A Simple Intel Galileo LED Control Script in Python

I had a bit of trouble finding information on blinking an LED on the Intel Galileo Gen 2 using python and wanted to share a script that blinks an LED.

This uses MRAA to perform all the real tasks.

Which does the following:

Initialize the pin

pin = mraa.Gpio(X) # where X is the pin number

Set it to output mode

pin.dir(MRAA.DIR_OUT) 

Turn it on or off (0/1)

pin.write(1) # Turn on
pin.write(0) # Turn off

But it is just wrapped in a script which will do this for you.

Simple use:

root@galileo:~# ./led.py 1 
Blinking LED 1
Using delay 10 and for 0 attempts
Turning LED 1 on, for 10 seconds, count 0.

root@galileo:~ ./led.py --help
usage: led.py [-h] [--count COUNT] [--delay DELAY] [--version] pinNumber
