Henrik Brix Andersen 3f97d11afd drivers: can: convert enum can_mode to a bit field Convert the can_mode enum to a bit field to prepare for future extensions (CAN-FD mode, transmitter delay compensation, one-shot mode, 3-samples mode, ...). Rename the existing modes: - CAN_NORMAL_MODE -> CAN_MODE_NORMAL - CAN_SILENT_MODE -> CAN_MODE_LISTENONLY - CAN_LOOPBACK_MODE -> CAN_MODE_LOOPBACK These mode names align with the Linux naming for CAN control modes. The old CAN_SILENT_LOOPBACK_MODE can be set with the bitmask (CAN_MODE_LISTENONLY \| CAN_MODE_LOOPBACK). Signed-off-by: Henrik Brix Andersen <hebad@vestas.com>		2022-05-11 10:47:54 +02:00

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:
