Get the sample rate for the usrp device. If you are starting from scratch, or simply want to start with a fresh new installation of Linux, then please follow the instructions and recommendations in this section. Sign up using Email and Password. Several other alternate installation methods are also discussed. An example of where or how to use this automatic triggering: Make the install prefix writable by you as a user. The USRP should respond to the ping requests.

There should be a way to just build libudev. It also provides much uhe flexibility in upgrading and downgrading versions, and allows the user to modify the code and create customized versions, which could possibly include a patch or other bug-fix. Returns daughterboard TX ID, subdev name and spec, serial, and antenna.

Part of this is to better support Android development work in GNU Radio, but there are other use-cases where people find it useful to build static applications for easier distribution and configuration control of systems. You will probably need to set the sub-device specification as well I don’t see this in your code anywhere. Don’t worry, everything you need is installed where you need it. In summary, any given signal on a device using a direct conversion architecture has two paths for TX and two paths for RX.


Please follow the steps below. When this flag is enabled, gnurado build both the shared and static libraries. Gnurafio halted, the average value will be held constant until the user re-enables the automatic correction or overrides the value by manually setting the offset. At this point, GNU Radio should be installed and ready to use. This page was last modified on 29 Novemberat Notice the use of “-Wl,-whole-archive -luhd -Wl,-no-whole-archive’.

Perform write on the user configuration register bus. It it enables an easy way to customize the location of the installation, and to install multiple UHD versions in parallel, and switch between them. Not all commands are affected by time. The problem comes when you directly reference one of these variables.

UHD – Ettus Knowledge Base

These only exist if the user has implemented custom setting registers in the device FPGA. Created using Sphinx 1. We make use of the pmt:: The value is complex to control both I and Q.

At this point, connect the USRP to the host computer. Running it verifies that all the libraries can be found, and gnuraeio the GNU Radio run-time is working. So instead, we provide access functions for these variables. Used for timed transceiver tuning to ensure tuning order is maintained. This sets the method of time synchronization, typically a pulse per second or an encoded time.


One of the biggest issue that you run into with static libraries is in dealing with global variables. The following is my make file.

Building and Installing the USRP Open-Source Toolchain (UHD and GNU Radio) on Linux

Typical options for source: Some of those libraries I am not using but the problem persists when I include them gnuradlo. We have recently been working to support building and using static libraries for all GNU Radio components, which therefore means static libraries for our different dependencies as well. Oh, but wait, no it doesn’t.

The automatic correction subtracts out the long-run average. One of the other nice things that Martin did when adding static library support to libuhd was also provide CMake settings that we can use. Linking in the whole archive forces all static variables in that archive to be initialized at runtime before anything else is called. On Ubuntu, the second problem is difficult because we need libusb
