I took my test code from my previous PI post and made a few changes to make things easier to read and use. This tutorial shows the functions, how to use them, and then demonstrates how to add functions to BASH memory so that they can be called quickly and easily without clogging up your scripts.

Reading and Writing to the RasPi GPIO using BASH
I’ve finally taken some time to play with my Pi after getting some of the peripherals to work. I struggled getting the sound to work, but finally found a post that described what to do. I’d like to point out that I’m still using Debian Squeeze. That might be where some of my issues stem from.
Raspberrypi.org has the latest downloads, and many of the bugs that I deal with are probably solved by now in newer distributions.
What I have done is taken the time to play with the GPIO port using a Bash script. My Bash skills are not top notch, but with a little searching I can usually get things done. Here’s what I discovered using my simple Bash script. Continue reading
Last night I finally put the radio in the shack. I had to take it from the Jeep. I should have a second Yaesu FT-1900 by middle of next week. Continue reading
Recently I have been messing with APRS and other packet radio transmissions, and I haven’t really found it to be all that enjoyable in its present form. Don’t get me wrong. I have had plenty of fun with it, but it hasn’t been what I want to do. My previous articles about getting Xastir up and running and sending packets through the ISS show that I enjoyed what I was doing, but the problem is that neither situations were very convenient. With APRS, I had to start up a laptop and initialize the TNC or I had to keep it running and risk killing the car battery. With the ISS I had to be ready to go at a moment’s notice, and since many of the passes were during work hours, I was not able to leave and drive to the clearing to make contact. Now, I think I’ve come up with a solution. Continue reading
