DigitalOutput¶
Take an EventData stream and sets digital outputs according to an event-specific.
The protocols option specifies a map with for each target event a map of actions for selected digital output channels. Note that each channel can only be associated with a single action (even if it is listed more than once). There are 4 possible actions (high, low, toggle and pulse). Events that are not in the protocols map are ignored.
Here are some example configurations:
{'protocols': {'event_a': {'high': [0, 1]}, 'event_b': {'low': [0], 'toggle': [1]}, 'event_c': {'pulse': [2]}}}
