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

Simple LED Blinker for Galileo

positional arguments:
  pinNumber      Specify the pin number, i.e. 0-13

optional arguments:
  -h, --help     show this help message and exit
  --count COUNT  Number of times to execute, default infinity
  --delay DELAY  Number of seconds to wait between readings, default 10
  --version      show program's version number and exit
