Martin Jäger 9cec058e8e boards: posix: native_posix: enable can_loopback0 by default The .yaml file states that CAN is supported, but the basic sample application samples/drivers/can/counter cannot be compiled without additional configuration. The loopback driver does not require any additional steps like the linux SocketCAN driver, so it is safe to enable it by default and get rid of the many overlay files in the tests. ISO-TP tests and the counter sample are excluded via .yaml from twister tests because of timing issues. Signed-off-by: Martin Jäger <martin@libre.solar>		2022-10-03 10:17:12 +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:
