I/O Communication Library

Project description

ahio is a communication library whose goal is to abstract the interfacing with various I/O hardwares, so that changing hardware becomes possible with minimum code modification. It’s desired that an application that already works with an I/O hardware will only need pin remapping and possibly initial setup change to work with another hardware, not entire code rewrite.

It works with drivers, which are installed in the ahio.drivers package. Every driver must implement the API described in the ahio.abstract_driver package. If you plan to use this library or develop a driver, read the documentation there.


Simplest way is to use pip: pip3 install ahio Alternatively you can checkout this repository and run python3 install

Basic usage

# Import the package:
import ahio

# You can see what drivers are available in this platform by calling

# Instantiate the desired driver
with ahio.new_driver('Arduino') as arduino:
  # The driver can have a driver-specific setup function. Call it as/if needed.

  # Map the pins. From now on, when you use 1 in the API, it will have effects
  # on pin D3 in the Arduino. If you change hardware in the future, just change
  # the mapping.
  arduino.map_pin(1, arduino.Pins.D3)
  arduino.map_pin(2, arduino.Pins.D13)
  arduino.map_pin(3, arduino.Pins.A1)

  # Change a pin direction (Input or Output)
  arduino.set_pin_direction([1, 2], ahio.Direction.Output)
  arduino.set_pin_direction(3, ahio.Direction.Input)

  # Set the output of a pin
  arduino.write([1, 2], ahio.LogicValue.High)
  arduino.write(1, 0.4, pwm=True)

  # Read the input of a pin
