirSpy wideband receiverDimitri Stolnikov11-1/+855
Requires https://github.com/airspy/host Usage example: osmocom_fft -a airspy The following named gain stages are available: LNA: 0 to 15, step 1 MIX: 0 to 15, step 1 IF: 0 to 15, step 1 At the moment the gains are not in dB but gain indices internal to R820t tuner.

2014-01-13bladerf: Removed sign extension and masking of samplesJon Szymaniak1-10/+17
This is no longer required as of FPGA v0.0.1, and has been removed to remove some unnecessary computation on samples.

2014-01-13bladerf: Use rational sample rate functionsJon Szymaniak4-69/+48
libbladeRF provides accessors for rational sample rates, which the integer sample rate functions use under the hood. Therefore, there's no need to check if the requested rate contains a fractional portion and switch between the two sets of functions.

2013-12-22rfspace: add support for RFSPACE SDR-IQ and SDR-IPDimitri Stolnikov10-1135/+1749
Usage example: osmocom_fft -a sdr-iq=/dev/ttyUSB0 osmocom_fft -a sdr-ip=host[:port] osmocom_fft -a netsdr=host[:port][,nchan=2] The following named gain stages are available: SDR-IQ: ATT: -20 to +10 dB, in 10dB steps SDR-IP: ATT: -30 to 0 dB, in 10dB steps The ftdi_sio driver is being used for SDR-IQ. It creates a character device of the form: crw-rw---- 1 root dialout 188, 0 Dec 19 22:14 /dev/ttyUSB0 To be able to open the device without root permissions add yourself to the "dialout" group or do a "chmod 666 /dev/ttyUSB0" after pluggin in.

2013-11-01netsdr: replace boost asio sockets with native bsd socketsDimitri Stolnikov2-17/+223
until we find out what's exactly interfering with fosphor when using python based flowgraphs (osmocom_fft). c++ flowgraphs are not affected.
2013-10-30bladerf: Don't reload the FPGA unless the force-reload param is setJon Szymaniak1-8/+17
2013-10-30bladerf: Moved initializations to bladerf_common.c, misc. cleanupJon Szymaniak5-256/+216
Common parameter handling has been moved into bladerf_common::init(). The buflen parameter is now in units of samples, not bytes. This deviates from the other gr-osmosdr items. However, with the requirement that buffers be in multiples of 1024 samples, this makes specifying this parameter a bit easier. The user shouldn't need to know we're operating on SC16Q12 values under the hood, and have to calculate accordingly. To avoid confusion when both a bladeRF source and sink are in a flow graph a [bladeRF source/sink] prefix has been added to output. Error number have been replaced with bladeRF string representations of these error values. Firmware flashing has been removed. The bladeRF-cli or bladeRF-flash tools are the preferred route for firmware upgrades.
