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
None
Example Flowgraph
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.
