CANoe/CANalyzer A collection of basic tutorials

Tutorial demo version CANoe 12.0.75

Catalog

1. New project

2. Channel number and baud rate configuration

3.CANoe Mapping configuration of software channel and hardware channel

4. Add bus communication database dbc file

1. New project

In the main menu bar at the top of the software , choice File-New, Then according to the bus type , Communication rate , And the number of channels. Select the appropriate template to create the project . Choose here CAN Bus 500K Baud rate 2 Channel template creation , Then click... In the upper right corner Create Configuration.

2. Channel number and baud rate configuration

  After creating the project , You can click... In the main menu bar above Hardware--Channel Usage Further configure the number of channels of the bus , You can select the required number of channels from the drop-down box after the corresponding bus name .

Click... In the main menu bar above Hardware--Network Hardware Each channel can be configured CAN The rate of communication , And actually connected ECU The communication rate shall be consistent .

3.CANoe Mapping configuration of software channel and hardware channel

In the example, a two-way CAN The Internet CAN1,CAN2, CANoe Through the hardware here is VN1630A Connected to the real vehicle CAN Bus ,VN1630A There are multiple channels as shown in the figure below ：VN1630A Usually with usb Interface to the computer , It has two interfaces representing four channels ,CH1/CH3, CH2/CH4, Used in actual test VN1630A Which port and which channel are connected to the real vehicle CAN Bus Keep the settings consistent in the software .

CANoe Software settings VN1630A Mapping settings of hardware channel and software channel

Click on Hardware-Network Hardware-Driver Configure the hardware channel used by the network in the software  

Back click driver The hardware configuration dialog box pops up , Click on your hardware device , Here is VN1630A Sinister "+" Eject all its channels , Suppose I use VN1630A Of CH1 passageway 1 Connected to real vehicle , There will be VN1630A Of CH1 passageway 1 Right click to set and CANoe Of CAN1 Network matching .

At this step, the project creation and channel configuration have been completed , This is the time CANoe Has been able to receive ECU The message sent .

4. Add bus communication database dbc file

if necessary CANoe Better parsing ECU Interactive message , You can add .dbc file ,dbc The document contains ECU Byte length of message , Physical meaning , Message name , Signal name, etc .

 

Operate according to the above figure , stay CANoe Of simulation setup On the right side of the window CAN Under the Internet database Right click the node to select "Add", Then add .dbc File can .
