Now go download. Make that LED blink in pure Assembly. You'll never look at digitalWrite() the same way again. Last updated: 2025. Toolchain versions change, but the GNU assembler for AVR has been stable for 15+ years. If a link is dead, search for "avr-gcc" on your OS's package manager. RESET: ; Set PB5 as output sbi DDRB,

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. Last updated: 2025
