gpio4

Control gpio in python on Linux.

Improved version based on Sysfs, features same as RPi.GPIO and gpio3

Support RaspberryPi / OrangePi / BananaPi...

Attention

Don't run this on your PC because gpios of computer are usually protected.

Installation

Install from PyPI is suggested.

pip install gpio4

Or install from source.

git clone git@github.com:hankso/gpio4.git
cd gpio4
python setup.py build && sudo python setup.py install

Usage

Want something like RPi.GPIO?

>>> import gpio4.GPIO as GPIO
>>> GPIO.setmode(GPIO.BCM)
>>> GPIO.setup([12, 13], GPIO.IN)
>>> GPIO.input([12, 13])
[0, 0]
>>> p = GPIO.PWN(12) # it will automatically setup this pin to output first
>>> p.start(30) # duty cycle is 30%
...
>>> from gpio4.constants import BOARD_NANO_PI as BOARD
>>> GPIO.setmode(BOARD)
>>> GPIO.setup([6, 7, 9], GPIO.OUTPUT)
>>> GPIO.output([6, 7, 9], [GPIO.HIGH, GPIO.LOW, GPIO.HIGH])
>>> GPIO.add_event_detect(8, GPIO.RAISING, bouncetime=300)

or call functions as you are using Arduino?

>>> from gpio4.arduino import *
>>> pinMode(13, OUTPUT)
>>> pinMode(12, INPUT_PULLUP)
>>> digitalWrite(13, HIGH)
>>> digitalWrite(13, digitalRead(12))
>>> shiftIn(dataPin=12, clockPin=13, bitOrder=MSBFIRST)
170

Try the most basic but fastest Sysfs class

>>> from gpio4 import SysfsGPIO
>>> from gpio4.constants import BOARD_ORANGE_PI_PC
>>> pin_name = 6
>>> pin_num = BOARD_ORANGE_PI_PC[pin_name]
>>> pin = SysfsGPIO(pin_num)
>>> pin.export = True # regist pin through sysfs, same like pinMode()
>>> pin.direction = 'out' # same like pinMode()
>>> print(pin.value) # current level
>>> pin.value = 1 # same like digitalWrite()
>>> pin.export = False # clear this pin from sysfs

If you have any question on usage, it is strongly recommended to directly read well commented source codes. Also check kernel doc of sysfs, and this article.
