PWM: Examples in practice
In this chapter we give you two examples, how to write values in the PWM regis-
ters. All values have to be written in microseconds (μs) in the PWM registers,
therefore remember always the factor 10
-6
s.
Example 1:
Set PWM with 1kHz at 30% pulse width.
Example 2:
Set PWM with 250 Hz at 12% pulse width.
Formula 2: PWM example 1
Formula 3: PWM example 2
