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, LLC.
UHD supports all Ettus Research USRP™ hardware, including all motherboards and daughterboards, and the combinations thereof.
The UHD Homepage, through which you can find installation instructions, documentation, and further information, is the primary source of UHD documentation and "Getting Started"-type guides.
For technical documentation related to USRP™ hardware or UHD system design, check out the UHD Manual.
If you are looking for API documentation, check out the following resources:
Additionally, be sure to check out the Ettus Research FAQ, and the Knowledge Base for useful application notes and tutorials.
UHD is primarily developed on Linux, but we also test and support the following operating systems.
- Linux (any distribution)
- Mac OS X (PPC and Intel)
- Windows 7/Vista/XP
UHD can be used to build stand-alone applications with USRP™ hardware, or with third-party applications. Some common toolkits / frameworks are:
host/
The source code for the user-space driver.
firmware/
The source code for all microprocessors in USRP hardware.
fpga/
The source code for the UHD FPGA images.
images/
This contains the package builder for FPGA and firmware images.
