Color spectrum dimming

[Jayce]

Hello everybody!

I was wondering if it is possible to make this kind of "effect" with a simple RGB strip. When holding a simple push button set to dimming, colors of the strip would go across the spectrum of all colors (with speed / step size as I choose), when released it would stay at that color. Second button would do the same but backwards. Not sure if this would be any effective but it's the only way I thought of to make this using a physical push button. I have 3 unsigned integer group adresses (R,G,B). I tried to do it with this script I lightly modified but it doesn't work well. The script is in two event scripts, both 3 byte dimming from a pushbutton, one is set to brighter (ON) and the second one to darker (OFF).

Code:

step = 1
stepTime = 0.001
ballastAddress1 = 19 --RED
ballastAddress2 = 27 --GREEN
ballastAddress3 = 28 --BLUE
gatewayID='internal'

-----------------------------------------------------------------------------------------------------

valuein = event.getvalue()

require('user.dali')

   res, err = dalicmd(gatewayID, 'queryactual', { addrtype = 'short', address = ballastAddress1 })
   res, err = dalicmd(gatewayID, 'queryactual', { addrtype = 'short', address = ballastAddress2 })
   res, err = dalicmd(gatewayID, 'queryactual', { addrtype = 'short', address = ballastAddress3 })
 -- read ok
       if res then
     status = res:byte()
       end

while( valuein==9 ) do
 status = status + step
    if (status >254) then
             dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress1, value = 254})
             dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress2, value = 254})
             dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress3, value = 254})
         else
     dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress1, value = status})
     dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress2, value = status})
     dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress3, value = status})
    end
 valuein = grp.getvalue(event.dst)
 os.sleep(stepTime)
end
   

while( valuein==1 ) do
 status = status - step
     if (status <0) then
         dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress1, value = 0})
         dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress2, value = 0})
         dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress3, value = 0})
         else
       dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress1, value = status})
       dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress2, value = status})
       dalicmd(gatewayID, 'arc', { addrtype = 'short', address = ballastAddress3, value = status})
     end  
 valuein = grp.getvalue(event.dst)
 os.sleep(stepTime)
end

Hi
I would do it in resident script which would be enabled/disabled by your object. This script might help you https://forum.logicmachine.net/showthread.php?tid=157
