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.
