Jul 16, 2012 · As far as I understand your code, it will not work on a rollover. Let’s look at the case, where `counter` is close to rolling over (`counter = 250`) and `waitUntil` equals `counter`. `waitUntil` will be set to `waitUntil + interval == 250 + 47`. Because of rolling over, `waitUntil` will become `250 + 47- 256 = 41`.
