The Si5351 library for avr-gcc that I’ve been promising for the last four posts is finally in a state where I feel comfortable releasing it, so I’ve posted it on GitHub. I think that the documentation posted on the README file and inside the code should be enough to get you going, but if you… Read More Si5351A Investigations Part 5
As a world-class procrastinator, I know I’m very late with this post only about 12 hours before the event. However, I still wanted to share it with you in the hopes that maybe it could help one person. As you may have heard, the Juno spacecraft will be making a close approach to Earth on… Read More Hi Juno!

Also known as “The slowest implementation of the Game of Life in 2013″. This is what happens when you have insomnia. [pe2-image src=”http://lh3.ggpht.com/-pIMUUJNK__k/URzHojTQSAI/AAAAAAAACxQ/MCZeLIlpebE/s144-c/IMG_20130214_031548.jpg” href=”https://picasaweb.google.com/100175922620194527589/InstantUpload#5844765915904755714″ caption=”IMG_20130214_031548.jpg” type=”image” alt=”IMG_20130214_031548.jpg” ] What I did was first clear out the entire world, then place a plane of glass across the entire world at y=1. The actual Life cells are… Read More Conway’s Game of Life in Minecraft Pi Edition
If you are a Raspberry Pi enthusiast, you may have seen that Minecraft Pi Edition was officially released yesterday. I don’t have the time to game like I used to, so I haven’t really played Minecraft, but this version looked intriguing since it’s free and it has an open API. So I downloaded it yesterday… Read More Exploring Minecraft Pi Edition
A few quick updates to the avs3a software that I’ve writting for the Avnet Spartan-3A Eval Kit (as mentioned in a previous post). First, many thanks to George Gallant from the Avnet Spartan-3A Eval Kit mailing list for rewriting the code to fix the horrible configuration time, as well as for the many error checking… Read More avs3a Google Code Page
As I mentioned on the Avnet Spartan-3A Eval Kit Google Group, I’ve created a C program that will allow you to configure the FPGA via your Linux box. I don’t have a lot of time to elaborate on how to use this program, but the basic steps are listed below. These instructions assume that you… Read More Configuring the Avnet Spartan-3A Eval Board on Linux (Alpha)
Completely by accident, I happened to stumble upon a program that gives you an easy way to learn DSP techniques by focusing on the underlying algorithms and not the hardware details. The program is called BasicDSP and is available as a Linux source tarball or Windows executable. BasicDSP was created by PA3FWM and PE1OIT as… Read More Learning DSP Concepts with BasicDSP
Lately, I have been using my Ubuntu Hardy Heron box for coding and programming my AVR projects using the simple combination of gedit, the avr-gcc toolchain and the USBtinyISP. It’s a little bit of a pain to get set up correctly, but it works very well once it’s up and running. I’ve been pretty happy… Read More Programming AVR Microcontrollers in Eclipse
