/****************************************************************************************************************************
Argument_None.ino
For NRF52 boards
Written by Khoi Hoang
Built by Khoi Hoang https://github.com/khoih-prog/NRF52_TimerInterrupt
Licensed under MIT license
Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
unsigned long miliseconds), you just consume only one NRF52 timer and avoid conflicting with other cores' tasks.
The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
Therefore, their executions are not blocked by bad-behaving functions / tasks.
This important feature is absolutely necessary for mission-critical tasks.
Based on SimpleTimer - A timer library for Arduino.
