libsmu contains abstractions for streaming data to and from USB-connected analog interface devices, currently supporting the Analog Devices' ADALM1000. Building off of LibUSB for cross-platform operation, it offers the sourcing of repeated waveforms, configuration of hardware, and measuring of signals.
Python bindings are also provided in the form of the pysmu module. See instructions below for how to build them.
Conda and Anaconda are cross-platform package-management tools that generally focus around python but can support any language or package generally. You can find documentation on the libsmu conda package here .
Download the specific libsmu .deb package for your Linux distribution from the Releases section. Currently we are supporting Ubuntu 16, 18 and 20. The package name should start with libsmu and contain the OS version. Go to the folder you downloaded the package in and open a terminal, then run the following command:
analog@analog:~$ sudo apt install -f ./<libsmu_package_name>.debDownload the specific libsmu .pkg package for your MacOS distribution from the Releases section. Currently we are supporting MacOS 10.15, 11.0. The package name should start with libsmu and contain the MacOS version.
Open a terminal and run the following command which will install only the base library in /Library/Frameworks.
analog@analog:~$ sudo installer -pkg /path/to/<libsmu_package_name>.pkg -target /A different way to install libsmu on MacOS is by using the .tar.gz located in the Releases section. This will install the .dylib (libraries) into system paths (usr/local) and it will also install the smu CLI.
tar -xzvf <libsmu_package_name>.tar.gz --strip=3 -C /usr/localBased on this base library installation, you can install the Python bindings manually for the desired Python version. Check the Python section below or you can use the wheel packages provided in the official installer. Check out the next section:
If you want to install pysmu (the Python bindings for libsmu), you can download the specific wheel for your version. We provide python wheel packages for the following Python versions: py3.7, py3.8, py3.9, py3.10. You can download the .whl for your Python version from the official releases or use the ones provided on test.pypi.org (soon from the official pypi.org as well). On Linux:
# If you are installing from test.pypi.org:
analog@analog:~$ python3 -m pip install --index-url https://test.pypi.org/simple/ pysmu
# If you are installing the .whl downloaded from our official github release:
analog@analog:~$ python3 -m pip install pysmu-1.x.y-cp3x-cp3x-manylinux_2_24_x86_64.whlOn MacOS:
# If you are installing from test.pypi.org:
analog@analog:~$ python3 -m pip install --index-url https://test.pypi.org/simple/ pysmu
# If you are installing the .whl downloaded from our official github release:
analog@analog:~$ python3 -m pip install pysmu-1.x.y-cp3x-cp3x-macos_10_15_x86_64.whlPlease note that in order to use these bindings you need the core C++ library they depend upon. This is not packaged with the pypi release but you can install the latest release or the latest untested binaries from the master branch.

Install to build documentation
analog@analog:~$ brew install doxygenanalog@analog:~$ git clone https://github.com/analogdevicesinc/libsmu.git

Configure via cmake:
analog@analog:~$ mkdir build && cd build
analog@analog:~$ cmake .. -DBUILD_PYTHON=ONCompile:
analog@analog:~$ makeIf -DBUILD_PYTHON=ON (from the above options) is specified, this step will also install the Python Bindings using the Python version detected at the CMake configuration step.
analog@analog:~$ sudo make installDoxygen-based documentation is available at https://analogdevicesinc.github.io/libsmu/.
This can also be built locally if enabled using the CMake option mentioned above. After make is run, the generated documentation files can then be found in the html subdir of the build directory.
The Google Test framework is used to run various streaming tests. Make sure it's installed on the host system and then use the following to build and run tests:
analog@analog:~$ cmake -DBUILD_TESTS=ON ..
analog@analog:~$ make checkNote that at least one device should be inserted to the system for the checks to run properly.
Python Bindings are enabled by default and can be disabled using the CMake option mentioned above.
Note that this will build only one version of Python for the first supported implementation it finds installed on the system. To build them for other versions it's easiest to build them manually via the setup.py script in the regular python manner if libsmu has already been built and/or installed on the host machine.
analog@analog:~$ git clone https://github.com/analogdevicesinc/libsmu.git
analog@analog:~$ cd libsmu/build
analog@analog:~$ cmake -DBUILD_PYTHON=ON .. #this will generate a setup.py file in the current directory
analog@analog:~$ python3 -m build #this will create .whl files in a dist/ directory
# the .whl files can then be installed using "pip install"By default, libsmu is installed into various directories inside /usr/local which implies that the runtime linker cache often needs to be regenerated, otherwise runtime linking errors will occur.
Regenerate runtime linker cache after install:
analog@analog:~$ sudo ldconfigIf the same errors still happen, make sure the directory the libsmu library is installed to is in the sourced files for /etc/ld.so.conf before running ldconfig.
In addition, the udev rules file (53-adi-m1k-usb.rules) is installed by default to give regular users access to devices supported by libsmu. Udev has to be forced to reload its rules files in order to use the new file without rebooting the system.
Reload udev rules files:
analog@analog:~$ sudo udevadm control --reload-rulesFinally, for python support on Debian/Ubuntu derived distros users will have to export PYTHONPATH or perform a similar method since hand-built modules are installed to the site-packages directory (which isn't in the standard search list) while distro provided modules are placed in dist-packages.
Add pysmu module directory to python search path:
$ export PYTHONPATH=/usr/local/lib/python3.7/site-packages:${PYTHONPATH}
Note the command will have to be altered for targets with different bitness or python versions.
On Windows, it's easiest to use the provided installers, libsmu-setup-x86.exe and libsmu-setup-x64.exe that install either 32 or 64 bit support, respectively. During the install process options are provided to install drivers and Visual Studio development support.
Note that after v1.0.3, libsmu Windows installers no longer provide the option to install Python bindings. The process for installing pysmu on Windows is similar to the one described above for MacOS and Linux.
