I’m designing a circuit which requires dual RS422 for full-duplex COM.
It seems to me that if the W5500 allowed me to send data (point-to-point) without regard to any internet headers or protocols, I could use this chip instead of the RS422 parts.
I realize it will preamble with a MAC and add a checksum, but as long as it doesn’t force any restrictions on the payload between the MAC and the FCS I can use it.
I’m assuming I’d use MACRAW and socket buffer 0.
Is this possible?
