I received my Chameleon AVR dev-kits yesterday and immediately started going through the manual. On top of processor-specific data sheets, e-books, sample code and other documents there is a ~300page manual written specifically on the Chameleon design and operation. The Chameleon comes pre-loaded with a little test application/game. I decided to film it briefly in order to demo what the board is capable of. Here is the default game displayed on a TV via NTSC, audio is through the TV but the mic on my camcorder isn’t great so it’s a bit low and input to the game was via PS2 keyboard.

Chameleon Invasion

So I’ve been on quite the shopping rampage lately ordering some parts, several books and I just now ordered a few new dev. kits that I can’t wait to play with! As I was reading my new issue of Circuit Cellar I saw an article about a development board that contains an Atmel AVR 328P *AND* a Parallax Propeller. I’ve been wanting to play with the propeller for quite some time now, but just never got around to ordering one. The board is from Nurve Networks and it is called the Chameleon.

I should also note that it also comes with a PIC in place of the AVR, but the fact that the AVR comes pre-loaded with the Arduino bootloader and that there are already Arduino libraries for the platform looks really interesting! I have ordered two boards and I think I’m going to try an experiment to create the same project on both boards, one using the Arduino bootloader/IDE/libraries and one without to post a comparison of the time required to complete each.

Some of the board’s features include:

  • 2 Processors for a total of 9 processing cores
  • 1MB Flash, 64K EEPROM
  • NTSC/PAL video output as well as VGA interface
  • Audio out
  • PS2 port for interfacing with keyboard/mouse

Take into account that the entire package is currently going for less than $60 and it looks even more impressive. As always, I’ll post on any projects/experiences once I get them in 😀

Cheers!
