need help with dosing pumps

[Meshmez]

Ok, so im having trouble with setting up dosing pumps...

Here is what i want to do..
I want to be able to enter my TOTAL daily dosing time in the "runtime" memory spot.

I then want to have my calcium dose that amount evenly, hourly, over the 24hour day, with a 30 minute offset (so 12:30, 1:30, 2:30 etc) (runtime/24hr=hourly dose time.) so for instance if i want 60 minutes of dosing daily, i want calcium to dose 60min/24doses= 2.5min every hour.

What I want for my alkalinity is a little tougher. I want it to dose more at night than during the day. i want it to dose 1/3 of the total from 1PM-1AM, and 2/3 from 1AM to 1PM. I want to do this to try to help level my PH over night. I want it to dose every 30 min.

so from 1PM-1AM i want (60min/3)/24doses=0.83 minutes every 30 min.
and from 1AM-1PM i want ((60min/3)/24doses)*2= 1.66minutes every 30 min.

can i just do what i have below, with the runtime memory set to 3600sec? also, on the android app, which memory location corresponds to that runtime memory location?

// Dosing

//Calcium
ReefAngel.DosingPumpRepeat(Port1,30,60, int RunTime/24);

// Alkalinity

if ( hour() >= 1 || hour () <= 13 )
{
ReefAngel.DosingPumpRepeat(Port8,0,30, ((int RunTime/3)/24)*2);
}
else
{
ReefAngel.DosingPumpRepeat(Port8,0,30,((int RunTime/3)/24));




Sorry if im totally missing something here...

I'm afraid the dosing timer memory location is byte size and not int
Even though the function takes int size.
So, you would have to use a custom memory location. Is it ok?
Let's say you pick memory location 150 and store an int size value.
Then, you could use this:

Code: Select all

  // Dosing
  int RunTime = InternalMemory.read_int(15);
  //Calcium
  ReefAngel.DosingPumpRepeat(Port1,30,60, RunTime/24);

  // Alkalinity

  if ( hour() >= 1 && hour () <= 13 )
  {
    ReefAngel.DosingPumpRepeat(Port8,0,30, ((RunTime/3)/24)*2);
  }
  else
  {
    ReefAngel.DosingPumpRepeat(Port8,0,30,((RunTime/3)/24));
  }

ya using a memory location is fine, just wasnt sure how to do it, and i wasnt sure if i could do that math in the code or not.

I guess in that case i might as well take it one step farther and make it so i can just enter my dose amount in mL and add to the equation in the code to convert that to seconds. so i could enter 100 for 100ml, and then in the code just add ((runtime/1.1)/60) since the pump is 1.1mL/min

to confirm, for location 150 the code is:
int RunTime = InternalMemory.read_int(15);

or was the (15) supposed to be (150)

so is that code basically just naming internal memory location 150 = "runtime" so when i enter runtime into the code it looks there for the int value?

It was a typo Good catch
You need this:

Code: Select all

int RunTime = InternalMemory.read_int(150);

Great, Ill give it a shot tonight.

Thanks for the quick response as always Roberto!
