## Overview

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](https://github.com/mguentner/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.

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 20000

```

PC 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 30000

```

2. Create new project in CANdevStudio and add CanDevice node

3. Configure CanDevice:

   1. backend: socketcan

   2. interface: can0

4. Start simulation



## Help

### Scripting

As of v1.1 CANdevStudio supports creation of [QML](https://doc.qt.io/qt-5/qmlapplications.html) based scripts. Scripts can be developed and loaded dynamically without a need to restart the main applications. Scripting adds a lot of different possibilities to CANdevStudio that includes:

* Creation of custom GUIs

* Raw frames and signals handling

* Time triggered actions

* Message triggered actions

* ... and many more, as all QML functionalities are supported.



Try it yourself by loading one of the [examples](https://github.com/GENIVI/CANdevStudio/tree/master/src/components/qmlexecutor/examples) into QMLExecutor component. You are welcome to share your scripts via Pull Requests!



### CAN Signals

CANdevStudio provides support for CAN signals handling. [DBC](http://socialledge.com/sjsu/index.php/DBC_Format) database description format is supported. Reverse engineered DBC files can be found in [opendbc](https://github.com/commaai/opendbc) project.



Support for others CAN database formats can be added via extension of [CANdb](https://www.github.com/GENIVI/CANdb).



#### Sending signals

1. Start new project and setup CanDevice as described in quick start section

2. **Add CanSignalData** component that serves as CAN signals database for other components. You may have multiple CanSignalData components per projecthttps://github.com/commaai/opendbc

3. Open CanSignalData properties and configure path to DBC file

4. List of messages and signals shall be now loaded and visible in CanSignalData window

5. You may configure cycle and initial value per each message

6. **Add CanSignalEncoder** component and connect it with CanDevice. CanSignalEncoder act as a translator between signals and CAN frames. It is also  responsible for sending cyclical messages.

7. CanSignalSender has been automatically configured to use previously added CAN database. CAN database can be manually selected in component properties (this applies to all components from "Signals" group)

8. **Add CanSignalSender** component and connect it with CanSignalEncoder

9. Add signals in CanSignalSender window

10. Start simulation

11. CanSignalEncoder will start sending cyclical messages

12. You can send previously configured signals from CanSignalSender:

    * if signal is a part of periodic message its value will be updated in a next cycle

    * if signal is not a part of periodic message it will be sent out immediately



#### Receiving signals

1. Start new project and setup CanDevice as described in quick start section

2. **Add CanSignalData** component that serves as CAN signals database for other components. You may have multiple CanSignalData components per project

3. Open CanSignalData properties and configure path to DBC file

4. List of messages and signals shall be now loaded and visible in CanSignalData window

5. **Add CanSignalDecoder** component and connect it with CanDevice. CanSignalDecoder act as a translator between signals and CAN frames.

6. CanSignalDecoder has been automatically configured to use previously added CAN database. CAN database can be manually selected in component properties (this applies to all components from "Signals" group)

7. **Add CanSignalViewer** component and connect it with CanSignalDecoder

8. Start simulation

9. Signals shall now appear in CanSignalViewer. Note that CanSignalDecoder is sending over only signals which values has changed.



### CanDevice configuration

CanDevice component can be configured 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](https://doc.qt.io/qt-5/qcanbusdevice.html#ConfigurationKey-enum). 

* RawFilterKey and ErrorFilterKey are currently not supported

* Whitespaces are ignored



E.g.

```

BitRateKey=100000;ReceiveOwnKey=false;LoopbackKey=true

```

### CanRawFilter

CanRawFilter component enables to filter (i.e. accept or drop) incoming and outgoing frames:

* [Qt](https://doc.qt.io/qt-5/qregularexpression.html) 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]

```

^.{4}$

```

### Adding new components

1. Configure build to include *templategen* tool

```

cd build

cmake .. -DWITH_TOOLS=ON

make

```

2. Generate component (use -g option if you don't need component to have GUI)

```

./tools/templategen/templategen -n MyNewComponent -o ../src/components -g

```

3. CMake script automatically detects new components. It has to be invoked manually.

```

cmake ..

```

4. Build project 

``` 

make

```

5. Your component is now integrated with CANdevStudio

6. You may want to modify *src/components/mynewcomponent/mynewcomponentplugin.h* to configure section name, color and spacing

7. Define component inputs and outputs in *src/components/mynewcomponent/mynewcomponentmodel.cpp*. Look for examples in other components.

8. Modify automatically generated unit tests *src/components/mynewcomponent/tests*
