Dali interface dimming

[admin]

Right now we don't have enough resources to implement this.

Here's a function for start/stop dimming:

Code:

function bindimmer(up, down, out, event)
 local main, rev, step, val, new, delay

 step = 10 -- in %
 delay = 0.5 -- in seconds

 -- ignore "stop" command
 val = tonumber(event.datahex, 16)
 if val == 0 then
   return
 end

 -- up, normal mode
 if event.dst == up then
   main, rev = up, down
 -- down, reverse step
 elseif event.dst == down then
   main, rev = down, up
   step = -step
 -- invalid object
 else
   return
 end

 -- current output object value
 val = grp.getvalue(out) or 0

 while true do
   -- main object in "stop" state
   if not grp.getvalue(main) then
     return
   end

   -- reverse object in "start" state
   if grp.getvalue(rev) then
     return
   end

   -- get new value
   new = math.min(100, val + step)
   new = math.max(0, new)

   -- no change, stop
   if new == val then
     return
   end

   -- write new value
   val = new
   grp.write(out, new, dt.scale)

   -- wait for next run
   os.sleep(delay)
 end
end

Usage:

1. Add bindimmer function to Common functions

2. Create 3 objects:
1/1/1 - binary (dim up)
1/1/2 - binary (dim down)
1/1/3 - 1-byte scale (output)

3. Create an event script for each binary object:

Code:

bindimmer('1/1/1', '1/1/2', '1/1/3', event)

4. You can tune step and delay variables in bindimmer function to adjust dimming speed
