| Socket CAN |
| ########## |
| |
| Overview |
| ******** |
| |
| 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`. |
| |
| Requirements |
| ************ |
| |
| You need a CANBUS enabled board like :ref:`nucleo_l432kc_board` or |
| :ref:`stm32f072b_disco_board`. |
| |
| Building and Running |
| ******************** |
| |
| Build the socket CAN sample application like this: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/net/sockets/can |
| :board: <board to use> |
| :conf: <config file to use> |
| :goals: build |
| :compact: |
| |
| Example building for the nucleo_l432kc: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/net/sockets/can |
| :host-os: unix |
| :board: nucleo_l432kc |
| :goals: run |
| :compact: |
