July Linkdump
Yes, it’s that time again when we round up and post some of the cool stuff out there on the interwebs:
- First, check out this remarkable movie of Robot Arm Clocks. The creativity and resourcefulness shown in this project is astounding– look at all the different kinds of clocks that they made– holy cow.
- Those of you who are into AVRs and LEDs (you know who you are) might like to look at this page of LED games. It’s in Japanese, but worth the effort to look. (You can always cheat and translate it too.) Source code is there for the downloading, kits are available– in Japan at least– and there’s also an alpha-stage version of BASIC for AVR there too.
- Those of you who are not into AVRs and LEDs, but want to be, please check out Ladyada’s new, extensive, and growing AVR tutorial.
- Next, get yourself an RC Predator kit. Includes digital camera.

Resources for getting started with AVRs
This is a short list of resources for getting started with AVR microcontrollers. It’s intended as a supplement to intro AVR classes that we have given. We intend to periodically update this list; leave your suggestions for additions in the comments, please. (Last update: October 2012)
First of all, these GUI installers for the GNU AVR toolchain are really excellent: Two flavors for Mac and Windows:
CrossPack (Mac – recommended solution)
MHV AVR Tools (Windows – recommended solution. Also available for Linux and Mac)
On Linux and Unix-like operating systems (Macs included) you can also follow the directions given by bdmicro (330 kB PDF) for installing the components one at a time.
Almost certainly the best place to get started is at Ladyada’s AVR tutorial. It is extensive and up to date, and it will probably be kept up to date better than most of the other resources that we mention here.
A couple of other sets of instructions and reference guides:
- Sparkfun guide to embedded electronics, part I.
- Programming AVR Microcontrollers on a Macintosh (Getting Started)
- Programming an AVR microcontroller using OS X
- MacAVR (Mac)
- The AVR Instruction Set (688 kB PDF), for those occasions when you need to assemble.
- Diagram of the GNU AVR toolchain
- AVR-libc user manual. Might want to jump right to the module list.
- The incredibly awesome online AVR fuse calculator! No more calculating fuse bytes by… um… calculator.
- AVRfuses fuse-programming application. Pretty sweet, cross platform.
Some notes on hardware:
- The AVR “Ghetto Programmer” – cheap, if you have a parallel port.
- PopSci teaches you how to take the The AVR Dragon programmer/dev board and make it actually useful.
- Useful list of AVR development tools at BDMicro
A few interesting examples of AVR source code:
- TV-B-Gone, the open-source version.
- Gobs of other good examples at Ladyada.net
- Procyon AVRlib by Pascal Stang. Open-source C libraries to do all kinds of things– some quite advanced.
