#Python For Firefly Port

fireflyP is designed for using devices port on firefly or other similar platforms.It can support RK3399 now. Like GPIO .

NOTE: fireflyP is still in development. if you find something wrong, please let me know, and if you fix bugs, it is nice to give me 'Pull requests'

##Install fetch source code:

$ git clone https://github.com/zhansb/pyFireflyP.git
$ cd pyFireflyP

install python modules(python can be python2 or python3):

$ sudo python setup.py install

##Usage GPIO and PWM control regs directly by devmem in fireflyP, and independent of kernel space.

The devmem source is modifed from pydevmem (Thanks to Kyle).

You need root privilege to execute it!

###Gpio ####Interface: init() Init GPIO function implement it before using Gpio get_level(self) Returns the level of the pin for input direction or return setting of the DR register for output gpios.

set_dir(self, dir)
    set GPIO direction
    :dir: refer to GpioDir

set_drv(self, drv)
    set GPIO drv
    :drv: refer to GpioDrv

set_level(self, level)
    set GPIO output signal
    :level: refer to GpioLevel

set_mux(self, mux)
    set GPIO mux
    :mux: refer to GpioMux

set_pull(self, pull)
    set GPIO pull
    :pull: refer to GpioPull
en_clk(self)
    enable GPIO CLK
	GPIO0-1 0x0104
	GPIO2-4 0x037c

####Example for turn on/off the yellow led on firefly-rk3288: $sudo python >>> from fireflyP import Gpio >>> Gpio.init() >>> LED_YELLOW="GPIO8A2" >>> led_yellow=Gpio(LED_YELLOW) >>> led_yellow.set_dir(Gpio.OUTPUT) #set_dir have contained set_mux(GpioMux.MUX_GPIO) >>> led_yellow.set_level(Gpio.LOW) #turn on the yellow led >>> led_yellow.set_level(Gpio.HIGH) #turn off the yellow led
