//| """Analog buffered hardware support
|
|
//|
|
|
//| The `adcbuffer` module contains classes to provide access to analog-to-digital
|
|
//| conversion and digital-to-analog (DAC) for multiple value transfer.
|
|
//|
|
|
//| All classes change hardware state and should be deinitialized when they
|
|
//| are no longer needed if the program continues after use. To do so, either
|
|
//| call :py:meth:`!deinit` or use a context manager. See
|
|
//| :ref:`lifetime-and-contextmanagers` for more info.
|
|
//|
|
|
//| For example::
|
|
//|
|
|
//| import adcbuffer
|
|
//| import array
|
|
//| from board import *
|
|
//|
|
|
//| length = 5000000
|
|
//| mybuffer = array.array("H", [0] * length)
|
|
//| adcbuf_obj = adcbuffer.BufferedInput(GP26, mybuffer, length)
|
|
//| adcbuffer.readmultiple()
|
|
//| print(*mybuffer)
|
|
//| adcbuf_obj.deinit()
|
|
//|
|
|
//| This example will initialize the the device, read and fill
|
|
//| :py:data:`~adcbuffer.BufferedInPut` to mybuffer and then
|
|
//| :py:meth:`~adcbuffer.BufferedInPut.deinit` the hardware. The last step is optional
|
|
//| because CircuitPython will do it automatically after the program finishes.
|
|
