rs-jerry-gnuradio

This repository is meant to be an example on how to use the rs-jerry-driver generally in a more elaborated way as well as offering a ready-to-use gnuradio block for people who want to further use the IQ samples provided by the MSR4 in gnuradio.

Hence this repository requires the rs-jerry-driver to be installed on the system globally and to work properly.

This repository is based on bkarl's gnuradio-dpdk repo.
