Use the Timeout interface to set up an interrupt to call a function after a specified delay.; You can create any number of Timeout objects, allowing multiple outstanding interrupts at the same time.

jimbaud 0:7a0f7fbc736b 5 Warnings and notes
jimbaud 0:7a0f7fbc736b 6 Timers are based on 32-bit int microsecond counters, so they can only time up to a maximum of 2^31-1 microseconds (30 minutes). They are designed for times between microseconds and seconds. For longer times, you should consider the time() real time clock.
jimbaud 0:7a0f7fbc736b 7 No blocking code in ISR: avoid any call to wait, infinite while loop or blocking calls in general.
jimbaud 0:7a0f7fbc736b 8 No printf, malloc or new in ISR: Avoid any call to bulky library functions. In particular, certain library functions (such as printf, malloc and new) are not re-entrant, and their behavior could be corrupted when called from an ISR.
