Controller Area Network¶
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.
