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/subsys/canbus/isotp
:board: twr_ke18f
:goals: build flash
Requirements
************
* Two boards with CAN bus support, connected together
