ARM assembler

Vilken assembler passar till följande kod:

int square(int num) {
   register int temp;
   register float x;
 
   temp =  4;
   x = 3.1415;
    
   return temp + (int) x;
}

Labb 2 - Blinky LED etc etc

• You can draw some awesome diagrams in fritzing, but you can *NOT* simulate i.e. make the LED blink
• Physical device programmed with web-based compiler
