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.

## 0.5.3

### Added

* None.

### Changed

* **Receive path validation**: Tightened frame-length validation across all adapters so that incoming frames cannot exceed the underlying buffer or protocol limits. Invalid frames are now handled defensively instead of propagating unexpected sizes to the application.

### Fixed

* **`ArrayPoolBufferAllocator` `Memory` length**: Fixed an issue where the created `Memory` slice could expose a `Length` greater than the size of the rented buffer.
* **SocketCAN Classic receive payload size**: Corrected the maximum application data length for Classic CAN frames in the SocketCAN receive path from 64 bytes to 8 bytes.
* **Adapter receive robustness**: Added length constraints to the `Receive` implementations of other adapters to prevent exceptions when the underlying interface returns malformed or oversized data.

### Performance

* None.

### Breaking changes

* None. (Only invalid / over-sized frames are now rejected more defensively instead of causing exceptions.)
