A library to manage multiple keypad instances (and compatible) as a single event queue.

  • Author(s): Neradoc

Implementation Notes

Software and Dependencies:

class multi_keypad.Event(keypad, event, offset=0)

Event class, adds the keypad ID to the keypad event.

Parameters:

  • keypad (int) – The ID number of the keypad that generated that event.

  • event (obj) – The original keypad event.

  • offset (int) – The offset added to the key_number (default 0).

class multi_keypad.EventMultiQueue(keypads)

A queue of Event objects.

clear() → None

Clear any queued key transition events. Also sets overflowed to False.

get() → Event

Return the next key transition event. Return None if no events are pending.

get_into(event: Event) → bool

Puts the next event into the passed object. This does not avoid allocating storage because we have to cache events from the underlying keypads anyway. Only there for compatibility.

overflowed() → bool

True if an event could not be added to the event queue because it was full. (read-only) Set to False by clear().

class multi_keypad.MultiKeypad(*keypads)

Multi Keypad. Read events from multiple keypads as a single queue.

Parameters:

keypads (obj) – Instances of keypad scanenrs or compatible objects.

next_event()

Deprecated method to get the next event
