NMR Code

The software system comprises:

• A Xilinx Vivado project that yields a bitstream for the Red Pitaya FPGA
• A C server and startup script that runs on the Red Pitaya ARM
• A Python user interface that runs on a client PC.

The server and client parts are archived here, along with a gzipped bitstream.

Client deb: nmr_2.0_all.deb

Python environment

The client, pulsed_nmr.py requires Qt5 and matplotlib, and Python 3. The native versions on Ubuntu 22.04 are OK

Old note, from when Qt4/5 got mixed

Any Qt4 present will break it: could not find or load the Qt platform plugin "xcb". Here is an anaconda recipe, including removal of the Qt4 that matplotlib thinks it wants:

conda create --name nmr -c spyder-ide pyqt5
. activate nmr
conda install matplotlib
conda remove --force qt pyqt
