Link status of two different ports

[aranax]

Hey guys,
How can I check the status of a port and then change the status of another port depending on it?

Example:
Check Port 8 (to see if its ON or OFF)
if OFF turn off Port 7.

I tried something like this but it didn't compile (because im not a real coder )

if (ReefAngel.Relay.status(Port8) = Off)
{
ReefAngel.Relay.Off(Port7);
}

Thanks.

Try this:

Code: Select all

ReefAngel.Relay.Set(Port7,ReefAngel.Relay.Status(Port8));

Thanks Robert but that won't work for what I need (sorry I wasn't very clear ).

I need a failsafe to where my recirculating skimmer pump WON'T turn on (or stay on) if my Return pump is OFF. However, there are times where the Return will be ON but I want the Skimmer OFF so I can't tie the status to each other in absolute terms. Just tied together if the Return is OFF. Any ideas? Thanks.

Your original code was perfect except for two things...

status should be Status and = should be ==

Try that.

Thanks Lee. I get:

Lees_altered.cpp: In function 'void loop()':
Lees_altered:329: error: 'Off' was not declared in this scope

when I try to compile.

if (ReefAngel.Relay.Status(Port7) == Off)
{
ReefAngel.Relay.Off(Port5);
}

BTW...Happy Holidays guys. Thanks for responding given this time of year. You guys ROCK!

Try == 0 instead of == Off

Thanks Roberto. I tried that earlier and it compiled but functionality-wise it didn't work.

so weird...not ruling out user error but...

== 0 compiles but doesn't work.
!= 1 compiles and works fine.

Guess this is closed for now. Thanks guys.

If the port is in Auto mode it will be status 2...maybe?
