Johnny Five Plugin with etherport on arduino mega (wiznet5100)

---

wondering if someone has any experience in such a setup?

@djazzz Yes, I have it up and running

Which sketch should i flash on the mega 2560?

and do you consider it stable?

This deppends on the definition of “stable”

My setup runs flawlessly since months. However, there is one major issue I see, which lies in the “johnny-five” framework itself, or even deeper in the design of “firmata”: It is not possible to fully resynchronize the peers after connection-loss. If the connection between pimatic and the mega fails, it is possible to re-establish the transport connection, but the higher layer communication is in an inconsistent state then most of the time. I am currently investigating this to find a better soluution - part of which is also discussed as part of the johnny-five community.

Why does my setup run flawlessly? Basically, because the Mega and the Raspberry Pi are connected to the same switch. So, there is no connection-loss which you may experience if you Wifi, for example.

is there continuously data exchange between pimatic johnny-five and the arduino?
Even when nothing happens?

My suggestion is to use StandardFirmataEthernet. To gest started the easiest is to use the Arduino IDE, but of course you can also get evereything setup with toolchain on Linux.

Updating Firmata in the Arduino IDE - Arduino 1.6.4 and higher

If you want to update to the latest stable version:

1. Open the Arduino IDE and navigate to: Sketch > Include Library > Manage Libraries
2. Filter by “Firmata” and click on the “Firmata by Firmata Developers” item in the list of results.
3. Click the Select version dropdown and select the most recent version (note you can also install previous versions)
4. Click Install.
