| 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. |
| 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. |
