Overview
|
|
********
|
|
|
|
This sample demonstrates how to use the Controller Area Network (CAN) API.
|
|
Messages with standard and extended identifiers are sent over the bus.
|
|
Messages are received using message-queues and work-queues.
|
|
Reception is indicated by blinking the LED (if present) and output to the console.
|
|

|
Building and Running
|
|
********************
|
|
|
|
In loopback mode, the board receives its own messages. This could be used for
|
|
standalone testing.
|
|
|
|
The sample can be built and executed on boards supporting CAN.
|
|
The LED output pin is defined in the board's device tree.
