GPIOs as Services

---

Hey guys, I put this simple package together which allows you to turn on and off GPIOs from the command line as services. This can be used for all sorts of things.



Instructions:
1. Download this package http://forum.xda-developers.com/atta...1&d=1362453406
2. unTar.Gz it to the root directory of your Raspberry Pi. There's 6 files which go into /etc/init.d. The files are InitGPIO, led0, led1, led2, led3, and led4. These services control GPIOs 0, 1, 4, 14, and 15. See the chart below for more information.
3. Connect LEDs with 100 ohm resistors to the corresponding GPIOs using an old IDE hard disk cable.

Use
Initialize the GPIOs first

service InitGPIO start

Turn on LEDs with

service led0 start
service led1 start
service led2 start
service led3 start
service led4 start

Turn off LEDs with

service led0 stop
service led1 stop
service led2 stop
service led3 stop
service led4 stop

Great job! This will be useful!

Seems like a neat solution. How fast can you toggle the pins? I can check with a scope if you haven't already .

Edit: It hit me that I could just look at the source, doh. As it's using echo you should get about 3.4khz.

I haven't checked.

Have you already posted specs and software for your "Root All The Things Box" if not, are you going to as I'd like to build one myself.

I saw the root box on xda-tv. Looks great!

thanks for the services I wanted to test some things with the GPIOs (controlling a DC motor with an H-bridge) and I was to lacy to do the python programming so your binary were really convenient

Thanks for your work :thumbup:
Just to confirm, can I use this to control DC motors instead of leds? and if so do I have to change anything?

You would want to use transistors or relays to drive them.

This will be handy while I figure out just what I can use my spare Pi for...
