RS485 CAN HAT [RESOLVED]

[yiannis]

Hi,

I saw how cheap this [https://thepihut.com/products/isolated-r...spberry-pi] was and I thought that I could replace the USB-RS485 adapter for more or less the same money and have a HAT rather than a USB device hanging of my RasPi and an NMEA2000 interface for future expansion.

I sorted out the CAN side of things but I cannot understand how to enable/connect the RS485 ports. Anybody has done it? I tried adding this to /boot/config.txt

Code:

dtparam=spi=on
dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25,,spimaxfrequency=1000000
dtoverlay=sc16is752-spi1,int_pin=24

But I got a conflict at the 'Check System' applet.
   

Any ideas?

TIA
