OnTimer2

Name
OnTimer2 - Call a function at fixed interval

Description
Call a function at a fixed interval using Timer 2.
 * OnTimer2 works on all 8- and 32-bits boards.

The function is called indefinitely until Int.detach is called.

If Timer 2 is free, OnTimer2 will return the number of the interrupt, otherwise it will return "false".

Multi-call to OnTimer2 is not allowed. Function will then return "false" and produce "Error : interrupt TIMER2 is already used !" on the debug output.

If overwrite is needed, always use Int.detach with the interrupt number before new declaration.
