/* NOTE:
The IF482 Generator needs an high precise 1 Hz clock signal which cannot be
acquired in suitable precision on the ESP32 SoC itself. Additional clocking
hardware is required, ususally the clock signal is generated by external RTC or
GPS chip or a GPS chip which can generate a precise clock signal (+/- 2ppm). In
this example code we use a Maxim DS3231 RTC chip, and configure it's interrupt
output as clock output. The clock signal triggers an interrupt on the ESP32,
which controls the realtime output of IF482 telegram. This is why code in
GPS which can generate a precise time pulse signal (+/- 2ppm).
In this example code we use a Maxim DS3231 RTC chip, and configure the chips's
interrupt output pin as clock. The clock signal triggers an interrupt on the

IF482.cpp depends on code in RTCTIME.cpp.
