IO Expansion Coding

[JoelIreland]

I there,
I can figure most things out but can't see much on the IO expansion relay.
I have one and want to do 2 things.
I want to have a button ( on press ) start feed mode or another result, and on press again it stops it.
Also i want other outputs to be status LEDs so how do i know what input / output etc it controls and what to listen for for button press?

Thanks

That's my bad...
We never had nobody doing output in the past, so we never improved the firmware on the expansion module.

So, if you want to pickup the slack and improve the firmware, we can move forward and get this wrapped up.
Want to try?

Ill see what i can do.
So as far as detecting a button press, what would be my best option?

[rimai]

You could do something like this:

Code: Select all

  if (ReefAngel.IO.GetChannel(0) && ReefAngel.DisplayedMenu==FEEDING_MODE)
    ButtonPress++;
  else
    ReefAngel.FeedingModeStart();

[JoelIreland]

So one end of button goes into channel 0 the other into one of the ground input?
Thanks.

Yeap

this is what i have ( head and loop )

<!-- LOOP -->
// First channel on left and 1st ground on left. It a push button when it on i want moon lights ( for test ) to turn on.
Moon lights are also on timer but this should over ride?
if(ReefAngel.IO.GetChannel(0)){

ReefAngel.Relay.On(MOON_LIGHTS);
}

That's fine, but this override will only work if it is after your moonlight function.
