In-Vehicle SDK Package

This package provides the In-Vehicle SDK, offering a range of functionalities to support communication and operations with in-vehicle systems.

Features

The In-Vehicle SDK package includes the following interfaces and implementations:

1. Communication

   1. CommunicatorBase: Provides the capability to send and receive byte data over various protocols. The following implementations are available:

      • TcpCommunicator
      • UdpCommunicator
      • MulticastCommunicator
      • IsoTpCommunicator
      • DoipCommunicator

   2. RawSocketCommunicatorBase: Offers send, receive, and srp (send and receive answer) operations for py_pcapplusplus.Packet types. The following implementations are available:

      • Layer2RawSocket
      • Layer3RawSocket
      • WiFiRawSocket

   3. CanCommunicatorBase: Exposes the python-can functionality, offering operations like send, receive, sniff, and more. The following implementation is available:

      • CanCommunicatorSocketCan - A specific implementation for the socketcan driver

2. DoipUtils: A utility library for performing Diagnostic over IP (DoIP) operations, such as vehicle identity requests, routing activation, and more.

3. UdsUtilsBase: Used for performing Unified Diagnostic Services (UDS) operations, such as ECU reset, read DIDs, session change, and more. The following implementation is available:

   • UdsUtils - Can be initialized to work over DoIP/ISO-TP

4. IDeviceShell: Allows for the execution of shell commands. The following implementations are available:

   • AdbDeviceShell
   • SerialDeviceShell
   • SshDeviceShell

5. SomeipUtils: A utility library for SOME/IP operations, allowing the receive and parse services, and in these services invoke methods and subscribe to eventgroups

6. Plugins:

   • SessionChangeCrashDetector: a plugin that detects ECU crash based on UDS session change
   • UnrespondedTesterPresentCrashDetector: a plugin that detects ECU crash based on UDS TP that is not being responded
   • UdsEcuRecoverPlugin: a plugin responsible of recovering the ECU back to predefined UDS state - session and elevation
   • RelayResetPlugin: a plugin that resets a device via relay
   • UdsBasedEcuResetPlugin: a plugin that resets a device via UDS ECU Reset

7. ConfigurationManager: An API allowing to perform configuration of the IOT Device.

   • configure_actions(action/s) - can perform the following configuration actions on the device:
     1. IpAddAction - add an IP to an Ethernet interface, and optionally configure a route for this IP.
     2. IpRemoveAction - remove an existing IP from an Ethernet interface.
     3. CanConfigurationAction - configure CAN interface parameters. e.g. bitrate, sample-point, cc-len8-dlc flag and state.
     4. EthInterfaceConfigurationAction - configure the Ethernet interface: mtu, state and flags.
     5. WifiConnectAction - connect to a WiFi access point
     6. CreateVlanAction - creating a VLAN interface
   • get_device_configuration() - retrieves the current device configurations:
     1. Ethernet interface configuration: state, IPs, flags and MTU.
     2. CAN interface configurations: state, bitrate, sample-point and cc-len8-dlc flag.
     3. The available WiFi access points.

Installation

You can install the In-Vehicle SDK package using pip:
pip install cyclarity-in-vehicle-sdk

Usage

Example for importing and using CanCommunicatorSocketCan for sending a Message

from cyclarity_in_vehicle_sdk.communication.can.base.can_communicator_base import CanMessage
from cyclarity_in_vehicle_sdk.communication.can.impl.can_communicator_socketcan import CanCommunicatorSocketCan

canmsg = CanMessage(
            arbitration_id=0x123,
            is_extended_id = False,
            is_rx=False,
            data=b"\x00" * 8,
            is_fd=False,
            bitrate_switch=False,
        )

socket = CanCommunicatorSocketCan(channel="vcan0", support_fd=True)
with socket:
    socket.send(can_msg=canmsg)
