After changing the source code of an example UHD application, (base UHD directory)/share/uhd/examples Modifying a Sample Program in Linux Any sample program can be modified and recompiled. Windows installations typically place UHD in C:/Program Files(x86)/UHD, and the examples are found in: Locating the UHD Examples In typical Linux installations, the UHD path is /usr/local/share/uhd/. The source code for the example programs is also provided for developers that want to gain a better understanding of various UHD API features. Example programs are provided with UHD to allow basic functional testing of one or more USRP devices. UHD is currently used in several development environments including GNU Radio, LabVIEW, Matlab, Simulink and other custom frameworks. UHD provides an application programming interface (API), which provides access to various functions of the USRP including synchronization, sample streaming and configuration.
#Examples of note taking software driver
The abstraction provided by the driver allows substantial portability between USRP products. UHD allows development on multiple operating systems including Linux, Windows and MacOS.
#Examples of note taking software software
UHD is a driver developed by Ettus Research and is compatible with all USRP (Universal Software Radio Peripheral) software defined radios. Introduction This document will provide information on code examples provided with the USRP Hardware Driver (UHD). Application Note Examples Provided with the USRP Hardware Driver
