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:

# From the root of the zephyr repository
west build -b twr_ke18f samples/drivers/can
west flash

Requirements

• Two boards with CAN bus support, connected together

Sample output
