* cal: Add pwr_cal containerMartin Braun2020-04-1710-1/+1071
| | | | | | | This is a cal container for all types of power cal (RX or TX) that rely on a single, overall gain value. Includes Python API.
* lib: utils: interpolation: Add bilinear interpolationMartin Braun2020-04-172-1/+186
| | | | | | This allows to treat a std::map<KeyType<std::map<KeyType, ValueType>> as a set of x-y coordinates, and bilinearly interpolate a z-value given four x/y pairs.
* Revert "cmake: Add ability to pass CXXFLAGS to CMake environment"Martin Braun2020-04-151-3/+0
| | | | This reverts commit 49ca8112c2777fcc4b81eff72ce59fb40fa0024d.
* uhd: Create shell script to replace CMake's package_sourceSteven Koo2020-04-151-0/+108
| | | | | | | This script replaces CMake's package_source implementation to allow for pulling in the firmware, fpga, mpm, host, and tools folders. This builds two tarballs, one with and one without the firmware, fpga, and mpm folders.
* utils: usrp_burn_mb_eeprom: Avoid EEPROM write in read only casesteviez2020-04-151-17/+19
| | | | | | The usrp_burn_mb_eeprom previously updated the EEPROM at the end of the script, regardless of whether any values were actually specified for write. This skips the EEPROM write for read only usage.
* libusb: Remove deprecation warnings for libusb_set_debugMartin Braun2020-04-151-1/+14
| | | | | | | | | | | Starting with 1.0.22, libusb considers libusb_set_debug() deprecated. This replaces said call with libusb_set_option(), conditionally on the libusb version. This has no effect on the execution, but will remove some compiler versions, and make this code more future-proof. Note that Ubuntu 18.04 ships libusb 1.0.21, so this conditional code needs to remain until that version is deprecated and libusb version is bumped higher.
* examples: wavetable: Modify wave tables to ease power calculationsMartin Braun2020-04-151-19/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing implementation would create a real signal for any type of signal (CONST, RAMP, SQUARE, and SINE), and then create the complex signal by simply delaying the Q value by a 90 degree phase. This had surprising results for all waveforms: - CONST waveforms would have a baseband value of ampl + j ampl, thus increasing the output power by 3 dB vs. what one would expect when setting an amplitude. It is now ampl + j * 0, and the power is ampl**2. This now makes the power consistent with SINE, which it was not, even though a const signal is a sine signal with a frequency of zero. - SQUARE waveforms would phase-delay the Q part, thus resulting in three power output levels (when both phases are zero, when both phases are ampl, and when one of them is zero and other is ampl). However, the square signal is useful for watching it in the scope, and there, it helps if the power is predictably either high or low within the selected frequency. The Q value is now always zero. - RAMP waveforms had the same issue and were also resolved by setting Q to zero. - SINE signals were fine, although the implementation used sin + j cos to calculate a complex sine, not cos + j sin according to Euler's formula. To make this wavetable more useful with absolute power settings, the changes mentioned above were implemented. The dBFs power of CONST and SINE can now be calculated by using ampl**2, SQUARE by using (ampl**2)/2, and RAMP by solving the integral over a ramp from -1 to 1.

* fpga: rfnoc: Add option to sample sideband info at start of packetWade Fife2020-04-141-58/+117
| | | | | | | | The axis_data_to_chdr block previously only sampled the sideband information at the end of the packet. This adds a parameter that controls if the sideband information should be sampled at the beginning of the packet or the end of the packet. In the former case, large internal packet buffers are not required.
* fpga: tools: Add -voptargs=+acc to ModelSim GUIWade Fife2020-04-141-1/+1
| | | | | | Add -voptargs=+acc to the default options when running vsim. This option enables debug command access to objects in the design, which is generally needed for debugging in the GUI.
* fpga: core: Add chdr_update_length functionWade Fife2020-04-141-0/+21
|
* fpga: lib: Add AXI-Stream splitter (axis_split)Wade Fife2020-04-142-0/+129
| | | | | | | The axis_split module takes a single AXI-Stream input and duplicates it onto multiple AXI-Stream outputs. This block correctly handles the somewhat tricky flow-control logic so that the AXI-Stream handshake protocol is honored at all top-level ports.

