Millis() with int

Projects Programming
6

You can make yourself a "tiny millis timestamp" that can handle overflow just like its 'unsigned long' brother. Example:

unsigned int littleNow = millis()

subsequently, you can safely do things like:

unsigned int lastLittleNow;
...
if (littleNow - lastLittleNow >= interval) { ...

with the restriction than 'interval' can be no longer than 65535ms
