| | | | Add example to demonstrate and test SPI functionality.
* SPI: Implement SPI engine for x410Martin Anderseck2022-01-1312-15/+491
| | | | | Add SPI Core host implementation for x410 and a discoverable feature to make it accessible.
* rfnoc: Always clear response queue in ctrlport_endpointMartin Braun2022-01-131-16/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the behaviour of ctrlport_endpoint (the register interface for block controllers) to always check for an ACK after doing a poke or poll of any kind. Previously, the behaviour was to only check for an ACK if the policy was set that way, or if the user requested the ACK to be received. The problem with the former approach was that if many pokes were performed without ever requesting an ACK or a poll, the response queue would fill up without ever getting emptied, eventually draining the available heap space. Note that this is not a memory leak in the usual sense, as the response queue was correctly holding on to the response packets. With this change, ctrlport_endpoint::wait_for_ack() now receives a require_ack parameter. If it is false, the behaviour of wait_for_ack() is changed as follows: - If the response queue is empty, immediately return with an empty response payload object. - Otherwise, continue reading elements out of the response queue until it is either depleted (in which case the previous rule kicks in), or we find the ACK corresponding to the command previously sent out. Note that this replicates the corresponding behaviour in UHD 3 (see ctrl_iface_impl::wait_for_ack()).

* uhd: Fix non-standard function name macrosMartin Braun2022-01-127-14/+24
| | | | | | | | | | | | | | | | | Throughout UHD, we are using a random mix of __FUNCTION__, __func__, __PRETTY_FUNCTION__, and BOOST_CURRENT_FUNCTION. Note that the first two macros are non-standard (although many compilers understand them), and the last requires Boost. __func__ is available since C++11, but is not the best choice because the C++ standard doesn't require it to be of any specific value. We thus define UHD_FUNCTION and UHD_PRETTY_FUNCTION as portable macros. The former simply contains the undecorated function name, the latter the expanded function with full signature. As it happens, our currently supported compilers didn't have any issues using non-standard macros, so the main fix here is the removal of the Boost macros and the harmonization of the other macros.
* x300: Fix LED configuration for TwinRXMartin Braun2022-01-111-13/+53
| | | | | | | | | | | | | | The problem was that TwinRX has a special LED configuration (unlike most other daughterboards): Since it has two channels, it is possible to stream RX from both SMA ports. In that case, we would light up both LEDs in green (which was not happening, only one LED would light up, depending on which antenna was set last). This fixes the problem and turns on both LEDs when both channels are used, and both SMA ports are selected. Note that the reason for this issue was an incorrect porting of this code from UHD 3. There, we had separate LED ATR objects per channel.

* e3xx: Fix frequency queryingMartin Braun2022-01-101-2/+11
| | | | | | | The E3xx devices have one LO per TX/RX, respectively. That means when changing the frequency on channel 0, the frequency on channel 1 also gets changed. The code didn't track this change properly: When setting channel 1, channel 0's frequency didn't match.
* RFNoC: Fix DSP frequency accuracymichael-west2022-01-104-12/+26
| | | | | | | | | | The host code was calculating and programming a 32-bit value for the DSP frequency, but the DDS modules in the FPGA only use the upper 24-bits. This led to inaccurate frequency values being returned. This change corrects the resolution of the value on the host side so an accurate value is returned.

* rfnoc: Add atomic item size property for RFNoC blocksLars Amsel2022-01-1011-10/+232
| | | | | | | | | | | | | | | An RFNoC block (like the radio) might require a minimal number of items in each clock cycle, e.g. the radio has to process SPC (samples per cycle). Because data in RFNoC is transmitted and processed in packets, we have to make sure the items inside these packets are a multiple of the items processed in each cycle. This commit adds an atomic item size properties which is set by the radio and adapted by the streamers. The streamers adapt the SPP property of the radio block controller depending on the MTU value. This might lead to an SPP value which does not align with the SPC value of the radio block, hence we add a property resolver for the atomic item size.
* rfnoc: transport: Check if streamers are connected in send() and recv()Martin Braun2022-01-102-2/+40
| | | | | | | | | | | | | | | | This adds a check in send() and recv() whether or not the streamer is actually connected. If not, an exception is thrown with the message: [rx_stream] Attempting to call recv() before all channels are connected! or [tx_stream] Attempting to call send() before all channels are connected! The check is a single boolean flag check, but it does add a branch in our hot code. Since this event is unlikely, and only happens in badly configured apps, we will get some help from the CPUs branch prediction to reduce the additional cost of this check.
* uhd: Allow pass raw IQ data array to tone generatorLars Amsel2022-01-101-4/+15
| | | | | | | | Instead of calculating a tone from its parameter it is also useful to pass an precalculated signal to be played. This change modifies the __init__ to take an iq_data as parameter for the internal buffer and moves the generation of the tone from rate, frequency and amplitude into a class method. The streamer parameter was deleted (never used).
* e31x/e320: Amend LO-locked sensor namesMartin Braun2022-01-101-14/+17
| | | | | | | | | In UHD 3, we had two sensors names for LO lock on these devices: lo_lock, and lo_locked. The latter is the more standard, and is checked in examples like rx_samples_to_file. In UHD 4, the latter was removed without comment. This adds the sensor back again and also updates the documentation accordingly.
* host: multi_usrp: Merge set_tx_subdev_spec and set_rx_subdev_specLane Kolbly2022-01-101-99/+67

