libgpiod python ctypes binding

GPIO NEXT

This is a python ctypes binding for libgpiod.

It's time to switch from the GPIO sysfs interface to gpiod to the linux GPIO character device (gpiod, stands for GPIO device)

Since linux 4.8 the GPIO sysfs interface is deprecated. User space should use the character device instead. This library encapsulates the ioctl calls and data structures behind a straightforward API.

Requirements

• libgpiod1

Install

sudo apt install libgpiod1
pip install gpio-next

Usage

1. turn on/off an LED

import time
from gpio_next import Output

LED = Output(64, default_value=0)
for i in range(10):
    LED.write(i & 1)
    time.sleep(1)

2. detect button events

from gpio_next import Input

button = Input(203)

for i in range(10):
    print(button.wait())
    print(button.read())
