   Types for the C-level protocols





.. py:data:: ReadableBuffer
   

   Classes that implement the readable buffer protocol

   - `bytes`
   - `bytearray`
   - `memoryview`
   - `array.array`
   - `ulab.numpy.ndarray`
   - `rgbmatrix.RGBMatrix`


.. py:data:: WriteableBuffer
   

   Classes that implement the writeable buffer protocol

   - `bytearray`
   - `memoryview`
   - `array.array`
   - `ulab.numpy.ndarray`
   - `rgbmatrix.RGBMatrix`


.. py:data:: AudioSample
   

   Classes that implement the audiosample protocol

   - `audiocore.WaveFile`
   - `audiocore.RawSample`
   - `audiomixer.Mixer`
   - `audiomp3.MP3Decoder`
   - `synthio.MidiTrack`

   You can play these back with `audioio.AudioOut`, `audiobusio.I2SOut` or `audiopwmio.PWMAudioOut`.


.. py:data:: FrameBuffer
   

   Classes that implement the framebuffer protocol

   - `rgbmatrix.RGBMatrix`


.. py:data:: Alarm
   

   Classes that implement alarms for sleeping and asynchronous notification.

   - `alarm.pin.PinAlarm`
   - `alarm.time.TimeAlarm`

   You can use these alarms to wake up from light or deep sleep.
