Black and white panel (vs RGB)

[strol]

Hi,
As short introduction, I can say that I have built various DMX devices, and appreciate using QLC+ for the efficiency and easy fixture design.

My projet is a large matrix of simple white LED pads (vs RGB lights).
But the famous RGB Panel fixture has not the simple "black & white" option.
Could it be designed ?
Using the RGB option takes so much DMX channels

Once upon a time I tried to make RGB matrix work with a bunch of PAR cans, so it may work.

The idea was that you either create per pixel fixture with dimmer channel or multihead fixture
with per-head dimmer channel. Then the RGB matrix would set dimmer to grayscale mapping ("value") of the RGB color.

I'm not sure if it works now nor if it worked then

There is no support for creating B/W panels though. You have to create it manually (probably by creating rows of generic dimmer channels).

This is the relevant code:

It seems that Massimo added direct support for WHITE leds in the mean time. So either you set your LED channels to WHITE or DIMMER.

Still not tested.

Thank you.
The interest was to take advantage of the RGB panel feature transfering a picture to the panel matrix.
Yes, I can anyway design a fixture matrix based on generic dimmer channels.
The harder job resulting on driving each pixel (B/W pad) as a single DMX channel th get the expected picture.
