Example:
When the target is
detected, the OUT pin
outputs a high level signal
(100% duty cycle);
otherwise, it outputs a low
level signal (0% duty
cycle).
When the target is
detected, the OUT pin
outputs a high level signal
(100% duty cycle);
otherwise, it outputs a low
level signal (0% duty
cycle). The transition is
completed over a period of
1.984 seconds
(approximately 2 seconds).
The OUT pin outputs a low
level signal (0% duty
cycle) when the target is
detected; otherwise, it
outputs a high level signal
(100% duty cycle).
When the target is
detected, the OUT pin
outputs a PWM signal with a
duty cycle of 90%;
Duty cycle of OUT pin signal output when no target is
detected: Value range from 0 to 100.
Duty cycle of OUT pin signal output when a target is
detected: Value range from 0 to 100.
Time required for the duty cycle to transition from par1 to
par2: Value range from 0 to 255. Corresponding time value is
par3*64ms. Note: If par3=20, then the transition from par1 to
par2 will take 20*64ms=1.28s.
