One of the things I like most to do is use the wizard to generate some code then compare it to what I doing, looking for improvements, ideas, etc.

Roberto and I wrote this code to monitor a float valve in my display tank, when tripped would sound the buzzer, turn off the pump, then send an alert to the portal which would alert me via text, email etc.

Code: Select all

//turn off port 8 - main pump when switch is tripped and sound buzzer 
     ReefAngel.Relay.Set(Port8,ReefAngel.IO.GetChannel(0));
     ReefAngel.PWM.SetDaylight(100-(ReefAngel.IO.GetChannel(0)*100)); 
          
     //tell the portal we have a overflow problem
     ReefAngel.CustomVar[0]=ReefAngel.IO.GetChannel(0);
     ReefAngel.CustomVar[7]=1;

I am now going to be adding more float valves to my new tanks and need to replicate this to monitor more floats, different relay ports and pumps, etc. I found this piece of code on the wizard

Code: Select all

// Initialize Buzzer variables
byte buzzer=0;
byte iochannel0flag=0;
byte iochannel1flag=0;
byte iochannel2flag=0;
byte iochannel3flag=0;
byte iochannel4flag=0;
byte iochannel5flag=0;

void loop()
{
    iochannel0flag = ReefAngel.IO.GetChannel( 0 );
    iochannel1flag = ReefAngel.IO.GetChannel( 1 );
    iochannel2flag = ReefAngel.IO.GetChannel( 2 );
    iochannel3flag = ReefAngel.IO.GetChannel( 3 );
    iochannel4flag = ReefAngel.IO.GetChannel( 4 );
    iochannel5flag = ReefAngel.IO.GetChannel( 5 );
    buzzer = iochannel0flag + iochannel1flag + iochannel2flag + iochannel3flag + iochannel4flag + iochannel5flag;
    if ( buzzer >= 1 ) buzzer = 100;
    ReefAngel.PWM.SetActinic( buzzer );

Can I use this to do what I want, monitor several floats, effect several ports based on individual valves and expand on the original code? Thanks in advance.

So I am currently doing this:

Code: Select all

//turn off port 8 - DT pump when switch is tripped and sound buzzer 
     ReefAngel.Relay.Set(Port8,ReefAngel.IO.GetChannel(0));
     ReefAngel.PWM.SetDaylight(100-(ReefAngel.IO.GetChannel(0)*100)); 
    
//turn off port 7 - GT pump when switch is tripped and sound buzzer 
     ReefAngel.Relay.Set(Port7,ReefAngel.IO.GetChannel(1));
     ReefAngel.PWM.SetDaylight(100-(ReefAngel.IO.GetChannel(1)*100)); 
          
//tell the portal we have a overflow problem
     ReefAngel.CustomVar[0]=ReefAngel.IO.GetChannel(0);
     ReefAngel.CustomVar[1]=ReefAngel.IO.GetChannel(1);
     ReefAngel.CustomVar[7]=1;

And will be soon adding more float valves to do other things. I found this code using the wizard and wonder can I now do this:

Code: Select all

// Initialize Buzzer variables
byte buzzer=0;
byte iochannel0flag=0;
byte iochannel1flag=0;
byte iochannel2flag=0;
byte iochannel3flag=0;
byte iochannel4flag=0;
byte iochannel5flag=0;

void loop()
{
    iochannel0flag = ReefAngel.IO.GetChannel( 0 );
    iochannel1flag = ReefAngel.IO.GetChannel( 1 );
    iochannel2flag = ReefAngel.IO.GetChannel( 2 );
    iochannel3flag = ReefAngel.IO.GetChannel( 3 );
    iochannel4flag = ReefAngel.IO.GetChannel( 4 );
    iochannel5flag = ReefAngel.IO.GetChannel( 5 );
    buzzer = iochannel0flag + iochannel1flag + iochannel2flag + iochannel3flag + iochannel4flag + iochannel5flag;
    if ( buzzer >= 1 ) buzzer = 100;
    ReefAngel.PWM.SetDaylight( buzzer );

ReefAngel.Relay.Set(Port8,ReefAngel.IO.GetChannel(0));
ReefAngel.Relay.Set(Port7,ReefAngel.IO.GetChannel(1));

My questions are:

1. Will this work?
2. Should I do it, is it more efficient?
3. Realizing I use float valves differently, and alert on a "0" rather than a "1", should I change:

Code: Select all

byte iochannel0flag=0

to

Code: Select all

byte iochannel0flag=1

and finally if you want to review our discussion about the original design of this visit http://forum.reefangel.com/viewtopic.ph ... 7&start=60 but go all the way to page 7 to get to the point. Thx

Yes, you can use that.
But change it to like this if you want to check when the switch is floating.

Code: Select all

    iochannel0flag = !ReefAngel.IO.GetChannel( 0 );

The ! sign inverts the float check.

so zero and one are actually monitoring for a tank overflowing so they would need the ! because I need to know when they are floating...yes?

second, what about byte iochannel0flag=0

should it be a 1

Posted: **Sat Mar 16, 2013 7:51 pm**

The channel will be 0 when it is floating and 1 when it is not floating, assuming you mount them with the wires pointing up.
If you use the ! sign, it will change to the opposite, where 1 is floating and 0 it not floating.
Leave the variable declaration the way it is. There is no need to change that.
