  Welcome to "IST-4-ASM" where you will learn to program in assembly. This course has no theoretical prerequisites and relies fully on hands-on learning. So please bring your laptop with you (and install python3 if it is not done already).

  For all questions and demands, please e-mail us both: lionel.morel@insa-lyon.fr + guillaume.salagnac@insa-lyon.fr. Thanks !
