Thanks Dirk,

meanwhile, I have come one step further:
I am still using the Modbus RTU Slave device on the Arduino side "Arduino Coupling" from https://revolutionpi.com/tutorials/downloads.

Hello Dirk,

To establish a connection with an Arduino, I did the following.

For the wiring, the Revpi and Arduino are connected directly with an USB cable.
For a Modbus RTU Slave device on the Arduino side, I download the sample sketch "Arduino Coupling" from the download page (https ...

Hello everyone,

I am using a RevPi Core S8 with Buster V10.

I would like to use an Arduino to read existing sensors via i2c. Both boards are connected via USB and the Arduino is integrated via a virtual Modbus RTU master.
This procedure was outlined in https://revolutionpi.de/blog/maker-herz ...

Vielen Dank!

Hallo,

Wäre es möglich, auch an einem RevPi Core die Anzahl der USB-Anschlüsse mit einem USB-HUB zu erweitern?

Danke und Gruß
