CAPL SCRIPTING PDF

The execution of program blocks is controlled by events. CAPL programs are developed and compiled in a dedicated browser. This makes it possible to access all of the objects contained in the database messages, signals, environment variables as well as system variables. In three consecutive articles, CAPL fundamentals will be discussed as well as tips for all levels of user knowledge. It focuses on the basics of CAPL. It is primarily intended for those who are new to this language; however, it also offers a few insights for well-informed users into the motivation behind individual CAPL constructs.

If you want send the extended frame the IDE bit in the orbitration field should be recessive 1. HI, for can extended messages put x after identifier. Hi can any help how to extract data from text file and send it on message in capl.

If that text file consist message bytes which are supposed to send on bus like 00 00 00 00 Hi, You have mentioned here that we can create cyclic events with timers, but didn't make an example of that. If I reset the timer in my "on timer" by using the setTimer then how will the program go back to the beginning of my "on timer" to run the code there again?

This is not working for me, it always only run once. Also how can I put timer in a for loop? Can someone write me a script for this in CAPL, kindly help. I really need it, kinda priority now. IT will be a big help if anyone can do it. RQ 6 Default value of output frequency is 10 Hz RQ 7 If the input signal with the frequency is in error 0 , output is disabled RQ 8 If the input signal frequency is in range , output frequency is in default 2 Make the test specification for the RQ1-RQ8.

I have found this post helpful. I have a question tho. How can you send a cyclic message between two signals. How can I program this so that I can send the message with both signals alternating for a specific number of times?

Is it possible to convert a string in to bytes in CAPL , if yes please let me know how , example : my string is "10 01" How do I compare my received message to something to verify what I've received is correct or not? Hello, I want to change message ID using capl scripting In run time. I know this is not a proper scenario but right now i am working with this kind of requirement.

Please let me know if you have some idea on it. Thank you, Akash Shah. CAPL Basics. These program blocks are known as event procedures. The program code that you define in event procedures is executed when the event occurs. For example, you can send a message on the bus in response to a key press on key , track the occurrence of messages on the bus on message , or execute certain actions cyclically on timer.

A CAPL program consists of two parts:. Declare and define global variables. Declare and define user-defined functions and event procedures. CAPL programs have three distinct parts:. Global Variable Declarations. Event Procedures. User-Defined Functions. Data types available for variables include integers dword , long , word , int , byte , char , floating point numbers float and double ,.

CAN messages message and timers timer or msTimer. Except for the timers, all other variables can be initial-ized in their declarations. With the exception of timers, the compiler initializes all variables with default values unless otherwise defined: 0.

CAPL permits the declaration of arrays arrays, vectors, matrices , analogous to their declaration in the C programming language. The complete declaration includes the message identifier or - when work-ing with symbolic databases - the message name. For example, you might write the following to output messages on the bus that have identifier A hex or dec or the message EngineData defined in the database.

It is possible to access control information for the CAN message objects using the following component selectors:. You can react to the following events in CAPL using event procedures :. Initialization of measurement before meas-urement start. Receiving chip is not considered.

With on key procedures you can execute certain actions by key press. The code for a key press can either be input as a character, number or a predefined name for a function key. Note:Remember that environmental variables are only enabled in CANoe. Thisfacility can be used to create a cyclic event if you reset the timer at the end of the timer event procedure. Timers can also be used to respond to an event after a delay. The setTimer function takes two parameters, the name of the timer and the length of time to setthe timer.

The length of time parameter has different units depending on what kind of timer youare using. For a Timer, the units are seconds; for an msTimer, the units are milliseconds. Themaximum values are seconds and 65, milliseconds, respectively.

The cancelTimer function can be called on a timer before it has expired to prevent the timer event from triggering. Calling the cancelTimer function has no effect if the timer is not set or has already expired. Set timer to 20 ms. If they are defined, each is called once permeasurement. You use this procedure to read data from files, initializevariables, or write to the Write window.

Other actions, such as outputting a message onto thebus, are not available in the preStart event. Generally, actions that are invalid in the preStart event procedure can be moved to the start event procedure. After the preStart event procedure has completed executing, the start event procedure is executed if one exists. The start event procedure can be used to initialize environmental variables, set timers, and output messages onto the bus.

The measurement is also started at this time. You can use this procedure to print statistics in the Write window, output messages onto the bus, or write to a log file. After this event has finished executing, the measurement is stopped. The key word this is used to refer to the the data structure of an object within an event procedure for receiving a CAN object or environment variable. When information only needs to be transferred on an event basis, the event message is used.

When information requires transferring on a repetitive basis, the periodic message is used. When information requires transferring on a repetitive basis only when a certain set of conditions is true, the conditionally periodic message is used.

A number of run-time errors are monitored in CAPL:. If a run-time error is detected, the instrinsic function runError is called. This out-. The location of the particular CAPL source text which.

The measurement is termi-. The function runError can also be called directly by the user to generate asser-. Create a black box to simulate the rest of the network. Create a module simulator.

Simulate event messages, periodic messages, or conditionally repetitive messages. Simulate human events like button presses using the PC keyboard. Simulate timed node or network events. Create a functional gateway between to different CAN networks. CAPL Programming. Unknown June 3, at AM. Srikent June 14, at AM. Unknown April 22, at AM. Unknown December 10, at AM.
