This package provides class to control the GPIO on Allwinner sunxi platform. Current release does no support any peripheral functions.

Example

Typical usage::

#!/usr/bin/env python

import SUNXI_GPIO as GPIO

#init module
GPIO.init()

#configure module
GPIO.setcfg(GPIO.PIN#, GPIO.OUT)
GPIO.setcfg(GPIO.PIN#, GPIO.IN)
    
#read the current GPIO configuration
config = GPIO.getcfg(GPIO.PIN#)

#set GPIO high
GPIO.output(GPIO.PIN#, GPIO.HIGH)

#set GPIO low
GPIO.output(GPIO.PIN#, GPIO.LOW)

#read input
state = GPIO.input(GPIO.PIN#)

#cleanup 
GPIO.cleanup()

SPI usage::

#import SUNXI_SPI as SPI

#init
SPI.init(mode)

#write
SPI.write(byte1, byte2, byte3, ....)

#read
SPI.read(address, byte1, byte2, byte3, ....)

Where modes are:

* 0 - POL=0 and PHA=0
* 1 - POL=0 and PHA=1
* 2 - POL=1 and PHA=0
* 3 - POL=1 and PHA=1
