A Controller For Robotics And Microcontroller Applications Instruction

摘要

A controller board inspired by the Handy Board, but based on a pair of Atmel ATmega128's, is discussed. Elements of the hardware design and input/output interfaces are detailed, including parallel and serial I/O, analog I/O, an LCD interface, and dc motor control interfaces. Firmware for hardware drivers written in AVR assembly language and a handshaking protocol for communications between the microcontrollers are also discussed.
