: Direct port manipulation to build "Cylon Eyes" (LED scanners) .
The book's primary goal is to teach "bare-metal" or register-level programming . While Arduino provides convenient libraries (like digitalWrite() ), they add overhead. Williams teaches you to: Make: AVR Programming: Learning to Write Softwa...
by Elliot Williams is a definitive guide for makers who want to move beyond the Arduino IDE's abstractions and program Atmel’s AVR microcontrollers at the register level . Published by Maker Media/O'Reilly in 2014, it remains a highly-rated resource for those seeking to "squeeze" more performance and efficiency out of 8-bit chips like the ATmega328p .
