Code for only first part of the slope dimming leds

Hi Guys,
Can someone help me to a code where I need my actinic channel ramping up from 3% to 20%, starting at 8am, ending at 9am.
Same for the ramping down , lets say start at 20% down to 3%, from 10pm to 11 pm.
All I can find is is full parabola's and slopes. I just need the ramping up parts and ramping down parts.
If you guys can help me out here, that would be great.
Thanks in advance,
Leslie

That's what the slope does

Hi Roberto,
From my understanding of the slope is that it will ramp up (in my example) to 20% and stay on 20% until 10pm and then ramp down.
That is not what I need. I would like the leds ramp up to 20% in an hour and ramp down at the end. I don't need the middle part of the slope.
The middle part will be taken care of by another rule.
Hope this is a little bit more clear.

So do the normal slope and then add a statement after that to set those channels to 0%.

Dear Lee,
This is way above my knowledge. But I give it a try.
Is it something like this for the ramping up part?
ReefAngel.PWM.SetActinic( PWMSlope(8,0,0,0,3,20,60,0) );
The way I read the above is at 8am it starts ramping up to 20% for 60 minutes and then it stays at 20% until 11pm, then it ramps down to 3% for 60 minutes.
I am confused.

Yes that looks good for the slope.
Now you need a statement between 9 and 11 to set the channel to 0.
if (hour()>=9 && hour()<23) ReefAngel.PWM.SetActinic(0);

Dear Lee or Roberto,
ah I see. So the following below is my piece of code, I verified it, which was ok. I changed the values and times a bit, but I am not sure if it is going to do what I want it to do.
all those brackets and equal signs really get me confused. Would you mind having a look at it?
What I want to accomplish is:
*8.30 am actinic ramping up to 20% for 60 minutes
* then the parabola rules take it over until 21.30
* then at 21.30 actinic ramping down to 0% for 60 minutes
Thanks in advance.

Code: Select all
if (( hour()>=9) && (minute()>30) && ( hour()<=21) && (minute()<30) )
{
ReefAngel.PWM.SetDaylight( PWMParabola(9,30,21,30,3,30,0) );
ReefAngel.PWM.SetActinic( PWMParabola(9,30,21,30,20,50,0) );
}
else
ReefAngel.PWM.SetActinic( PWMSlope(8,30,22,30,0,20,60,0) );
