Nodered a la RPi
Install/Upgrade. Aquesta comanda fa tota la feina:
$ bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)
Autostart on boot
$ sudo systemctl enable nodered.service reinicio $ service nodered status ● nodered.service - Node-RED graphical event wiring tool Loaded: loaded (/lib/systemd/system/nodered.service; enabled; vendor preset: Active: active (running) since Tue 2018-06-26 14:08:18 UTC; 4min 55s ago
Des del portàtil:
I ara ja puc fer les primeres proves. Si vull treballar amb els pins GPIO de la RPi, m'he d'acabar de mirar el document, però ha de ser fàcil.
Proves amb el node JSON, funcions, i d'altres coses
He fet proves, i a vegades no és tan evident. El projecte que estic fent es pot exportar per tal de poder reproduir-lo en un altre servidor de Node-Red:
