My approach: * build your grc chart from GNU Radio Companion and generate the .py file * edit the py file and import pygpio * play with the RPi4 GPIO in your python script.
See attached script, with a python server included in the Python script to control an RF switch from a GNU Octave TCP/IP client talking to the Python TCP/IP server. I am presenting this approach to hardware control at http://jmfriedt.free.fr/sdra_radar.pdf JM -- JM Friedt, FEMTO-ST Time & Frequency/SENSeOR, 26 rue de l'Epitaphe, 25000 Besancon, France June 18, 2020 9:40 PM, "Da Fy" <diver86...@gmail.com> wrote: > Hi All, does anyone have an example of how to control GOIO lines on the RPi4 > from within a GRC > flowgraph.
