Dali Light secuence

[josep]

Hello,

We are doing a temporary project for an exhibition and I need to make a script that sends different values of regulation during a specific time to create light effects in an installation, 

(for example. initial value 20% -> (10sec) -> 60% -> (10sec) -> 75%) 

these sequences will have to be repeated without stopping when turning on the LogicMachine.
I would like to know how I can do these LM regulation ramps and how do I run it at startup?

Thank you very much.

Hi Josep,

Try this in a resident script, interval time doesn't matter.

Code:

1234567891011121314151617181920212223242526272829303132333435363738394041424344

outputaddress = '1/1/1' -- byte object -- set step values value1 = 20 value2 = 40 value3 = 60 value4 = 80 value5 = 100 -- set init value value = value1 -- set delay delaytime = 10 -- loop always while true do  -- check if value 1 needs to be written  if value == value1 then    value = value2    grp.write(outputaddress, value1)  -- check if value 2 needs to be written  elseif value == value2 then    value = value3    grp.write(outputaddress, value2)  -- check if value 3 needs to be written  elseif value == value3 then    value = value4    grp.write(outputaddress, value3)  -- check if value 4 needs to be written  elseif value == value4 then    value = value5    grp.write(outputaddress, value4)  -- check if value 5 needs to be written  elseif value == value5 then    value = value1    grp.write(outputaddress, value5)  -- fallback when value not valid  else    value = value1  end  -- delay loop  os.sleep(delaytime) end

When changing one of the declared values you need to restart the script.

If you reboot LM the sequense starts automaticly again as long as your resident script is having the active state.
