Nope, we would need the opposite of this device, which would create 2 hosts that talk to each other.
Nope, cause the null modem connection is to connect two hosts together and not two devices.
Jinx you owe me a mod-chip programmer!
Ah that’s a shame. Oh well
Only sorta, it might be possible to get a low level chip like this to provide such a host connection. I think the SAMD can do a host?
You’d need a device with 2 of those and an mcu.
Or 1 of those and an mcu with built in host.
Link cable prototype works! KUDOS to @MLXXXp
Using two MAX485 so that it runs in full duplex, next design will be to use a single chip that can do full duplex, at 3.3v so that it is more closer to the USB-C specification.
Using the high speed lines of the USB-C cable is allowed, but technically you are supposed to do a handshake first.
However my configuration will have it set to USB 2.0 so these extra conductors should be disconnected or tri-stated on the host device.
Even so, all of the pins on USB-C are supposed to remain 5v tolerant anyways.
