Simple GPIO calculator for libgpiod based on its chardev.

Project description

Simple GPIO calculator for libgpiod based on its chardev using the formula chardev = (alphabet_index - 1) * 32 + pin which is also used on sysfs.


pip install git+


from gpio_calculator import Calculator

calculator = Calculator()

# Get chardev based on pin letter and pin number.
# Return should be 242
calculator.get_chardev("H", 18)

# Get chardev from list.
# Returns a list of converted items [242, 243, 244].
calculator.get_chardevs(["H18", "H19", "H20"])

# Get pin from chardev.
# Returns the pin number H18.

# Get all pins from chardevs.
# Returns all pins found H18, H19, H20.
calculator.get_pins([242, 243, 244])


All contributions, pull requests and comments are welcome!

When contributing it is important to test the module in order to make sure everything is working as expected. For that install dependencies to run the tests.

pip install pytest pytest-cov mock pylint

Running tests and see coverage.

py.test --cov -v --cov-config=.coveragerc --cov-report=html

This will generate a report with the coverage which is at 98% now, let’s try to keep it at the same percentage.
