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 .
