The socket CAN sample is a server/client application that sends and receives raw CAN frames using BSD socket API.
The application consists of these functions:
- Setup function which creates a CAN socket, binds it to a CAN network interface, and then installs a CAN filter to the socket so that the application can receive CAN frames.
- Receive function which starts to listen the CAN socket and prints information about the CAN frames.
- Send function which starts to send raw CAN frames to the bus.
The source code for this sample application can be found at: :zephyr_file:`samples/net/sockets/can`.
You need a CANBUS enabled board like nucleo_l432kc_board or stm32f072b_disco_board.
Build the socket CAN sample application like this:
Example building for the nucleo_l432kc:
