OpenMarine

I have a can and an rs485 device that both have SPI support. At the moment they talk through USB but I'd rather have it hardwired.
I cannot find out how to configure SPI support in the current openplotter.

Any experience or advice would be most welcome.

Seems possible to emulate tty serial interfaces on spi devices. Anyone?
