This directory contains the GNU Radio Eventstream Out-of-Tree Synchronous Stream-Event Scheduler
These blocks are intended to help improve the translation of
streams of data items into scheduled-finite length events
occurring in the data streams in both directions.
* es.sink provides the translation from stream to events
* es.source provides the translation from events to streams
* triggers cause events to be scheduled in es.source
and es.sink block event queues.
Some examples of specific triggers included are,
- es_trigger_edge_f: cause an event when float stream rises
above a fixed threshold value
- es_trigger_sample_timer: cause an event to occur on
a periodic sample increment in the stream
* handlers consume events and do some ammount of signal
processing on them
Some example of specific handlers included are,
- es_handler_print: print the event to STDOUT
- es_handler_pdu: convert the event to a PDU and send
it out a message port
- es_handler_insert_vector: a source handler which
populates an event window from a PMT vector
- es_handler_file: a sink handler which writes event
contents out to a file
