Unable to start channel CAN communication

Hi, i'm using this demo to communicate with my CAN adapter

canChannelObj = canChannel('PEAK-System', 'PCAN_USBBUS1');
start(canChannelObj);

But i constantly get this error: Unable to start channel.

In PCan View the communications start and all the drivers are installed.

Hi,

As per my understanding, you are using MATLAB to interface with a "PEAK-System PCAN-USB" using the Vehicle Network Toolbox. Please refer to the following as a possible workaround to the error :

• The "canChannel" function requires Vehicle Network Toolbox. You can check if the toolbox is installed correctly using the following command.

ver('vehicle_network_toolbox')

• Use MATLAB's "unload" library function to reset the interface. Refer to the following command for the same.

unloadlibrary('PCANBasic')

You can also refer to the following MathWorks documentation for better understanding the function.

https://in.mathworks.com/help/matlab/ref/unloadlibrary.html

• Also, check if you have "PCAN-Basic API" installed along with "PCAN-View".
• You adapter might be listed under a different name, run "canChannelList" in MATLAB to check the available channels.

Hope this helps!
