We use Boost. The Python API is currently part of master branch. In order to test the Python API, check out the master branch and build it like always. The examples are very simple, but concise. Documentation is currently pretty sparse. The methods on both classes are the same, and take the same arguments.
UHD Python API
No, it uses Boost. We didn't want to add another dependency to UHD i. It also doesn't require the C API. It serves an entirely different purpose. If you're using GNU Radio, you probably don't care about this. Short answer: No. Long answer: There are very few cases where it makes sense to mix these APIs, so no. However, this means that a TimeSpec from the Boost. Not yet, but it's in the pipeline.
We wanted to get the basics i. Overall, recv calls are pretty efficient if you've preallocated a NumPy array, because we can cast that to a straight pointer and also skip any type checking! However, consuming the data is limited by how fast you can handle that in Python. Other product and company names listed are trademarks or trade names of their respective companies.

Mar 21, Apr 23, Jan 28, Update branch for upcoming 3. Oct 15, Mar 10, On most Linux systems, there are packages called "python3-dev" or "python3-devel" that provide that functionality. Static linking on is unsupported on Windows.
UHD ships its own copy of PyBind11, in order to facilitate the access to that library, as it is not packaged for many operating systems, but also to lock down its version. The following two snippets are equivalent. A common type of Python-based SDR applications are those which produce or consume a limited number of samples.
For example, an application could receive a second's worth of samples, then do offline processing, print the result, and exit. The following snippet is an example of how to store 1 second of samples acquired at 1 Msps:.
This kind of API is particularly useful in combination with Jupyter Notebooks or similar interactive environments. From the Python wiki page on the GIL:. In CPython, the global interpreter lock, or GIL, is a mutex that protects access to Python objects, preventing multiple threads from executing Python bytecodes at once. To this end, users must ensure that the Python objects accessed by the listed functions are handled with care.
In simple, single threaded applications, this won't require any extra work. For example, if an application needs to call recv in one thread, and access the sample buffer from another thread, a synchronization method ie. Note that since UHD version 4. Installing on Windows Static linking on is unsupported on Windows.
Generated by 1.Commercial, academic, and military customers employ the flexible and reusable USRP hardware for research, wireless exploration, and field deployments. And since our embedded series USRPs house an internal GPP you can run these radios without the need of a host computer stand-alone mode.
UHD provides the necessary control used to transport user waveform samples to and from USRP hardware as well as control various parameters e. Figure 2 illustrates this concept:. For more information on our licensing policy, please contact info ettus. Users can make a choice if they prefer the latest development code, which is most feature-rich but can be unstable at times, or the more thoroughly tested code that does not include the latest development. Versioned releases e.
These bugfix releases are done off of the maint branch, which is where all the bugfix development happens. New feature development is done on the master branch. This branch should not be considered stable, even though we use continuous integration systems to monitor its state.
However, it is possible that APIs or dependency requirements change on the master branch. At the end of a feature development cycle, the master branch is frozen, and only bugfixes are accepted into the master branch.
Once the master branch is considered stable, the maint branch is reset to master, and a new versioned release is produced from the previous master branch. This is indicated by a major version number jump e. Major version releases occur times per year, and usually accompany new product releases. Aside from the maint and master branches, new feature branches are sometimes published temporarily to give insight into upcoming features, and earlier access to new development. Using a common software interface is critical, enabling code portability and, allowing applications to transition seamlessly to other USRP SDR systems when development requirements expand or new systems become available.
Hence, it enables a significant reduction in development effort by allowing you to preserve and reuse your legacy code. Installation packages for these platforms as well as instructions for building from source can be found here. Compatible with Python 2. It is not, in general, required for running UHD applications.
This is dependent on the distribution you are using, but most, if not all, of the dependencies should be available in the package repositories for your package manager.
See the Linux build instructions for more information. Use MacPorts to get the Boost and Mako dependencies. The dependencies can be acquired through installable EXE files.
