|
|
|
|
Use ISO-TP library to exchange messages between two boards.
|
|
|
|
Overview
|
|
********
|
|
This sample demonstrates how to use the :ref:`ISO-TP library <can_isotp>`.
|
|
|
|
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 a 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/subsys/canbus/isotp
|
|
:board: twr_ke18f
|
|
:goals: build flash

|
Requirements
|
|
************
|
|
|
|
* Two boards with CAN bus support, connected together
|
|
|
|
