Thank you for the input guys.
to get the result in microseconds. (but it SHOULD be 1000000
Thanks johnerrington, in my haste to transpose from my laptop to desktop, I miss counted zeros. I've updated that and the usage of the word double rather than unsigned long.
I hadn't thought about the fact that the 1000000 is larger than what could be stored in a standard int or float. I'll swap that over to UL and simplify the equation to
cycle_time = 1000000UL / frequency; This looks to be the most simple solution. I'll post my results.
As a side question, when asking for assistance in something this simple, is it better etiquette to post only the necessary code as I did here, or the entire sketch, of nearly 200 lines, which has been properly commented?
Thank you guys again.
