DMX handler script
Add the following resident script with sleep interval = 0, adjust port and channel as needed
1.
if not dmxhandler then
2.
require('user.dmx')
3.
dmxhandler = DMX.init({
4.
port = '/dev/RS485',
-- RS-485 port name
5.
channels = 8,
-- number of DMX channels to use
6.
transition = 2,
-- soft transition time in seconds
7.
})
8.
end
9.
10.
dmxhandler:run()
Setter (used in other scripts)
DMX.set(channel, value)
Mark DMX objects
Create objects with DMX tag, where last part of group address is DMX address (starting from 1).
Create event script mapped to DMX tag.
1.
require('user.dmx')
2.
-- get ID as group address last part (x/y/ID)
3.
id = tonumber(event.dst:split('/')[3])
4.
-- get event value (1 byte scaling)
5.
value = event.getvalue()
6.
-- convert from [0..100] to [0..255]
7.
value = math.floor(value * 2.55)
8.
-- set channel ID value
9.
DMX.set(id, value)
Predefined scene example
The following example should be placed inside a resident script. Sleep time defines scene keep
time (at least 1 second).
1.
if not scenes then
2.
-- 3 channel scene
3.
scenes = {
4.
{ 255, 0, 0 },
5.
{ 0, 255, 0 },
6.
{ 0, 0, 255 },
7.
{ 255, 255, 0 },
8.
{ 0, 255, 255 },
9.
{ 255, 0, 255 },
10.
{ 255, 255, 255 },
