on linFrame

Valid for: CANoe DE • CANoe4SW DE

​
Description

The event procedure on linFrame is called on the receipt of a valid LIN frame. The keyword this and the selectors (see LIN: linFrame selectors) can be used to access the data of the frame that has just been received. CAPL nodes are by default not transparent to LIN frames. This means that a CAPL node in the evaluation branch of the Measurement Setup will block the data flow to its right side. To propagate the received frame to a next node in a chain a call to output(this) can be used. However, please note that such a call from a CANoe’s Simulation Setup node may lead to a recursion. Note If for example a CAPL program contains the event procedures on linFrame 12 and on linFrame *, the procedure on linFrame 12 will be called up, when a frame with the identifier 12 is received. For all other frames the procedure on linFrame * will be called up.

Example

Display in Write Window the transmission time for a frame from the database 
on linFrame MotorControl
{
    writeLineEx(1, 1, "Entire frame transmission time: %d bit times", this.LIN_Fulltime);
}
Display in Write Window the header transmission time for a frame ID=0x33 
on linFrame 0x33
{
    writeLineEx(1, 1, "Frame header transmission time: %d bit times", this.LIN_HeaderTime);
}
Propagate all frames to a next chain node 
// Warning: This code causes recursion when called from Simulation Setup node
on linFrame *
{
    this.RTR=1;
    output(this);
}
