Hello guys,
I bought a RGB LCD from Waveshare and I would like to know if anyone alredy use it with node-red ? I didn't find any thnigs about it.
I would like to use it with node and not use python execute node if possible 
thanks for help
It is, I believe, an I2C connected display? If so, you need to drive it using GPIO. I assume you are using a Pi? If so, your options may be somewhat limited. Many of us don't use the Pi for GPIO but rather use low-cost ESP or Arduino MCP's. ESP devices especially since they are WiFi enabled and so are very easily connected to MQTT.
As @TotallyInformation says there is most likely support for this device in various EPS firmware's, and connecting this way prevents any accidental damage to your pi.
If you need to connect directly to the pi then you could do some digging on NPM or GitHub for NodeJS drivers, I found these for example which may or may not be compatible, but are the kind of thing you need to be looking for.
