Visibility Timer Help

[Tankerguy72]

I am in need of a little help or clarification of what i'm doing wrong.

I have a switch that turns on my power to my tank controller. When the switch is flipped on there are a set of lights that come on for 1 second and then turn off.

I am using this code but it delays the lights shutting off not coming on. I know I am missing something simple but haven't been able to work it out yet.

                    (L:s2t_tank_power_switch, bool) 
                    if{ (E:ABSOLUTE TIME, Seconds) 1 + (>L:LED_TIMER4,Enum) }
                    (L:LED_TIMER4,Enum) (E:ABSOLUTE TIME, Seconds) >

If I understand your logic, all the time the power switch variable is true you are constantly adding 1 second to the LED_TIMER4 variable, so that variable is never less than the absolute time. You must use code that adds one second to the LED variable and then *never does it again*.

Hi Tom thank you for the reply. I am still very new in XML coding. Is there any hint you can offer to help me out on how to get started on that?

Here is some code I modified from my gauges. The first Element starts the timer by setting the LED_TIMER4_FLAG to 1. The second Element triggers the action and resets the flag to 0. Not tested.

    <Element> <!-- Set flag to start timer -->
      <Select>
        <Value> (L:s2t_tank_power_switch, bool) (L:LED_TIMER4_FLAG, enum) 0 == &amp;&amp;  if{ (E:ABSOLUTE TIME, Seconds) 1 + (>L:LED_TIMER4,enum) 1 (>L:LED_TIMER4_FLAG, enum)} </Value>
      </Select>
   </Element> 

    <Element> <!-- One second has elapsed, do the action and reset the flag -->
        <Value> (L:LED_TIMER4,Enum) (E:ABSOLUTE TIME, Seconds) > (L:LED_TIMER4_FLAG, enum) 1 == &amp;&amp;  if{ [PLACE ACTION CODE HERE] 0 (>L:LED_TIMER4_FLAG, enum)} </Value>
      </Select>
   </Element>

There are probably simpler ways to do this, but I never remember them.

Thank you for the help. I am going to go try it. Just a question if I am sticking this in a visibility for the tank power lights would the action code not be needed? just reset the flag?

 

[tgibson]

In that case you don't need the Action section, you can use the (L:LED_TIMER4_FLAG, enum) variable in the visibility section . It is TRUE (1) when needed (visible) and FALSE (0) when not (invisible).

Thanks for your help. I couldnt get it to work that way but made a work around with a visibility and an animation to make it disappear. Works perfectly now.
