- *
- * Specific configuration options for this example include:

- * CONFIG_NSH_BUILTIN_APPS - Build the CAN test as an NSH built-in function.
- * Default: Built as a standalone problem
- * CONFIG_CAN_LOOPBACK
- * CONFIG_EXAMPLES_CAN_DEVPATH - The path to the CAN device. Default: /dev/can0
- * CONFIG_EXAMPLES_CAN_NMSGS - If CONFIG_NSH_BUILTIN_APPS
- * is defined, then the number of loops is provided on the command line
- * and this value is ignored. Otherwise, this number of CAN message is
- * collected and the program terminates. Default: If built as an NSH

- * indefinitely.
- * CONFIG_EXAMPLES_CAN_READONLY - Only receive messages
