Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

ISO-TP library
##############

Overview
********
This sample demonstrates how to use the ISO-TP library.
Messages are exchanged between two boards. A long message, that is sent with
a block-size (BS) of eight frames, and a short one that has an minimal
separation-time (STmin) of five milliseconds.
The send function call for the short message is non-blocking, and the send
function call for the long message is blocking.

Building and Running
********************
Use these instructions with integrated CAN controller like in the NXP TWR-KE18F
or Nucleo-F746ZG board.

For the NXP TWR-KE18F board:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/CAN
   :board: twr_ke18f
   :goals: build flash

Requirements
************

* Two boards with CAN bus support, connected together

Sample output
