CanKit.Adapter.Kvaser

Kvaser CANlib adapter for CanKit. Provides a unified .NET API to Kvaser devices via CANlib.

Requirements

  • Install Kvaser CANlib drivers/runtime from Kvaser.
  • Ensure CANlib is installed and the runtime is available on the machine. 简体中文
  • 需要安装 Kvaser CANlib 驱动/运行库。
  • 请确认目标机器已安装并能加载 CANlib 运行库。

Install

# Core + Kvaser adapter
dotnet add package CanKit.Core
dotnet add package CanKit.Adapter.Kvaser

Endpoint Formats

  • kvaser://0 (open by channel number)
  • kvaser://?ch=1 (query parameter)

Quick Start

using CanKit.Core;
using CanKit.Core.Definitions;

// Open Kvaser channel 0 at 500 kbps (Classical CAN)
using var bus = CanBus.Open("kvaser://0", cfg => cfg.Baud(500_000));

// Send a frame
var tx = CanFrame.Classic(0x321, new byte[] { 0xAA, 0xBB });
bus.Transmit(tx);

// Receive
foreach (var rx in bus.Receive(1, 100))
{
    var f = rx.CanFrame;
    Console.WriteLine($"RX 0x{f.ID:X} dlc={f.Dlc}");
}

Bus Usage (Bus Load)

  • Before calling BusUsage(), you must request statistics and wait briefly; or simply use BusUsageAsync() which handles the request + wait.
var kbus = (CanKit.Adapter.Kvaser.KvaserBus)bus;

// Option 1: manual request + read
kbus.RequestBusUsage();
await Task.Delay(250);
var load1 = kbus.BusUsage();

// Option 2: async helper
var load2 = await kbus.BusUsageAsync();

Discover Endpoints

using CanKit.Core.Endpoints;

foreach (var ep in BusEndpointEntry.Enumerate("kvaser"))
{
    Console.WriteLine($"{ep.Title}: {ep.Endpoint}");
}

Notes

  • Bit timing and FD support depend on the device and CANlib capabilities.

## 0.5.0

### Added

* **CanKit.Abstractions**: New project with a corresponding NuGet package.
* **Receive payload allocator**: `CanBus` receive path now supports an `IBufferAllocator` for `CanFrame` payloads to optimize memory usage and reduce GC. Two default implementations are included: `ArrayPoolBufferAllocator` and `DefaultBufferAllocator`.
* **Queued transmission**: Introduced `QueuedCanBus` that adds a TX queue to any existing bus. Create via `ICanBus.WithQueuedTx(QueuedCanBusOptions)`.

### Changed

* **Timing source**: ZLG and SocketCAN adapters now use `Stopwatch` instead of `Environment.TickCount` for more stable timing.

### Performance

* **Lower allocations on receive** via the allocator-based payload path.
* **Fewer conversions in hot paths** thanks to a unified frame type (see breaking changes).

### Breaking changes

* **Unified frame type**: Removed `ICanFrame`, `CanClassicFrame`, and `CanFdFrame`. Introduced a single `CanFrame` for all CAN frame kinds. Create frames using `CanFrame.Classic(...)`, `CanFrame.Fd(...)`, or `CanFrame.Create(...)`.

 * **Primary motivation**: Eliminate the boxing/unboxing and back-and-forth conversions between `ICanFrame` and concrete frame types, which previously added per-frame CPU overhead and extra allocations in hot paths. Unifying to `CanFrame` removes those interface–concrete transitions and reduces GC pressure.
