Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +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:
