GPIO_Calculator

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

Installation

pip install git+https://github.com/yeyeto2788/GPIO_Calculator

Usage

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.
calculator.get_pin(242)

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