+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:
+
+* **analogio** - analog 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
+* **keypad** - support for scanning keys and key matrices
+* **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)
+* **rainbowio** - provides the colorwheel() function
+* **usb_hid** - act as a hid-device using usb_gadget kernel driver
+
+For details, see the `Blinka API reference
+<https://circuitpython.readthedocs.io/projects/blinka/en/latest/index.html>`_.

 
 

-This repository contains a selection of packages mirroring the CircuitPython API
-on hosts running micropython. At the time of writing drafts exist for
+Dependencies
+=============

 
 

-* board - breakout-specific pin identities
-* microcontroller - chip-specific pin identities
-* digitalio - digital input/output pins, using pin identities from board/microcontroller
+The emulation described above is 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* CPython/Micropython+compatibility layer to prove conformance.

 
 

-Dependencies
-=============
+Installing from PyPI
+=====================
+
+On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
+PyPI <https://pypi.org/project/Adafruit-Blinka/>`_. To install for current user:
+
+.. code-block:: shell
+
+    pip3 install Adafruit-Blinka
+
+To install system-wide (this may be required in some cases):

 
 

-The Micropython compatibility layers described above are intended to provide a CircuitPython-like API for devices which
-are running 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.
+.. code-block:: shell
+
+    sudo pip3 install Adafruit-Blinka

 
 

-However, the test suites under *testing.implementation.all* are by design
-intended to run on either CircuitPython or on Micropython+compatibility layer to prove conformance, while the test suites under *testing.implementation.micropython* will only run
-on Micropython and *testing.implementation.circuitpython* will only run on CircuitPython
+To install in a virtual environment in your current project:

 
 

+.. code-block:: shell
+
+    mkdir project-name && cd project-name
+    python3 -m venv .env
+    source .env/bin/activate
+    pip3 install Adafruit-Blinka

-the following sequence runs through some basic testing of the digitalio compatibility layer.
+The pin names may vary by board, so you may need to change the pin names in the code. This
+example runs on the Raspberry Pi boards to blink an LED connected to GPIO 18 (Pin 12):

 
 .. code-block:: python
 
 
 .. code-block:: python
 

-    import testing
-    testing.main()
+    import time
+    import board
+    import digitalio
+
+    PIN = board.D18
+
+    print("hello blinky!")
+
+    led = digitalio.DigitalInOut(PIN)
+    led.direction = digitalio.Direction.OUTPUT

 
 

+    while True:
+        led.value = True
+        time.sleep(0.5)
+        led.value = False
+        time.sleep(0.5)
