I found an "ERROR" in your library with the software I'm using.

I found an "ERROR" in your library with the software I'm using, could I change the channels that are sent? change the start channel and end channel of the universe?

What is the error?

could I change the channels that are sent?

I don't know, I do not know your software.

change the start channel and end channel of the universe?

I don't know, I do not know your software.

My library is just a "tool" to make Art-Net projects. The examples are only to help and support you during your development. In some cases they are good enough for small and/or simple projects, but not for all.

• What is your transmitter software? QLC+? Jinx?
• What is the "error"?

• Qual é o "erro"?
  The two software that I tested and they worked, receive 0, 510 channels, but Lumikit SHOW, receives 1.512, and would have to configure to take advantage of the rest of the division of 512 / 3, the 0.666, to connect channels 511 and 512

[rstephan]

Is this the expected format for your setup?

Universe	0	0	0	0	1	1	1	1
Channel	...	510	511	512	1	2	3	...
Color	...	B	R	G	B	R	G	...

Yes, in the current examples the channels 511 and 512 are discarded.
This behavior is also described in the README.md file.
If you need a different behavior, you have to write your own onDmxFrame() function to overcome this "limitation".
