main()

    }

Notes and Warnings

flush(CAN1); or flush(CAN2); flushes only buffer and does not resets any of the can filters or masks.

flush(RS232) or flush(RS485) flushes buffer even if transmission is in progress which results in data loss. For this reason it is recommended to flush before transmitting instead of after.
