Post-installation

Options:

To see a list of all the available options run:

memduinod -h

Running:

You can either run memduinod in a terminal, passing it any options you want. Example:

sudo memduinod --serial-port /dev/ttyUSB0 --update-interval 500

or you can run memduinod as a systemd service by first appending any options you want to the MEMDUINO_ARGS variable in /etc/memduino/args, and starting it with:

sudo systemctl start memduinod

If you also want memduinod to start at boot run:

sudo systemctl enable memduinod
