-Arming sequence:
The figure below shows an example of throttle value versus time.
At power on, the ESC beeps 3 beeps.
When throttle signal is detected, it beeps one low tone beep. This signals the start of the arming
sequence. Then, when or if throttle is zero, it beeps one high tone beep. This signals the end of
the arming sequence.
Also, if 100% throttle is detected during the arming sequence, the ESC starts throttle calibration.
If the esc is armed and sees zero throttle for a given time, it beeps beacon beeps, which are
about a beep per three seconds.
-Input signal:
Available throttle calibration range is from 1000us to 2000us, and the difference between
minimum and maximum throttle must be more than 140us (70us in bidirectional mode). If a
calibration is done where the difference is less than 140us (70us), the maximum will be shifted so
that the difference is 140us (70us).
Oneshot125 mode works just the same as regular 1-2ms mode, the only difference is that all
timing is divided by 8. And the same for Oneshot42, where all timing is further divided by 3.
Multishot also works similarly, except the input signal range is 5-25us.
The input signal is always sampled with the MCU clock, at 24MHz or 48MHz.
