Now assemble it using GNU toolchain:

AVR Assembler is the lowest level of human-readable code for Atmel (now Microchip) AVR microcontrollers—the brains inside Arduino Uno (ATmega328P), Nano, and many custom boards. While most people use Arduino's C++ environment, learning Assembly gives you absolute control over every clock cycle, every register, and every byte of memory.
