The periodic message scheduler service can be used to send CAN messages at fixed intervals (update rate).

The schedule may contain one or many messages consisting of a single or an array of buffers. The buffer contains the MXF_CANBUS_DATAREC record to transmit. The schedule is characterized by its update rate and start time relative to other messages (phase).

If the list consists of one record, then a single CAN message is sent at the message update rate. If a message includes many records, then the message frame containing all MXF_CANBUS_DATAREC is sent at the message update rate.

The complete logic of the scheduler to send messages is explained in the section Scheduled Transmit Service.

The next sections demonstrate how to send and update periodic messages.
