Hsu.Automotive.Uds.Can

CAN integration package for the UDS ecosystem.

This package bridges Hsu.Can.Core into the UDS transport model by providing a concrete ICanBus implementation. It is intended for projects that already work with the Hsu.Can wrapper model and want to plug that CAN stack into ISO-TP-based UDS communication.

Package Information

• Package ID: Hsu.Automotive.Uds.Can
• Package scope: CAN bus integration adapter for the UDS stack
• Depends on: Hsu.Automotive.Uds.Abstractions, Hsu.Can.Core
• Recommended for: CAN-based diagnostic tools, legacy framework consumers, adapter layers built on Hsu.Can

What This Package Provides

The package provides CanBus, a concrete implementation of ICanBus that:

• wraps an Hsu.Can.IWrapper
• converts wrapper frames into UDS-compatible CanFrame values
• supports receive-side filtering through SetFiltersAsync
• raises ErrorOccurred on transmit failures
• can be consumed by ISO-TP transport channels in the rest of the stack

Supported Capabilities

• adapter from Hsu.Can wrapper APIs to the UDS ICanBus abstraction
• classic CAN and CAN FD frame forwarding
• receive queue management and filter application
• compatibility with broader target frameworks than the main integrated package

Typical Use Cases

• reusing an existing Hsu.Can integration inside a UDS client or simulator
• connecting vendor-specific CAN wrappers to ISO-TP UDS channels
• supporting older .NET targets while keeping a dedicated CAN integration package

Common Usage

using Hsu.Automotive.Uds;
using Hsu.Automotive.Uds.Transport;
using Hsu.Can;

IWrapper wrapper = CreateWrapper();
await using var canBus = new CanBus(wrapper);

await using var channel = new IsoTpTesterChannel(
    canBus,
    physicalId: 0x7E0,
    responseId: 0x7E8);

In a full client application, the resulting ISO-TP channel is typically passed to UdsClient from Hsu.Automotive.Uds.Client.

When to Choose This Package

Choose Hsu.Automotive.Uds.Can when:

• your CAN access layer is already based on Hsu.Can.Core
• you want a ready-made ICanBus adapter instead of writing one yourself
• you need a small package focused on CAN integration rather than the full integrated stack

If your project already has its own ICanBus implementation, you may not need this package.

Install

dotnet add package Hsu.Automotive.Uds.Can

Package Relationships

• Hsu.Automotive.Uds.Core and Hsu.Automotive.Uds.Client consume ICanBus for ISO-TP-based communication.
• Hsu.Automotive.Uds.Server can also use CAN-based ECU transports built on the same abstraction.
• Hsu.Automotive.Uds.Abstractions provides the shared ICanBus and transport contracts used here.
