Vector CANape - How to Send Receive CAN Message in CANape

Background summary

background

Why is this an article of value 10W+ The article ？

Because I was looking for a third party to develop a product based on CANape Calibration system , The price offered by the third party is 15W, At that time, I thought a lot about this tool , Finally, it developed from nothing based on CANape Calibration system , Of course , This article will give you a lot of inspiration .

Write This Artical to Record my notes,Whenever I forget the detail in Operated CANape.

The goal is

stay CANape To realize CAN Sending and receiving of messages Target

Message reception

There are two ways to receive Device | New Device | New from database

1. Device New

adopt Device Configuration Create a Monitor Class CAN node , Then enter the drive device name （ Custom English ）, as for comment Depending on personal preference .

• Click on Next
• Uncheck the use database for signal definition
• Click on Next
• Point selection Ok

• As shown in the figure above , Check the response node
• Click the lightning sign to start to accept the message

2. Devie New from database

If you master the first method , Then the second method is to build directly from the database , The premise is that you already have the project DBC file , Click directly as shown in the figure below Ok, Then the operation is similar

The advantage is that you can parse the received CAN message

Message sending

about CAN There are two kinds of message sending ：

1. No, DBC file , Randomly send a custom CAN ID

give an example ： send out CAN ID by 0x100 Of CAN Message , Data field is 1,2,3,4,5 .Tools | Function and script Open the function editor , stay Script Now create the following script and compile

//API
Device.SendMessage(messageID,value0,value1,)

// For example, I created DMGCanMsgSend Of Device
DMGCanMsgSend.SendMessage(0x100,1,2,3,4,5)

After compiling, you can make a panel with keys , Every time you click a key CAN Message sending .

tip

Create panels and data 、 Links between scripts , That is to change the sending function through the input value of the panel ID、 Data field

warning Be careful

Create global variables , Through global variables, scripts and panels can open a bridge of communication , So as to solve the communication between the panel and script data

2. Yes DBC file , Realize periodic or random transmission CAN data .

The basic idea is to create CAN Message sending function , Call the function periodically in the measurement configuration window , So as to achieve CAN The message is sent periodically .

give an example ： Still in Function and Script Window Function Create a new global variable for sending data
