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
