IQEngine Workshop Marc Lichtman
Plugins OpenAPI Spec REST interface between IQEngine and plugins Can also be used to call plugins from whatever software you want A way to send our plugins IQ samples and params, and get back results https://github.com/IQEngine/IQEngine/blob/main/plugins/plugins_openapi.yaml
Exercise: Run a Local Plugins Server sudo apt update sudo apt install uvicorn ffmpeg libsm6 libxext6 python3-pip -y git clone https://github.com/IQEngine/IQEngine.git cd iqengine/plugins/src pip install -r requirements.txt uvicorn plugins_api:app --reload Use iqengine.org for now Open a recording, enable the time cursors on the left, then run whatever plugin you want Try editing src/lowpass_filter/lowpass_filter.py (e.g. pass_zero=False)
GNU Radio Based Plugins -Prep You need the python running the plugins server to see GNU Radio s python install Not always easy You can test by trying to run a local GNU Radio plugin (e.g. fm_rx_gnuradio) Alternatively, you can run the plugin server locally with Docker 1. Install docker (or docker desktop if you re using WSL) 2. cd iqengine/plugins 3. docker build -t plugins_image. 4. docker run -dit -p 8000:8000 --name plugins_container plugins_image 5. docker ps should show one container running 6. Stop with docker stop plugins_container and delete with docker rm plugins_container. 7. SSH into container with docker exec -it plugins_container /bin/bash
GNU Radio Based Plugins -Creation Copy the directory lowpass_filter_gnuradiousing a new name Make sure your flowgraph works in GRC with a File Source or SigMF Source Disable all GUIs, set flowgraph to no-gui mode (use null sink at the end) Generate the python flowgraph Copy the flowgraph definition code into the plugin python code, using the lowpass_filter_gnuradio as an example Replace the File Source with ZMQ Sub like in the example Replace the null sink with ZMQ Pub like in the example
