USBtin CAN Gateway
Introduction
The USBtin Can Gateway is an efficient and inexpensive way to connect a Can bus to Domoticz.
All information about hardware, firmware, etc... are available on the original site : https://www.fischl.de/usbtin/
This gateway is supported by domoticz as a usb to serial device, so the USBtin.cpp class offer a way to communicate on a bus Can using a high level layer.
Actually, only Multibloc V8 protocol is supported, but possibilities are limitless (CanOpen, J1939, Nmea, etc...), any developer can implement any protocol !
Instructions
Insert the USBtin gateway in a USB port before hardware creation in Domoticz.
If all is ok, you will see multiple choice in the "port serie" field. The gateway may appear with "/dev/ttyACMx" or under "/dev/serial/by-id/USB-Microchip-Technology..."
Actualy, as stated above, only Multibloc_V8 protocol is supported.
So only the switch named "Multibloc_V8" is usable in the hardware settings:
When hardware starts, here is the type of log we should see:
Currently, the gateway is always start with 250KB/s in Active mod.
For developper only: Developper who would like to integrate new protocol and do what he wants,will have to add som additional settings in the class USBtin.cpp.
