Improved gpio module based on Sysfs, features same as RPi.GPIO and gpio3
Project description
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.
