How many clock cycles does a"for" loop take?

Raul77 over 4 years ago

Hello,

I work with cortex M3-Microcontroller (LPC1768) and I want to know how much clock has a loop (for)

for(i=0;i<1;i++);

Thanks

It depends.

But you can easily find out:

examine the generated code

run it in the simulator

Beware that any optimising compiler is liable to optimise-out any "useless" loops ...
