+   STM32TimerInterrupt.h
+   For STM32 boards
+   Written by Khoi Hoang
+
+   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 Hardware 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.

+/****************************************************************************************************************************
+   STM32TimerInterrupt.h
+   For STM32 boards
+   Written by Khoi Hoang
+
+   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 Hardware 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.
