USRP Hardware Driver (UHD™) Software
Welcome to the UHD™ software distribution! UHD is the free & open-source
software driver and API for the Universal Software Radio Peripheral (USRP™) SDR
platform, created and sold by Ettus Research.
UHD supports all Ettus Research USRP™ hardware, including all motherboards and
daughterboards, and the combinations thereof.
For technical documentation related to USRP™ hardware or UHD system
design, check out the [UHD and USRP Manual](http://files.ettus.com/manual/).
That is where you can find
help on how to
[build UHD from source](http://files.ettus.com/manual/page_build_guide.html) on
different platforms, development guidelines and reference documentation as well
as device usage guidance.
Additionally, be sure to check out the Ettus Research
[FAQ](http://www.ettus.com/kb/detail/frequently-asked-questions), and the
[Knowledge Base](http://www.ettus.com/kb) for useful application notes and
## OS Support
UHD is primarily developed on Linux, but we also test and support the following
* Linux (Fedora and Ubuntu)
* Mac OS X (Intel)
* Windows 7
Other operating systems will most likely work, too, but are not officially
UHD can be used to build stand-alone applications with USRP™ hardware, or with
third-party applications. Some common toolkits / frameworks are:
* [GNU Radio](http://gnuradio.org/)
* [Amarisoft LTE eNodeB](http://www.amarisoft.com/?p=amarilte)
The source code for the user-space driver.
The source code for all microprocessors in USRP hardware.
The source code for the UHD FPGA images. Note this is a git submodule,
if you are cloning the repository and want to modify the FPGA code,
you will need to run 'git clone --recursive' to automatically
populate this directory. Alternatively, you can run 'git submodule init'
followed by 'git submodule update' to populate it after cloning the
repository without '--recursive'.
Note that this subdirectory is very large, and not necessary for
building applications that link against UHD.
This contains the package builder for FPGA and firmware images.
We provide other tools to download image packages, the scripts in here
are mainly relevant for UHD maintainers and -developers.
Additional tools, mainly for debugging purposes. See the readme-file
in that directory for more details on the individual tools.
