6. 채널 정보 출력 2 ☆보완필요☆

이전 게시글에서 driverConfig.channel 배열에 접근하여 각 채널의 정보를 읽어보았다

 

각 채널마다 설정된 비트레이트, 샘플 레이트 등 추가적인 정보를 확인하는 방법을 알아보자

 

이전 게시글에서 보았던 xl_channel_config 클래스의 구조 중에서

 

public class xl_channel_config
{
	... 생략
            
	public xl_bus_params busParams;
            
	... 생략
}

 

 

 

 

xl_bus_params 클래스를 멤버로 갖고 있음을 알 수 있는데, 위 클래스의 구조를 살펴보면 아래와 같다

---

 

public class xl_bus_params
{
	public XLDefine.XL_BusTypes busType;
	public xl_can_bus_params dataCan;
	public xl_canFd_bus_params dataCanFd;
	public xl_most_bus_params dataMost;
	public xl_flexray_bus_params dataFr;
	public xl_ethernet_bus_params dataEth;
	public xl_a429_bus_params dataA429;

	public xl_bus_params();
}

 

 

이들 중에서 xl_can_bus_params 클래스와 xl_canFd_bus_params 클래스를 우선 알아보자

 

---

xl_can_bus_params 

 

public class xl_can_bus_params
{
	public uint bitrate;
	public byte sjw;
	public byte tseg1;
	public byte tseg2;
	public byte sam;
	public byte outputMode;
	public byte[] reserved;
	public byte canOpMode;

	public xl_can_bus_params();
}

 

 

 

 

xl_canFd_bus_params 

 

public class xl_canFd_bus_params
{
	public uint arbitrationBitRate;
	public byte sjwAbr;
	public byte tseg1Abr;
	public byte tseg2Abr;
	public byte samAbr;
	public byte outputMode;
	public byte sjwDbr;
	public byte tseg1Dbr;
	public byte tseg2Dbr;
	public uint dataBitRate;
	public byte canOpMode;

	public xl_canFd_bus_params();
}

 

조금의 차이는 있지만 공통적으로 tseg 변수와 outputMode, bitRate 변수들이 존재함을 알 수 있다.

 

추가적인 호출 메소드들이 있는지 알아봐야 하겠지만 우선 5번 게시글의 예제처럼 각 멤버 변수에

접근하여 출력 및 수정할 수 있다.

 

아래의 코드 예제를 확인해보자

계속하려면 아무 키나 누르십시오 . . .

 

tseg 값들과 bitrate가 출력된 것을 확인할 수 있습니다.

 

 

 

tseg의 값을 직접 접근하여 바꿔보는 것을 시도해보겠습니다.

 

멤버 변수에 직접 접근하여 tseg1의 값을 변경하려면 아래와같이 tseg1 = 100; 으로 바꿔주는 코드를 추가하고

 

// 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);

driverConfig.channel[i].busParams.dataCan.tseg1 = 100;

Console.WriteLine("                    - tseg1           : " + 
    driverConfig.channel[i].busParams.dataCan.tseg1);
Console.WriteLine("                    - tseg2           : " + 
    driverConfig.channel[i].busParams.dataCan.tseg2);
Console.WriteLine("                    - bitrate         : " + 
    driverConfig.channel[i].busParams.dataCan.bitrate);
}
