C#周立功CANET-200T（新）

来源：互联网发布：js 获取div的name 编辑：程序博客网时间：2024/06/09 20:26

之前写过一个关于CANET的文章，现在有所改进

CANET-200T有两个CAN的端口，用程序分别给这两个口发送和接受数据；启动这两个端口，要把两个端口当作两个设备来启动。

#启动CANET-200T的第一个端口

if (i == 1)
{

Int32 ll = 4001;//第一个端口号
i = VCI_SetReference(17, 0, 0, 0, CANip);

if (i == 1)//开启
{
//MessageBox.Show("start ok");
}
else
{
//MessageBox.Show("start error");

rc = new RestartCAN();
}
}
else
{
//MessageBox.Show("ERROR");

}

#启动第二个端口

public RestartCAN2 rc2;
public int isRes = 0;

public CANstart2()
{
int i = VCI_OpenDevice(17, 1, 0);;//第二个参数为设备索引号第二个设备设置为1
if (i == 1)
{

Int32 ll = 4002;//第二个端口号
i = VCI_SetReference(17, 1, 0, 0, CANip);

if (i == 1)//开启
{
//MessageBox.Show("start ok");
}

{
//MessageBox.Show("start error");
isRes = 1;
rc2 = new RestartCAN2();
}
}
else
{
//MessageBox.Show("ERROR");
}
}
}
}

#上述可以将CANET-200T的俩个端口都打开