Usually, the Windows installer can be found on the project's website. Some projects do not host Windows installers, and if this is the case, follow the auxiliary download URL for the Windows installer below. See the Windws build instructions for more information. For example, UHD 3. X and older won't work with Boost 1. Samples can be sent in a continuous stream as in figure 4a or in bursts, figure 4b.
In addition the user has the ability to specify when samples are received or transmitted by using built in burst and timed commands. This allows users to:. Different SDR configurations, waveforms, and applications require different sample rates. For example, a user may wish to monitor MHz of instantaneous RF bandwidth, but their host PC may only be capable of analyzing 20 MHz of real-time bandwidth. For this and other cases, UHD allows users to set various sample rates to meet their custom application.
Find additional information here. In summary, any given signal on a device using a direct conversion architecture has two paths for TX and two paths for RX. Because of slight differences due to variances in components, temperature, and other factors, the I and Q signal paths are subject to different conditions, thus altering the original signal that existed at initial capture.
When the phase or amplitude of either the I or Q get altered the results show up as signals not actually present in the original signal.Linux Notes: This is dependent on the distribution you are using, but most, if not all, of the dependencies should be available in the package repositories for your package manager. Use MacPorts to get the Boost and Mako dependencies.
Usually, the Windows installer can be found on the project's website. Some projects do not host Windows installers, and if this is the case, follow the auxiliary download URL for the Windows installer below.
The CMake path, e. The directory to which you extract libusb must not contain spaces. To install it using 'pip' on Windows, navigate to Python scripts folder, e. This will populate the fpga-src submodule inside the repository. You can also do this after cloning the repository by running these commands from the top level source directory:. We might also be publishing experimental feature branches which can then be found in the same repository.
All of our versioned releases are associated with tags in the repository. Additionally, configuration variables can be passed into CMake via the command line. The following common-use configuration variables are listed below:. Make sure that libuhd. However, this might not be true, e.
Note: You may not have permission to build the install target. You need to be an administrator or to run MSVC as administrator. Note: The default interface for editing environment variable paths in Windows is very poor.MASSIVE .45-70 HAND CANNON REVOLVER! (4K UHD)
Through OSX Staring in Hence, just use XQuartz from the get-go. Note that unless you experiment with using the Quartz interface to various graphical toolkits e. Apple provides a fully integrated development environment via their Xcode toolkit, which can be downloaded either via the App store or directly from Apple's Developer area depending on the version of OSX in use.
Xcode provides the compilers and related development tools needed to build or execute UHD and its dependencies. Once Xcode is installed, you must still install the Command Line Tools, which can be accomplished by running Xcode. You might be able to install the Command Line Tools in a terminal using. There are a number of background libraries and applications that must be installed from source or binary in order to compile or execute UHD; for a full list, see Build Dependencies.
MacPorts tends to be more up-to-date with respect to new releases, which can be both a blessing and a curse since sometimes new released are untested and result in build or runtime errors. NOTE: We highly recommended that all dependencies be installed via the same package manager! When issues arise, they are much easier to track down, and updating to newer versions of UHD as well as dependencies is much easier. NOTE: Other package managers e.
Please consult the specific package manager in use for how to do these commands properly; they will not be covered here. Installing UHD from source follows the standard cmake method as found in many places, with a few arguments to make sure cmake always finds the correct version of Python, and uses the desired compiler.
First, download the source code either via a release or via GIT.

I am running a modified version example included with the python-api branch, basically I am comparing usrp. There are probably a couple things wrong, but I am getting an overflow error out of sequence error:. I've plotted the results here:.
Here is a zoom-in of the modulated signal that I expect to see:. This is usually indicative of a network issue and not generally due to a bug in the UHD code. The other errors reported in the output i. I recommend testing UDP performance on your network. For further support, please consider posting on the usrp-users mailing list or contacting Ettus Support. On the same network using the python api capture I get dropped packets. Therefore, there seems to be a problem the python api.
I originally tested this python api when it was first released. We will look into the streaming performance of the Python API. Skip to content.
