Hobby robotics and programming of the Atmel AVR series of micro controllers. Larry Barello is a designer of embedded processors for industrial, medical and communications industries.
Small real time operating system RTOS called AvrX, short for AVR Executive. he latest is tuned to work with the GNU and IAR C compilers.
Spring 2000, I decided to rebuild Dilbert on a printed circuit board using the Atmel AT90S8535 processor. This processor is very much like the 8515 in Dilbert with three significant exceptions: it contains an on-board 8 channel 10 bit A/D, it doesn't have memory expansion capability and there is a separate RTC timer/clock circuit.
