Formulas
●
Length of 1-signal = PWM period * (PWM Input - PWM input minimum) / (PWM input
maximum - PWM input minimum)
●
Length of 0-signal = PWM period - Length of 1-signal.
Note
The shortest signal duration for 0 and 1 is 0.1 s in each case.
If the calculation yields a duration for the 1
-signal of less than 0.1 s, the output remains 0,
and if a duration for the 0
-signal of less than 0.1 s is calculated, the output remains 1.
