gpio4 0.0.2

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

# gpio4 Python module to control gpio on Linux.

Improved gpio module 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 CPU are usually protected.

# Installation Install from PyPI is suggested.

`bash pip install gpio4 `

Or install from source.

`bash git clone [e-mail]:hankso/gpio4.git cd gpio4 python setup.py build && sudo python setup.py install `

# Usage Want something like RPi.GPIO?

`python >>> 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?

`python >>> 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?

`python >>> 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 source codes, which are well commented. Also check [kernel doc of sysfs](https://www.kernel.org/doc/Documentation/gpio/sysfs.txt), and [this article](https://www.acmesystems.it/gpio_sysfs).
