how to calc. the period/freq. from array

i have an array of samples taken for square wave and i need to calc the period from this array

any tips?
 

I think FFT is more precise

That really depends on the number of samples, sample rate, etc..

Looking at zero-crossings takes less resources. It all depends on what is really required. If this is being done on a computer, then use an FFT; if it's being done in an FPGA, then maybe a different approach makes more sense.
