<div dir="ltr">Hello Doug. Thanks for the additional information. I looked at the how-to information on the web page but frankly, it scared me off.... I don't understand enough about what I'm reading to even know where to begin. It's not a lack of information, but rather a lack of understanding on my part. I'll go back and re-read everything again and see if it sinks in a little better on the second or third read through. <div><br></div><div>There are two of us who are embarking on a control project - the other ham is just getting started. He's awaiting delivery of his first DMK URI. He has a far-better engineering background than I, but he's not at all familiar with Linux. Once we get his node on the air, then we will both be asking a lot of questions, I'm sure. Many thanks to you and everyone on the list for your patience and willingness to help others. </div><div><br></div><div>John</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Dec 18, 2015 at 12:34 PM, Doug Crompton <span dir="ltr"><<a href="mailto:doug@crompton.com" target="_blank">doug@crompton.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

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 <a href="http://hamvoip.org" target="_blank">hamvoip.org</a> 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.<br><br>Just remember that direct Pi GPIO is 3.3 volts! <br></font><br><b><font style="font-size:16pt" size="4">73 Doug</font><font style="font-size:16pt" size="4"><br></font><font style="font-size:16pt" size="4">WA3DSP</font><font style="font-size:16pt" size="4"><br></font><font style="font-size:16pt" size="4"><a href="http://www.crompton.com/hamradio" target="_blank">http://www.crompton.com/hamradio</a></font></b><font style="font-size:16pt" size="4"><br></font><br><br><div><hr>From: <a href="mailto:wb5nfc@gmail.com" target="_blank">wb5nfc@gmail.com</a><br>Date: Fri, 18 Dec 2015 10:26:14 -0500<br>To: <a href="mailto:arm-allstar@hamvoip.org" target="_blank">arm-allstar@hamvoip.org</a><br>Subject: [arm-allstar] How To for using GPIO on the DMK URI?<br><br><div dir="ltr">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? <div><br></div><div><br>Thanks!</div><div><br></div><div>John </div></div>
