agent-can

Agent-first CAN control daemon for real devices.

V1:

• one daemon per bus
• daemon started with adapter + DBC + bitrate config
• mailbox semantics for reads: latest decodable message per arbitration id
• undecodable frames dropped from the agent-visible surface
• raw send plus DBC-backed message send

Quick Start

nix develop -c bash -c 'cd runtime && cargo build'

agent-can open \
  --bus vehicle \
  --adapter usb1 \
  --dbc ./vehicle.dbc \
  --bitrate 500000

agent-can --bus vehicle status
agent-can --bus vehicle mailboxes
agent-can --bus vehicle send-raw 0x123 DEADBEEF
agent-can --bus vehicle send-message VehicleControl enable=1 torque_request=12
agent-can --bus vehicle close

Architecture

CLI client  <->  local JSON lines IPC  <->  bus daemon
                                            - CAN transport
                                            - DBC decode/encode
                                            - latest-message mailboxes
                                            - counters and drop stats

Primary target is Windows + PEAK CAN. The copied Linux SocketCAN path is retained for local bring-up and testing.
