2014-02-16bladeRF: RXVGA2 range is [0, 30]standaloneJon 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
2014-02-16osmosdr/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.
2014-02-16airspy: 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.

2014-01-26bladerf: 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.

2014-01-26bladerf: 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.

2014-01-26rfspace: 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.

2013-11-04netsdr: 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.
2013-11-04bladerf: Don't reload the FPGA unless the force-reload param is setJon Szymaniak1-8/+17
2013-11-04bladerf: 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.
2013-11-04bladerf: Moved no longer "common" items out of bladerf_commonJon Szymaniak6-61/+57
The gr_complex FIFO is no longer used on the TX side, so it doesn't really make sense to have it in bladerf_common. The associated items have been moved into bladerf_source, and some renaming has been done in bladerf_sink to tidy up. Pending further performance tests of the bladerf_source, the _fifo member (boost::circular_buffer) may need to be replaced.

2013-10-25hackrf: implement device discoveryDimitri Stolnikov2-6/+93
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.
