Controller Area Network
|
|
#######################
|

|
|
Overview
|
|
********
|
|
|
|
This sample demonstrates how to use the Controller Area Network (CAN) API.
|
|
Messages with standard and extended identifiers are sent over the bus, triggered
|
|
by a button event.
|
|
Messages are received using message queues and ISRs.
|
|
Reception is indicated by blink LEDs 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 output ports and pins of the LEDs can be configured by Kconfig.
