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 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:
# From the root of the zephyr repository west build -b twr_ke18f samples/subsys/canbus/isotp west flash
Two boards with CAN bus support, connected together
