[arm-allstar] How To for using GPIO on the DMK URI?

[Doug Crompton]

John,

 While the sound USB FOB extra GPIO bits are there and can certainly be used don't be afraid of the Pi GPIO. The howto is on the web page as well as a project that uses USB to create GPIO. Both definitely work and if you need more bits that would be the way to go. The Pi I/O using WiringPi is built-in to the hamvoip.org Pi image. Any of these methods can be used via scripts and Allstar. I use the USB GPIO project shown in how-to's on the web page at my Allstar demos, setting and resetting bits controlling relays via DTMF.

Just remember that direct Pi GPIO is 3.3 volts!

I'm just beginning to look at using some of the GPIO functions available in the Rpi2 / DMK URI. Looks like there are LOTS of different ways to accomplish the same task. To get started, I'd like to keep things as simple as possible. Really don't want to use the Pi's GPIO pins or an outboard USB device. Can someone point me in the right direction for information on controlling the URI's GPIO pins 1, 2 & 4? 

Thanks!
John
