+This repository contains a selection of packages emulating the CircuitPython API
+for devices or hosts running CPython or MicroPython. Working code exists to emulate these CircuitPython packages:
-* **board** - breakout-specific pin identities
-* **microcontroller** - chip-specific pin identities
* **analogio** - analog input/output pins, using pin identities from board+microcontroller packages
-* **digitalio** - digital input/output pins, using pin identities from board+microcontroller packages
* **bitbangio** - software-driven interfaces for I2C, SPI
+* **board** - breakout-specific pin identities
* **busio** - hardware-driven interfaces for I2C, SPI, UART
+* **digitalio** - digital input/output pins, using pin identities from board+microcontroller packages
+* **microcontroller** - chip-specific pin identities
+* **micropython** - MicroPython-specific module
+* **neopixel_write** - low-level interface to NeoPixels
* **pulseio** - contains classes that provide access to basic pulse IO (PWM)
+* **pwmio** - contains classes that provide access to basic pulse IO (PWM)
For details, see the `Blinka API reference
<https://circuitpython.readthedocs.io/projects/blinka/en/latest/index.html>`_.
Dependencies
=============
-The Micropython compatibility layers described above are intended to provide a CircuitPython-like API for devices which
-are running CPython or Micropython. Since corresponding packages should be built-in to any standard
-CircuitPython image, they have no value on a device already running CircuitPython and would likely conflict in unhappy ways.

The test suites in the test/src folder under **testing.universal** are by design
-intended to run on *either* CircuitPython *or* Micropython+compatibility layer to prove conformance.
