I updated the code and did some quick tests and it appears correct. Example #6 returns the same values for IDLE, but a few less ms when not compiled with IDLE. Using the setMillis() function in the SO posting, I did some quick tests with Example #2. using setMillis(-3000) sets the millis() value to 3 seconds before rollover. Task #1 gets an extra catch-up hit, but not Task #2. But, it works the same as the original code though when using setMillis(-3000). 2015-11-26T14:55:11+00:00 Anatoli Arkhipenko arkhipenko@hotmail.com 2015-11-26T14:55:11+00:00 urn:sha1:c07b4b58921bd3e6d91d8195809fadf292fc80a1 * packed three byte-long status variables into one byte-long bit array structure data type - saving 2 bytes per each task instance 2015-11-24T15:28:40+00:00 Anatoli Arkhipenko arkhipenko@hotmail.com 2015-11-24T15:28:40+00:00 urn:sha1:9edbe90155b19267bfb0cc4439ee5216f0569ba9 * incorrect calculation of next task invocation in case callback changed the interval * Task::set() method calls setInterval() explicitly, therefore delaying the task in the same manner 2015-11-18T16:19:32+00:00 Anatoli Arkhipenko arkhipenko@hotmail.com 2015-11-18T16:19:32+00:00 urn:sha1:85f6d7b0661035dbba835502129d487335872491 * bug fix: Task alignment with millis() for scheduling purposes should be done after OnEnable, not before.
