Debug block for the message passing system.

The message debug block is used to capture and print or store messages as they are received. Any block that generates a message may connect that message port to one or more of the three message input ports of this debug block.

The message ports are:

  • print: prints the message directly to standard out.
  • store: stores the message in an internal vector. May be access using the get_message function.
  • print_pdu: specifically designed to handle formatted PDUs (see pdu.h).

Parameters[edit]

None

Example Flowgraph[edit]

In this example, a Message Strobe block sends the string "Demo" once per second. It is displayed on the user terminal by the Message Debug block.