* fpga: tools: Option to check for full Vivado versionHumberto Jimenez2020-04-141-0/+24
| | | | | | | | | | | | | | | | | | | | | | This commits enables the FPGA build infrastructure to require a very specific Vivado version, all the way to the patch level. Vivado typically has the following version format: Year.release.update_patch This commit enables setupenv_base.sh to optionally look for the environment variable VIVADO_VER_FULL, which should contain the full Vivado version in the format specified above. Vivado is directly used to retrieve the installed version, returning an error if the requested version is not found. Example in setupenv.sh (which calls setupenv_base.sh): VIVADO_VER=2019.1 VIVADO_VER_FULL=2019.1.1_AR73068 The setupenv.sh script will setup Vivado 2019.1, but it will also verify that both Update 1 and patch AR73068 are installed.
* utils: log: fix logging race conditionmattprost2020-04-141-1/+3
| | | | | | | It was possible that output to cout would become interleaved inside of the uhd log messages. Signed-off-by: mattprost <matt.prost@ni.com>
* rpclib: Remove some warnings from object.hppMartin Braun2020-04-141-0/+12
| | | | | This removes -Wmaybe-uninitialized and -Wclass-memaccess from this file when using gcc.
* b200: Add a prop tree node usb_versionMartin Braun2020-04-141-0/+1
| | | | | At /mboards/0/usb_version, we can now read back an int. It's either 2 or 3, depending on what we're using.
* tests: migrated rfnoc block tests to dedicated subdirectorymattprost2020-04-136-381/+455
| | | | | | | | This separates the rfnoc block tests into files for each specific block. This was done to improve the readability of these files and declutter the tests directory. Signed-off-by: mattprost <matt.prost@ni.com>
* docs: Add stream and transport args documentationAaron Rossetto2020-04-132-6/+210
| | | | | | Add some additional documentation to the Configuration Devices and Streamers and Transport Notes pages regarding stream arguments and their use.
* multi_usrp: Approximate legacy behaviour for recv_async_msg()Martin Braun2020-04-133-13/+34
| | | | | | | | | | | | | When using multi_usrp with an RFNoC device, the previous behaviour was to throw an exception when calling recv_async_msg() so users would know they're not supposed to call it (calling tx_stream::recv_async_msg is preferred). However, this breaks too many existing applications. Instead, we keep a weak pointer to the streamer, the same way that older devices do, and query the async message from that. This means that calling recv_async_msg() when there are multiple streamers can lead to unexpected behaviour, but that's a general issue with multi_usrp::recv_async_msg() and this way, the RFNoC devices now behave like older devices do.
* multi_usrp_rfnoc: Manually pass sample rate to ddc/ducsteviez2020-04-135-0/+38
| | | | | | | | | | | | | | This adds (and calls) methods to manually pass radio block sample rate to the input/output properties of the ddc/duc during creation of the multi_usrp_rfnoc object. The ddc/duc require this information in order to return valid, possible output/input sample rates in get_rx_rates()/get_tx_rates(). Before, the ddc/duc wouldn't have this rate until the rfnoc_graph had been connected and committed, which happens in get_rx_stream()/get_tx_stream(). Thus, this fixes an issue where a user was unable to query possible sample rates prior to specifying a sample rate and creating a stream.
* multi_usrp_rfnoc: Fix get_rx/tx_rates()steviez2020-04-131-12/+10
| | | | | This replaces incorrect code with the proper function calls to retrieve the range of possible sample rates.

* lib: Properly do reset routines in client_zeroMartin Braun2020-04-091-2/+6
| | | | | The current reset routines write a '1' twice for reset, instead of '0' then '1' (resets get triggered on a rising edge).
* fpga: e31x: Update constraints to avoid timing issuesWade Fife2020-04-081-6/+6
| | | | | | | Xilinx changed the way [all_registers -edge_triggered] is treated such that set_max_delay constraints that use it can cause segmentation and cause clocks to not be propagated to all endpoints. Changing to [all_ffs] avoids this potential issue.
* tests: Fix client_zero_test flush bit testMartin Braun2020-04-081-6/+12
| | | | | A test to check the address was using a & instead of a %, resulting in a -Wtautological-compare.
* uhd: mpm: Query prefs per-device for multi-device queriesLane Kolbly2020-04-083-6/+16
| | | | | | | If a user specifies a multi-device query, such as "serial0=1234,serial1=4321", we have to look up the preferences for each device. To minimize the impact to non-x400 devices, I simply push the get_usrp_args call down into mpmd_impl and mpmd_find.
* uhd: Add missing include guardsLane Kolbly2020-04-083-0/+6
|
* uhd: Replace include guards with pragma onceLane Kolbly2020-04-08270-1077/+272
| | | | | Pragma once is the more modern version of include guards, eliminating any potential problems with mistyping include guards. Let's use those.
* uhd: Add fuzzy serial number checkingLane Kolbly2020-04-086-1/+83
| | | | | | | | | We have integer 32-bit serial numbers for MPM devices, for example "1234abcd". For serial numbers which have less than eight digits, e.g. "123abcd", a user may feel inclined to prefix this number with a 0 when they are searching for devices, e.g. "0123abcd". This change makes it so that specifying "0123abcd" will match a device with serial number "123ABCD".

