5. 채널 정보 출력

앞서 보여드린 4번 게시글의 예제에서 채널의 개수를 확인하는 코드를 보았습니다.

 

이번 게시글에서는 7개 채널들 각각의 정보를 출력하는 방법을 알아보겠습니다.

 

우선 driverConfig 클래스의 형태를 알아야 합니다. 구성요소는 아래와 같습니다.

 

---

(참고) class XLClass 내부에 선언되었습니다

 

public class xl_driver_config 구조

public class xl_driver_config
{
	public uint dllVersion;
	public uint channelCount;
	public uint[] reserved;
	public xl_channel_config[] channel;

	public xl_driver_config();
}

 

 

 

위 클래스에서 xl_channel_config 구조를 살펴보면 다음과 같습니다

 

public class xl_channel_config
        {
            public string name;
            public string transceiverName;
            public uint articleNumber;
            public uint serialNumber;
            public uint[] raw_data;
            public XLDefine.XL_InterfaceVersion interfaceVersion;
            public uint driverVersion;
            public xl_bus_params busParams;
            public XLDefine.XL_BusTypes connectedBusType;
            public uint[] reserved;
            public byte isOnBus;
            public XLDefine.XL_ChannelCapabilities channelCapabilities;
            public ulong channelMask;
            public byte channelIndex;
            public XLDefine.XL_Transceiver_Status transceiverState;
            public XLDefine.XL_Transceiver_Types transceiverType;
            public byte hwChannel;
            public byte hwIndex;
            public XLDefine.XL_HardwareType hwType;
            public XLDefine.XL_BusCapabilities channelBusCapabilities;

            public xl_channel_config();
        }

 

배열로 선언된 위 구조는 해당 채널의 정보를 포함하고 있습니다.

 

 

 

 

다시 예제로 돌아와서 각 채널들의 정보를 출력해보겠습니다.

 

xl_channel_coxl_driver_config 클래스의 xl_channel_config 클래스로 선언된

channel 변수의 멤버변수들을 접근하면 됩니다.

예제 코드

 

using System;
using System.Threading;
using Microsoft.Win32.SafeHandles;
using vxlapi_NET;

namespace XLpractice
{
    class Class1
    {
        // Driver access through XLDriver (wrapper)
        private static XLDriver CANDemo = new XLDriver();

        // Driver configuration
        private static XLClass.xl_driver_config driverConfig = new XLClass.xl_driver_config();


        [STAThread]
        static int Main(string[] args)
        {
            XLDefine.XL_Status status;

            Console.WriteLine("-------------------------------------------------------------------");
            Console.WriteLine("                     xlCANdemo.NET C# V11.0                        ");
            Console.WriteLine("Copyright (c) 2019 by Vector Informatik GmbH.  All rights reserved.");
            Console.WriteLine("-------------------------------------------------------------------\n");


            // print .NET wrapper version
            Console.WriteLine("vxlapi_NET        : " + typeof(XLDriver).Assembly.GetName().Version);

            // Open XL Driver
            status = CANDemo.XL_OpenDriver();
            Console.WriteLine("Open Driver       : " + status);
            if (status != XLDefine.XL_Status.XL_SUCCESS) PrintFunctionError();

            // Get XL Driver configuration
            status = CANDemo.XL_GetDriverConfig(ref driverConfig);
            Console.WriteLine("Get Driver Config : " + status);
            if (status != XLDefine.XL_Status.XL_SUCCESS) PrintFunctionError();

            // Display channel count
            Console.WriteLine("Channels found    : " + driverConfig.channelCount);

            // Display all found channels
            for (int i = 0; i < driverConfig.channelCount; i++)
            {
                Console.WriteLine("\n[{0}] " + driverConfig.channel[i].name, i);
                Console.WriteLine("  - Channel Mask    : " + driverConfig.channel[i].channelMask);
                Console.WriteLine("  - Transceiver Name: " + driverConfig.channel[i].transceiverName);
                Console.WriteLine("  - Serial Number   : " + driverConfig.channel[i].serialNumber);
                Console.WriteLine("  - hwtype          : " + driverConfig.channel[i].hwType);
                Console.WriteLine("  - hwIndex         : " + driverConfig.channel[i].hwIndex);
                Console.WriteLine("  - hwChannel       : " + driverConfig.channel[i].hwChannel);
                Console.WriteLine("  - Channel Index   : " + driverConfig.channel[i].channelIndex);
            }

            return 0;
        }

        private static int PrintFunctionError()
        {
            Console.WriteLine("\nERROR: Function call failed!\nPress any key to continue...");
            Console.ReadKey();
            return -1;
        }
    }
}

 

앞서 말씀드린 클래스 구조의 channel 변수의 모든 배열을 반복문으로 접근하여

각각의 멤버변수에 접근하는것을 볼 수 있습니다.

위 출력결과에서 물리채널들의 Serial Number 들과 각 채널들의 Mask 값과 정보들을 볼 수 있습니다.
