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


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