* uhd: Add quotes around test environment variablesLane Kolbly2020-04-071-1/+1
| | | | | | | On systems which have spaces in the environment variables, such as $PATH, attempting to run the generated test scripts will throw an error about a bad variable name. Adding quotes around the values prevents this error.

* uhd: math: Add interpolation.hppMartin Braun2020-04-0713-52/+208
| | | | | | | | - Moves linear_interp from cal to utils - Moves the interp_mode enum class to interpolation.hpp - Adds three interpolation methods for maps: at_interpolate_1d(), at_nearest(), at_lin_interp() - Adds unit tests

* utils: cal: Remove boost usage from usrp_cal_utils.hppMartin Braun2020-04-021-3/+0
| | | | | There were spurious boost includes left in here after applying 7ad64600f and a1f96194.
* cmake: Add ability to pass CXXFLAGS to CMake environmentAjith Saya2020-04-021-0/+3
| | | | CMAKE_CXX_FLAGS will now respect $CXX_FLAGS.
* uhd: paths: Harmonize around XDG Base Directory specificationMartin Braun2020-04-029-60/+159
| | | | | | | | | | | | | | | | | | | | | | Up until now, we completely ignore the XDG specification. This commit does the following to change that: - It uses XDG_DATA_HOME and XDG_CONFIG_HOME for cal and config data, respectively. - If config data is in ~/.uhd/uhd.conf, that is still accepted, but if it conflicts with $XDG_CONFIG_HOME/uhd.conf, it is ignored and a warning is displayed - The default location for cal data is thus ${HOME}/.local/share/uhd/cal on Unix, and %LOCALAPPDATA%\uhd\cal on Windows. This is a change in location! - The UHD_CONFIG_DIR environment variable was confusingly named and is now removed. It provided an alternative location than the home directory. The same purpose is now much better served by XDG_DATA_HOME and XDG_CONFIG_HOME. The specification can be found here: specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
* rfnoc: Use multichannel register interface for RFNoC blocksmattprost2020-04-024-54/+61
| | | | | | | | Allows RFNoC blocks to perform register peeks and pokes on blocks with multiple channels without having to worry about handling register address translation every time. Signed-off-by: mattprost <matt.prost@ni.com>
* rfnoc: Add multichannel register interfacemattprost2020-04-024-5/+480
| | | | | | | | | | | This utility class implements the register access methods of reg_iface but adds built-in address translation features for consecutive instances of an RFNoC block. The register peek and poke methods accept an extra 'instance' parameter which is used to calculate the absolute address for the register access. This can be used for accessing registers for the different channels of a multi-channel block (i.e. Radio, DDC, DUC, etc). Signed-off-by: mattprost <matt.prost@ni.com>
* utils: cal: Enable "ignore cal file" option for DC and IQ cal toolsMartin Braun2020-04-021-5/+5
| | | | | | | | | | | The utilities uhd_cal_rx_iq_balance, uhd_cal_tx_iq_balance, and uhd_cal_tx_dc_offset now add the flags to ignore cal files. Otherwise, the utility would load existing cal data before generating new cal data. Note that this is not a huge problem, because the cal coefficients get overwritten during the cal process, but is unnecessary disk I/O. This commit also happens to remove all boost::format uses within usrp_cal_utils.hpp.
* utils: Add convert_cal_data utilityMartin Braun2020-04-023-0/+107
| | | | | | | | | This will convert cal data files based on CSV to the new binary format. In most cases, running ./convert_cal_data.py is sufficient.
* uhd: cal: Use usrp::cal::database instead of CSV filesMartin Braun2020-04-026-200/+229
| | | | | | | | | Now that we have cal::iq_cal and cal::database, there's no need to manually wrangle CSV files for calibration data. This commit replaces all CSV operations with cal::database calls and uses cal::iq_cal as a container. CSV files can still be read, but are considered deprecated.
* uhd: cal: Add iq_cal calibration data container classMartin Braun2020-04-0217-1/+760
| | | | | | | | This class can be used to store calibration coefficients for the X300 DC offset and IQ imbalance calibration. Note: This also modifies Doxyfile.in to not document files generated by flatc.
* uhd: Add calibration container classMartin Braun2020-04-023-0/+68
| | | | | | | This adds uhd::usrp::cal::container, which serves as a base class for calibration data. It also provides the interp_mode enum class which can be useful for future calibration classes.
* fpga: tools: Add support for .sdc in VivadoPaul Butler2020-04-021-0/+3
| | | | | | viv_utils.tcl will now read files with the .sdc suffix using the read_xdc Vivado command. This is especially useful when I/O timing constraints in the FPGA and CPLD need to depend on a common constant.
