Nous avons obtenu un code launch.hex avec naken_asm
naken_util -msp430 launch.hex
ici nous allons utiliser le msp430 (par défaut si on ne le précise pas)

continuer à avancer de pas en pas et voir comment se comporte notre programme
on peut modifier les registrer
stopped> set r9=0x0003
Register r9 set to 0x0003.
run va lancer notre programme au ralenti (speed en hz) et une animation va nous montrer ce qu'il se passe dans une bête comme le msp430
