Little Micro Makes Big Flash

July 21, 2005

Atmel's latest 8-bit ATmega AVR microcontrollers are designed for large, low-power applications. The smallest part is the 64-pin ATmega 2561. The AVR's 32 register file is great for C programming. The chip also can wake up interrupts on up to 32

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
