CAPL 脚本接收一次消息
[英]CAPL scripting receive a message once
问题描述
I have a requirement that mandates that each signal inside a frame will be sent at ECU initialization with an initial value.
我有一个要求，要求帧内的每个信号都将在 ECU 初始化时以初始值发送。 so I need to capture this value using CAPL what I did is that I defined a variable as follows:所以我需要使用 CAPL 捕获这个值我所做的是我定义了一个变量，如下所示：
first_reception = 0 ;
and then inside the message event I get the initial value if this variable equals to zero, and save it to a system variable then set first_reception to 1:然后在消息事件中，如果此变量等于零，我将获得初始值，并将其保存到系统变量中，然后将 first_reception 设置为 1：
{
if (first_reception == 0 )
{
@sysvar::mymsg::signal_initialValue = this.signal;
first_reception = 1;
}
}
the issue here is that I have many frames so I wonder if there is another way to call the event once so that I don't have to define a variable for each frame这里的问题是我有很多帧，所以我想知道是否有另一种方法可以调用一次事件，这样我就不必为每个帧定义一个变量
