[capnproto] What is the best communication mechanism with collision detection/avoidance for my topology?

[T Obulesu]

Hello All, Here is my sensor topology.. [image: enter image description

Here, the atmega128 is the main controller and all other atmega8 are
connected to the main controller using rs485 cable.

What is the best communication protocol for this to detect and avoid
collision.?

I have 20 atmega8 connected in a row..(i.e all the tx pins of atmega8 are
connected together and finally connected to the Rx of the main controller)
and distance between the any atmega8 or atmega128 is 3 meters....

Hi,

You seem to have mailed the Cap'n Proto mailing list. Cap'n Proto is a
serialization format typically used at OSI layer 6, e.g. between a client
and server communicating over the internet, or as a file format.

Your question doesn't seem to be in any way related to Cap'n Proto. Your
question seems to be about OSI layer 1 protocols (hardware link layer),
which are far away from anything Cap'n Proto does.

Sorry, I don't think we can help you.