* rfnoc: ddc/duc: Improve variable name for _set_freq()Martin Braun2022-01-072-4/+4
| | | | | | | | As Github user johnwstanford points out, the DUC calls the argument 'input_rate', which is wrong (and was copy/pasted from the DDC code). By calling it dds_rate in both cases, we avoid such confusion. This commit only renames a variable. No changes whatsoever.

| | | | | | | | | - Referred to E310 as E3x0, but that's wrong. E320 has a different GPIO bank naming scheme. - Fails to mention N3x0. This change makes the page mostly device-agnostic (X410 GPIO control is still elsewhere). - The first example had a typo (wrong pin was selected in ATR example). - The second example added nothing, and was removed for clarity.

* uhd: nsis: Remove broken shortcuts in Windows installerAaron Rossetto2021-12-161-4/+0
| | | | | | | | The Windows UHD installer binary, generated by e.g. running the PACKAGE project in the Visual Studio solution generated by CMake, creates two shortcuts to utilities that are no longer included with the installer: the USRP2 card burner and USRP-N2xx net burner. This commit removes these defunct shortcuts.
* tools: Add check for SEP with ctrl enabled to rfnoc_image_builderLars Amsel2021-12-161-0/+13
| | | | | | | | | When creating RFNoC images at least one SEP needs to have ctrl enabled otherwise one will end up with a non-functional image. This commit adds a method to the image builder to do plausibility checks on the configuration. The only check done for now is to verify that there is at least one SEP with ctrl enabled.
* docs: Fix MathJax formulae renderingAaron Rossetto2021-12-161-1/+1
| | | | | | | | | | When a webpage is accessed via secure HTTP, and that webpage attempts to address active content via a non-secure URI, most modern browsers will block the loading of that content as a security precaution. In this case, the URI to the MathJax JavaScript rendering library was specified in the Doxygen configuration with an HTTP (i.e., non-encrypted) URI, thus preventing the browser from loading it and rendering formulae correctly.

* examples: Fix tx_bursts bandwidth/freq/gain reportingMartin Braun2021-12-161-11/+9
| | | | | | | | | | | | | This example would not specify a channel when querying the actual frequency/bandwidth/gain after setting it. When using the --channels options like this: tx_bursts --channels 1 --freq 1e9 [...] ...it would request the frequency of 1 GHz on channel 1, then query the frequency on channel 0 when reporting the "actual" frequency. Also removes some boost::format().
* docs: remove bmaptool instructions for writing filesystemsMatthew Crymble2021-12-141-3/+3
| | | | | | Due to a change in Mender, bmaptool is no longer supported for writing filesystem images. Currently, the only recommended method for writing a filesystem to an SD card is to use dd. The filesystem can still be updated in place using mender.
* host: Make radio_control constants an enumLane Kolbly2021-12-102-108/+82
| | | | | | | In C++, variables whose address are taken must be defined somewhere. PERIPH_BASE had no such definition, so on some compilers/systems caused a linker error. This commit switches to using enums to prevent this happening again in the future.
* tests: Add replay-back-edge testMartin Braun2021-12-091-0/+44
| | | | | | | | | This tests the following graph: DDC -> Replay -> DDC, where the initial and final blocks are the same (i.e., a loop). This could be useful for generating and capturing data with the same replay block while testing a block. Note that this test will fail if the edge consistency checks are buggy.
* rfnoc: Fix back-edge consistency checkMartin Braun2021-12-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On back-edges, no properties are forwarded, but properties must be consistent after property resolution. This breaks when the source edge on a back-edge has an edge property which the destination block does not. Consider the following graph: DDC -> Replay -> DDC where both instances of 'DDC' refer to the same block. Now, assume the first edge is declared a back edge (in principle, it shouldn't matter). The DDC block has an edge property `samp_rate` which the Replay block does not. Therefore, it can't forward this edge property to the Replay block's input edge property list. In the consistency check code, we don't check for the existence of edge nodes, because it is assumed edge properties where either forwarded, or aligned through some other manner. This leads to a property lookup failure. With this fix, we skip the consistency check for edge properties which don't exist on the destination node. This is safe because the destination block can not have a property resolver defined for undefined properties. This means the destination block can either: - Drop the property. In this case, there is no value in checking consistency. Even if we could forward edge properties on back-edges, they would always have the same value. - Forward the property. In that case, the consistency check would happen elsewhere in the graph where there's no back-edge.
