CAPL Scripting - CAN C communication (Stop transmitting one message from DBC)

I am working on a CAPL script that has to allow all messages to transmit on a CAN C channel and stop transmitting one particular message from the database file. Can anyone help with the method/function/code I can use?

Solution

  • Your question is vague, but I'm assuming you are going from one CAN channel to another. For instance, CAN C to CAN D (or CAN 3 to CAN 4), than you could do:

    on message CAN3.0x7FF  // This would be that one ID that stops at some point
{
  message CAN4.0x7FF msg;
  msg = this;

  // Assuming you are receiving on CAN 3, and looking to transmit on CAN 4
  if(this.dir == rx)
  {
      // Declare a global variable that sets to 1 when you want it to stop
    if(MSG_STOP == 0)
       output(msg);
  }
}

on message CAN3.*
{

  message CAN4.* msg;
  msg = this;
  if (this.dir == rx)
  {
    output (msg);
  } 
}
