Integration with host other than a RPi - mikewindlake - 2024-02-13
I'd like to use an existing controller board I have to integrate NMEA 2000. Is there a spec for the communication to the MacArthur HAT?

MacArthur HAT communicates by SPI using a MCP2518FD chip. There is a driver for this chip in Raspberry OS.
this could be a good point to start:

Ok, I see from the schematic it's just routing to pins 10-13. SPI that's easy. Thanks
