This was done to allow greatly granularity when deciding what functionality is built into each board's build. For example, this way pulseio can be omitted to allow for something else such as touchio.

//| :mod:`busio` --- Hardware accelerated behavior
|
|
//| =================================================
|
|
//|
|
|
//| .. module:: busio
|
|
//| :synopsis: Hardware accelerated behavior
|
|
//| :platform: SAMD21
|
|
//|
|
|
//| The `busio` module contains classes to support a variety of serial
|
|
//| protocols.
|
|
//|
|
|
//| When the microcontroller does not support the behavior in a hardware
|
|
//| accelerated fashion it may internally use a bitbang routine. However, if
|
|
//| hardware support is available on a subset of pins but not those provided,
|
|
//| then a RuntimeError will be raised. Use the `bitbangio` module to explicitly
|
|
//| bitbang a serial protocol on any general purpose pins.
|

//| I2C
|
|
//| OneWire
|
|
//| SPI
|
|
//| UART
|
|
//|
|
|
//| All libraries change hardware state and should be deinitialized when they
|
|
//| are no longer needed. To do so, either call :py:meth:`!deinit` or use a
|
|
//| context manager.
|
|
//|
|
|
//| For example::
|
|
//|
|
|
//| import busio
|
|
//| from board import *
|
|
//|
|
|
//| with busio.I2C(SCL, SDA) as i2c:
|
|
//| i2c.scan()
|
|
//|
|
|
//| This example will initialize the the device, run
|
|
//| :py:meth:`~busio.I2C.scan` and then :py:meth:`~busio.I2C.deinit` the
|
|
//| hardware.
