CAPL编程使用Timer作为延迟

问题描述

我一直在编写CAPL脚本，该脚本会在一定的延迟后在每个通道（2个不发送）上发送消息。我想使用 SetTimer（）和 mstimer :: isRunning 函数生成以下延迟。
我可以使用setTimer函数，但是我不知道如何使用 mstimer :: isRunning 。
代码如下所示：

I have been writing a CAPL script that would send message on each channel (2 no's) after a certain delay. The following delay i want to generate using SetTimer() and mstimer::isRunning function.I can use setTimer function but I dont know how to use mstimer::isRunning.The code is shown below:

    Variables{
          message * temp = {DLC=8};
          mstimer timer1;
    }
    on timer timer1{
        //Do nothing
    }
    onstart{

    for(noofChannel=1;noofChannel<=2;noofChannel++){
        settimer(timer1,100);
        temp.CAN = noofChannel;
        temp.ID = 0xAA;
        While (mstimer::isrunning)==0 // I need to write this right.
        { //wait for timer to expire}
        Output(temp);

    }

推荐答案

mstimer :: isrunning 使用 isTimerActive（）方法。
isTimerActive（）如果计时器正在运行，则返回1，如果计时器已过期，则返回0。
因此您的代码应如下所示：

Instead of mstimer::isrunning use isTimerActive() method.isTimerActive() returns 1 if timers is running and 0 if it is expired.So your code will look like:

on start{

    for(noofChannel=1;noofChannel<=2;noofChannel++){
        settimer(timer1,100);
        temp.CAN = noofChannel;
        temp.ID = 0xAA;
        While (isTimerActive(timer1) == 1)
        { //wait for timer to expire}
        }
        Output(temp);

      }
    }

但我不建议这样做。您可以通过 onTimer

But I would not recommend doing this. Instead of looping in on start, you can ouput 2nd message through onTimer

on start{
            temp.CAN = 1;
            temp.ID = 0xAA;
            Output(temp);
            settimer(timer1,100);
        }

on timer timer1{
    temp.CAN = 2;
    Output(temp);
}

如果要保持通用性，即不限于2个频道，可以取一个变量并在计时器中将其递增。

If you want to keep it generic i.e. not restricting to 2 channels, you can take a variable and increment it in timer.
