Development tool for CAN bus simulation
Most of automotive projects need to have an access to the Controller Area Network (CAN) bus. There are plenty of commercial frameworks that provides CAN stacks and hardware/software tools necessary to develop proper CAN networks. They are very comprehensive and thus expensive. CANdevStudio aims to be cost-effective replacement for CAN simulation software. It can work with variety of CAN hardware interfaces (e.g. Microchip, Vector, PEAK-Systems) or even without it (vcan and cannelloni) . CANdevStudio enables to simulate CAN signals such as ignition status, doors status or reverse gear by every automotive developer. Thanks to modularity it is easy to implement new, custom features.

Access to CAN bus is based on Qt framework. Current list of supported CAN interfaces can be found here.
Current list of devices compatible with SocketCAN (Linux only) can be found here.
CANdevStudio project uses Travis CI (Linux) and AppVeyor (Windows) continuous integration tools. You can always check .travis.yml and .appveyor.yml files for building details.

Binary packages are automatically uploaded by CI tools (i.e. Travis and Appveyor) to Bintray artifactory for every commit on master branch.
Use Bintray badges above to dowload stable or develop version (each commit on master creates corresponding binary packege in Bintray)
CANdevStudio-X.Y.ZZZZZZZ-SYS[-standalone]
X - major version number of previous stable version
Y - minor version of previous stable version
Z - SHA commit ID
SYS - either win32, Linux or Darwin
standalone - bundle version that contains Qt libraries and all relevant plugins.
All packages are being built on Ubuntu 18.04 LTS. You may experience problems with missing or incompatible libraries when trying to run the package on other distros.
To run standalone version use CANdevStudio.sh script.
Packages built with MinGW 5.3.
Standalone version contains Qt and MinGW runtime libs.
Package is a DMG installer.
General instructions to start your first simulation:
1. Build the latest master or release.
2. Run the application and start a new project
3. Drag and drop CanDevice and CanRawView components and connect them accordingly.
4. Double click on CanDevice node to open configuration window.
1. set one of supported backends (e.g. socketcan) link.
NOTE: List of supported backends depends on Qt version.
2. set name of your can interface (e.g. can0)
5. Start the simulation
6. Double click on CanRawView component to see CAN traffic
Steps required to use specific CAN hardware or virtual interfaces require some additional steps listed in following sections.
The list below shows hardware that has been successfuly used with CANdevStudio.
ip link
sudo ip link set can0 type can bitrate 1000000
sudo ip link set can0 up
sudo ip link set can0 type can termination 1
sudo ip link set can0 type can termination 120
CanDevice backend: socketcan
Configuration:
1. Create SocketCAN device from serial interface
sudo slcand -o -c -s8 -S1000000 /dev/ttyUSB0 can02. Bring the device up
sudo ip link set can0 up
CanDevice backend: socketcan
CanDevice settings example:
backend: peakcan interface: usb0 configuration: BitRateKey = 250000
CanDevice settings example for PEAK-PCAN:
backend: passthrucan configuration: BitRateKey = 250000 interface: PCANPT32CanDevice settings example for SIE_CANUSB:
backend: passthrucan configuration: BitRateKey = 250000 interface: CANUSB
CANdevStudio can be used without actual CAN hardware thanks to Linux's built-in emulation.
Configuration:
sudo modprobe vcan sudo ip link add dev can0 type vcan sudo ip link set can0 upCanDevice backend: socketcan
A SocketCAN over Ethernet tunnel. Available for Linux only.
Let's consider setup as before:
Target configuration:
sudo modprobe vcan sudo ip link add dev can0 type vcan sudo ip link set can0 up cannelloni -I can0 -R 192.168.0.1 -r 30000 -l 20000PC configuration:
Target configuration:
sudo modprobe vcan sudo ip link add dev can0 type vcan sudo ip link set can0 up cannelloni -I can0 -R 192.168.0.1 -r 30000 -l 20000PC configuration: 1. Execute following lines in a shell
sudo modprobe vcan sudo ip link add dev can0 type vcan sudo ip link set can0 up cannelloni -I can0 -R 192.168.0.2 -r 20000 -l 300002. Create new project in CANdevStudio and add CanDevice node 3. Configure CanDevice: 1. backend: socketcan 2. interface: can0 4. Start simulation
CANdevStudio provides support for CAN signals handling. DBC database description format is supported. Reverse engineered DBC files can be found in opendbc project.
Support for others CAN database formats can be added via extension of CANdb.
CanDevice component can be confiugred using "configuration" property: * Format - "key1=value1;key2=value2;keyX=valueX" * Keys names are case sensitive, values are case insensitive * Configuration keys are taken from ConfigurationKey enum. * RawFilterKey and ErrorFilterKey are currently not supported * DataBitRateKey is available since Qt 5.9 * Whitespaces are ignored
E.g.
BitRateKey=100000;ReceiveOwnKey=false;LoopbackKey=true
CanRawFilter component enables to filter (i.e. accept or drop) incoming and outgoing frames: * Qt regular expressions are used to match filter rules. * Rules are matched from top to bottom * Default policy is applied to frames unmatched by any filter
Examples: * match 0x222 and 0x333 frames only [id field]
222|333* match 0x200 - 0x300 frames only [id field]
^[23]..$* match empty payload (DLC 0) [payload field]
^$* match 2 byte payload (DLC 2) [payload field]
