| event_source_t CANDriver::rxfull_event |
One or more frames become available.
- Note
- After broadcasting this event it will not be broadcasted again until the received frames queue has been completely emptied. It is not broadcasted for each received frame. It is responsibility of the application to empty the queue by repeatedly invoking
chReceive()when listening to this event. This behavior minimizes the interrupt served by the system because CAN traffic. - The flags associated to the listeners will indicate which receive mailboxes become non-empty.
