pi4

Raspberry Pi node pi4

This is a Raspberry Pi 3+ running Raspberry Pi OS (Debian Buster) with the latest VSCP daemon installed and among other things have a Frankfurt RS-232 module that connects to a CAN bus that is run to our kitchen on the upper floor of our house. Here there are some nodes that control a refrigerator and a fridge.

The Frankfurt RS-232 module is connected to the VSCP daemon with the level I/CANAL CAN4VSCP driver. The configuration file vscpd.json for the VSCP daemon looks like this
