   The ESP32 has two timer groups, each one with two general purpose hardware timers. All the timers
   are based on 64 bits counters and 16 bit prescalers
   The timer counters can be configured to count up or down and support automatic reload and software reload
   They can also generate alarms when they reach a specific value, defined by the software.
   The value of the counter can be read by the software program.

   Now these new 16 ISR-based PWM servo contro uses only 1 hardware timer.
   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.

   Notes:
   Special design is necessary to share data between interrupt code and the rest of your program.
   Variables usually need to be "volatile" types. Volatile tells the compiler to avoid optimizations that assume
